  • External files (css, js) in embedded jetty

    - by user1938185
    With jetty, you can easily produce "html" response importing external file like : <head> <link rel="stylesheet" type="text/css" href="myStyle.css"> <script src="myScript.js"></script> <head> However, where do you put myStyle.css and myScript.js, when jetty is embedded? Especially when the jetty server is a large OpenSource project not written by you? Is there by any chance a nice out.println(???); in the servlet.doGet that would provide the answer, or something similar?

  • How to retrieve CSS style object by CSS class name?

    - by Chir
    Hi, Is it possible to get all properties of a css class associated with an element? e.g. .hightligh { font-weight: bold; border: 1px solid red; padding-top:10px; } Lets say the css class "hightlight" is assigned to div element <div class='highlight'></div> Now using JavaScript, I need to iterate through all style properties of css class "highlight" associated with the div element. Basically, I want to treat it as a JavaScript object whose properties can be accessed using iterator or for loop. Thanks in advance

  • drop down menu will not display outside containing div in IE7..

    - by playahabana
    I am tearing my hair out over this, I have a dropdown menu using CSS and jQuery (thanks to Soh Tanaka) and it works perfectly in Firefox, Safari, Google chrome and I.E. 8, but in IE 7 it will not drop down outside the 'Banner div'. It drops below the nav div however. I have moved the nav div higher in the banner the result is the same, menu drops until it reaches the border of the banner div and then vanishes.... Below is the css. This is my first website and I have some limited understanding of what I am doing. The drop down menu includes transparent png's as links (I know, I know...but it's what the Boss wants...) please could someone take a quick scan at the below CSS and let me know what is wroong? Is this some form of the IE z-index bug? i have tried all different combinations of z-index and still I can't get a different result. . The html is below as well. Thankyou in advance #banner { position: relative; width: 62.5em; height: 12em; background-color: #46280A; background-image: url('images/includes/banner2.jpg'); background-repeat: no-repeat; background-position: center; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index: 1; } /*------------------------------------SCROLLER---------------------------------------------*/ #headlines{ position: absolute; top: 1.3em; right: 2.75em; overflow: hidden; height: 2.5em; width: 24em; background-color: #000000; display: block; z-index: 3; } #news{ position: relative; height: 3.1em; line-height: 2.5em; font-size: 0.8em color: #FFFF99; white-space: nowrap; overflow: hidden; font-family: Georgia,Arial; } #scrollerglass{ position: absolute; top: 0.95em; right: 2em; height: 52px; width: 410px; border: none; padding: 0.2em 0em 0em 0em; line-height: 0.7em; text-align: center; background-image: url('images/includes/scrollerglass.png'); background-color: transparent; background-repeat: no-repeat; background-position: center; opacity: 20; z-index: 10; } #scrollerglass a i { visibility: hiddn ; } /-------------------------------------NAVIGATION-----------------------------------------/ #nav { position: absolute; top: 5.8em; left: 0.2em; font-family: trebuchet, sans-serif; font-size: 1em; line-height: 3.75em; text-align: center; color: #FFFF00; z-index: 3; } ul.navlist { list-style: none; padding: 0em; margin: 1em; float: left; width: 62.5em; background: transparent; font-size: 1em; } ul.navlist li { position: relative; /*--Declare X and Y axis base for sub navigation--*/ float: left; margin: 0em 1.4em; padding: 0em 0.7em 0em 0em; z-index: 1; } ul.navlist li a{ display: block; text-decoration: none; float: left; border: 0px solid; } ul.navlist li img{ border: 0px solid; } ul.navlist li span { trigger styles--*/ width: 1.2em; height: 5.25em; float: left; background: url(images/links/downlogo.png) no-repeat center top; } ul.navlist li span.subhover { background-position: center bottom; cursor: pointer; } ul.navlist li ul.navdrop { list-style: none; position: absolute; float: left; top: 5.3em; left: -2.4em; height: 15.0em; width: 11.25em; margin: 0; padding: 0.5em 0em 0em 0em; display: none; background-position: center; background-image: url('images/includes/slider.jpg'); background-color: transparent; background-repeat: no-repeat; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index:1; } ul.navlist li ul.navdrop li{ margin: 0em 2.3em 0em 0em; padding: 1em 0em 0em 0em; width: 8em; clear: both; } html ul.navlist li ul.navdrop li a { border: 0px solid; width: 11.25em; } html ul.navlist li ul.navdrop li a:hover { background: transparent; } <div id="banner"> <div id="headlines"> <div id="news"> Whatever we want to promote </div> </div> <div id="scrollerglass"> <a href="vintagecigars.php"> <i>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s--------<br /> <br>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s------</i></a> </div> <div id="nav"> <ul class="navmenu"> <li><a href="index.php"><img src="images/links/home.png" alt="Home" ></a></li> <li><a href="ourbar.php"><img src="images/links/ourbar.png" alt="Our Bar" ></a> <ul class="navdrop"> <li ><a href="ourcocktails.php"><img src="images/links/cockteles.png" alt="Our Cocktails" ></a></li> <li ><a href="celebrate.php"><img src="images/links/celebrate.png" alt="Celebrate in Style" ></a></li> </ul> </li> <li><a href="ourcigars.php"><img src="images/links/ourcigars.png" alt="Our Cigars" ></a> <ul class="navdrop"> <li ><a href="edicioneslimitadas.php"><img src="images/links/edicioneslimitadas.png" alt="Edition Limitadas" ></a></li> <li ><a href="cigartasting.php"><img src="images/links/cigartasting.png" alt="Cigar Tastings" ></a></li> </ul> </li> <li><a href="personalroller.php"><img src="images/links/personalcigar.png" alt="Personal Cigar Roller" ></a></li> <li><a href="galleryentrance.php"><img src="images/links/photogallery.png" alt="Photo Gallery" ></a></li> <li><a href="contactus.php"><img src="images/links/contactus.png" alt="Contact Us" ></a></li> </ul></div></div><!--end banner-->

  • CSS, HTML issue. How would I get the main body of the document to be a certain way down from the top?

    - by orano10000
    Basically I have a navbar and a title, that both have the properties, position: fixed; top: (VALUE I INSERTED); My problem is that obviously when I write the main body of the document the text is underneath the title/navbar. I need to get the text to be underneath the title and navbar, but without it having a fixed position. If any more information with code is needed, just comment saying so. Thanks in advance.

By default, 3 blocks(Content 0,Content 1,Content 2) are coming. When is clicked then (Content 1,Content 2,Content 3) will come. For this, I hide content 0 block. But layout will disturb on << click. I know this is wrong way. I should set left position instead of hiding content but it is empty I tried to set left position but no luck. Let me know How the block can be moved one by one using javascript and what is the best approach to do this?

  • jQuery: Div elements are not showing up

    I am adapting the Coverflow technique to work with a div. Following is the html: <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <style type="text/css" media="screen"> body,html { margin: 0; padding: 0; background: #000; height: 100%; color: #eee; font-family: Arial; font-size: 10px; } div.magnifyme { height: 80px; padding: 80px; position: absolute; top: 0px; left: 0px; width: 8000px; } div.wrapper { margin: 0px; height: 470px; /*border: 2px solid #999;*/ overflow: hidden; padding-left: 40px; right: 1px; width: 824px; position: relative; } div.container {position: relative; width: 854px; height: 480px; background: #000; margin: auto;} div.nav {position: absolute; top: 10px; width: 20%; height: 10%; right: 1px; } div.magnifyme div { position: absolute; width: 300px; height: 280px; float: left; margin: 5px; position: relative; border: 2px solid #999; background: #500; } </style> <script type="text/javascript" src="jquery-1.3.2.js"></script> <script type="text/javascript" src="ui.coverflow.js"></script> <script type="text/javascript"> $(function() { $("div.magnifyme").coverflow(); $("#add").click(function() { location.reload(); $(".magnifyme").append("<div id=\"div5\">hello world</div>"); $("div.magnifyme").coverflow(); }); }); </script> </head> <body> <div class="container"> <div class="wrapper"> <div class="magnifyme"> <div id="div0">This is div 0</div> <div id="div1">This is div 1</div> <div id="div2">This is div 2</div> <div id="div3">This is div 3</div> <div id="div4">This is div 4</div> </div> </div> <div class="nav"> <button type="button" id="add">Add to Deck</button> </div> </div> </body> </html> The coverflow function (included as a js file in the head section) is here. When I click the button, I was expecting it to add a DIV to the already present deck. For some reason, it doesn't show the newly added DIV.

  • background image disappears when position relative used in firefox

    - by toomanyairmiles
    So I'm trying to add a badge to the top right corner of a site I'm doing some work on. z-index works to float the object above the page content but each time i try to use position relative the background image disappears only position absolute shows the image. I don't really want to use absolute as the image needs to be positioned on the right hand side of the sites menu bar not the right hand side of the viewport. Any thoughts or advice appreciated <div class="badge-box"> <a href="http://www.google.com" class="badge">Book Now!</a> </div> <div id="header"> <a href="index.php"><img src="images/pixel.gif" width="378" height="31" alt="Welcome to Gwynfryn Farm Cottages" /></a> </div> <div id="main-menu"> <div> <a href="/">Home</a> <a href="/cottages.php">Our Cottages</a> <a href="/gwynfryn.php">Bed &amp; Breakfast</a> <a href="/rates.php">Price Guide</a> <a href="/llanbedr.php">Location &amp; Local Attractions</a> <a href="/news.php">News &amp; Special Offers</a> <a href="/contact.php">Contact Us</a> </div> </div> .badge-box { width: 1030px; margin-left: auto; margin-right: auto; border: 0px solid red; } .badge { background: url(../images/badge.png) 0px 0px no-repeat; width: 148px; height: 148px; text-indent: -10000px; position: relative; z-index: 999; } #header { width: 960px; height: 40px; margin-left:auto; margin-right:auto; margin-top:20px; padding: 20px 0px 0px 20px; background: #58564f url(../images/header-top-background.png); } #main-menu { width: 980px; margin-left: auto; margin-right: auto; height: 35px; /*background: red;*/ background: #58564f url(../images/header-bottom-background.png); font-family: Georgia, "Times New Roman", Times, serif; } #main-menu div { width: 776px; height: 35px; margin-left: auto; margin-right: auto; background: blue; } #main-menu div a { display: block; float: left; padding: 5px 10px 0px 10px; height: 30px; color: #FFFFFF; font-size: 1.2em; text-align: center; background: green; } #main-menu div a:hover { background-color: #333333; }

How do I get a 30px gap between top and box_1/2 and bottom? <html> <head> <title>Circle Motion</title> <link rel="stylesheet" type="text/css" href="styles.css" /> </head> <body> <div id="outer-wrapper"> <div id="wrapper"> <div id="top"> </div> <div id="box_1"> <img src="chrome_400x400.png" /> </div> <div id="box_2"> <img src="firefox_400x400.png" /> </div> <div id="bottom"> <p>All Rights Reserved - CSS_maniac 2012 ©</p> </div> </div> </div> </body> </html> CSS /* My CSS */ html { height: 100% } body { background-color: grey; } #outer-wrapper { height: 100%; width: 1000px; margin: 0px auto; background-color: #EAFFDB; -moz-border-radius: 15px; border-radius: 15px; } #wrapper { height: 100%; width: 960px; margin: 0px auto; background-color: #EAFFDB; overflow: hidden; } #top { width: 900px; height: 110px; margin-top: 35px; margin-left: 30px; margin-right: 30px; background-color: white; -moz-border-radius: 15px; border-radius: 15px; } #box_1 { width: 430px; height: 430px; background-color: white; -moz-border-radius: 15px; border-radius: 15px; float:left; margin-left: 30px; text-align: center; } #box_2 { width: 430px; height: 430px; background-color: white; -moz-border-radius: 15px; border-radius: 15px; float:right; margin-right: 30px; text-align: center; } #box_1 img { margin: 15px 0px; } #box_2 img { margin: 15px 0px; } #bottom { width: 900px; margin: 0px auto 0px auto; text-align: center; background-color: white; -moz-border-radius: 15px; border-radius: 15px; clear:both; } /* Classes */ .clear { clear: both; }

  • Position:absolute

    - by Andrew
    I have I have a div called logo. I want the logo to be on top of other areas and to overlap into the the preface top of a drupal site, the logo currently sits in the header area. I looked up position absolute and I think that what I need to use but when I use position absolute the logo disappears, I can see it if I use position fixed, relative etc. I thought the logo was being hidden because I was not using a z-index but even with that I cant see the logo. What am I doing wrong? #logo { position: absolute; top: 30px; /* 30 pixels from the top of the page */ left: 80px; /* 80 pixels from the left hand side */ z-index:1099; border: 1px solid red; /* So we can see what is happening */ } Also does anyone know of a really good free online css course? Here is some additional information, namely the CSS and the page.tpl.php: <?php // $Id: page.tpl.php,v 1.1.2.5 2010/04/08 07:02:59 sociotech Exp $ ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="<?php print $language->language;

  • Appcelerator Titanium - auto height table views break with shortish text

    - by ceejayoz
    I posted this on the Appcelerator Titanium dev Q&A site, but maybe someone here has had this issue... KitchenSink 1.1 illustrates this issue. In table_view_api_auto_height.js, changing row: addRow(0,'This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text.'); to something like: addRow(0,'This is some long text. This is some long text.'); results in incorrect left padding on the row. See screenshot:

  • Swap CSS class on the basis of Scroll Position with Javascript

    - by Brian
    I'm looking to re-create the Apple Store shopping cart sidebar. http://store.apple.com/us/configure/MB535LL/A?mco=MTA4MTg3NTQ It is similar to "position: fixed" except that it starts out as "position: absolute" with the CSS class "pinned_top" and then switches to CSS class "floating" when a certain scroll-y position is reached. I've looked EVERYWHERE for this, it seems a tutorial should be obvious but I'm yet to find anything. Any help?

  • How do I use the subversion revision of a css file to prevent browser cache

    - by Clayton
    StackOverflow implements it like this: <link rel="stylesheet" href="http://sstatic.net/so/all.css?v=4542"> Every time the referenced files change, the href attribute of the link tag is updated in the HTML code, thus supporting caching and updated referenced files. My question - how do you retrieve the subversion version of that css file to include in the link? Subversion keywords only tell you the revision of the file you are currently in. I'm working with PHP/CodeIgniter + jQuery.

  • Ball bouncing at a certain angle and efficiency computations

    - by X Y
    I would like to make a pong game with a small twist (for now). Every time the ball bounces off one of the paddles i want it to be under a certain angle (between a min and a max). I simply can't wrap my head around how to actually do it (i have some thoughts and such but i simply cannot implement them properly - i feel i'm overcomplicating things). Here's an image with a small explanation . One other problem would be that the conditions for bouncing have to be different for every edge. For example, in the picture, on the two small horizontal edges i do not want a perfectly vertical bounce when in the middle of the edge but rather a constant angle (pi/4 maybe) in either direction depending on the collision point (before the middle of the edge, or after). All of my collisions are done with the Separating Axes Theorem (and seem to work fine). I'm looking for something efficient because i want to add a lot of things later on (maybe polygons with many edges and such). So i need to keep to a minimum the amount of checking done every frame. The collision algorithm begins testing whenever the bounding boxes of the paddle and the ball intersect. Is there something better to test for possible collisions every frame? (more efficient in the long run,with many more objects etc, not necessarily easy to code). I'm going to post the code for my game: Paddle Class public class Paddle : Microsoft.Xna.Framework.DrawableGameComponent { #region Private Members private SpriteBatch spriteBatch; private ContentManager contentManager; private bool keybEnabled; private bool isLeftPaddle; private Texture2D paddleSprite; private Vector2 paddlePosition; private float paddleSpeedY; private Vector2 paddleScale = new Vector2(1f, 1f); private const float DEFAULT_Y_SPEED = 150; private Vector2[] Normals2Edges; private Vector2[] Vertices = new Vector2[4]; private List<Vector2> lst = new List<Vector2>(); private Vector2 Edge; #endregion #region Properties public float Speed { get {return paddleSpeedY; } set { paddleSpeedY = value; } } public Vector2[] Normal2EdgesVector { get { NormalsToEdges(this.isLeftPaddle); return Normals2Edges; } } public Vector2[] VertexVector { get { return Vertices; } } public Vector2 Scale { get { return paddleScale; } set { paddleScale = value; NormalsToEdges(this.isLeftPaddle); } } public float X { get { return paddlePosition.X; } set { paddlePosition.X = value; } } public float Y { get { return paddlePosition.Y; } set { paddlePosition.Y = value; } } public float Width { get { return (Scale.X == 1f ?

} Thanks in advance for any tips on the 4 issues. EDIT1: Something isn't working properly. The collision axis doesn't come out right and the interpolation also seems to have no effect. I've changed the code a bit: private bool ShapesIntersect(Paddle paddle, Ball ball) { overlap = 1000000f; //large value overlapAxis = Vector2.Zero; MTV = Vector2.Zero; foreach (Vector2 ax in Axes) { float[] pad = paddle.ProjectPaddle(ax); //pad0 = min, pad1 = max float[] circle = ball.ProjectBall(ax); //circle0 = min, circle1 = max if (pad[1] < circle[0] || circle[1] < pad[0]) { return false; } if (Math.Abs(pad[1] - circle[0]) < Math.Abs(circle[1] - pad[0])) { if (Math.Abs(overlap) > Math.Abs(-pad[1] + circle[0])) { overlap = -pad[1] + circle[0]; overlapAxis = ax * (-1); } //to get the proper axis } else { if (Math.Abs(overlap) > Math.Abs(circle[1] - pad[0])) { overlap = circle[1] - pad[0]; overlapAxis = ax; } } } if (overlapAxis != Vector2.Zero) { MTV = overlapAxis * Math.Abs(overlap); } return true; } And part of the Update method: if (ShapesIntersect(paddleRight, ball)) { isColliding = true; if (MTV != Vector2.Zero) { ball.X += MTV.X; ball.Y += MTV.Y; } //test if (overlapAxis.X == 0) //collision with horizontal edge { } else if (overlapAxis.Y == 0) //collision with vertical edge { float factor = Math.Abs(ball.ballCenter.Y - paddleRight.Y) / paddleRight.Height; if (factor > 1) factor = 1f; if (overlapAxis.X < 0) //left edge? ball.Speed = ball.DEFAULTSPEED * Vector2.Normalize(Vector2.Reflect(ball.Speed, (Vector2.Lerp(new Vector2(-1, -3), new Vector2(-1, 3), factor)))); else //right edge? ball.Speed = ball.DEFAULTSPEED * Vector2.Normalize(Vector2.Reflect(ball.Speed, (Vector2.Lerp(new Vector2(1, -3), new Vector2(1, 3), factor)))); } else //vertex collision??? { ball.Speed = -ball.Speed; } } What seems to happen is that "overlapAxis" doesn't always return the right one. So instead of (-1,0) i get the (1,0) (this happened even before i multiplied with -1 there). Sometimes there isn't even a collision registered even though the ball passes through the paddle... The interpolation also seems to have no effect as the angles barely change (or the overlapAxis is almost never (-1,0) or (1,0) but something like (0.9783473, 0.02743843)... ). What am i missing here? :(

  • Performance of tokenizing CSS in PHP

    - by Boldewyn
    This is a noob question from someone who hasn't written a parser/lexer ever before. I'm writing a tokenizer/parser for CSS in PHP (please don't repeat with 'OMG, why in PHP?'). The syntax is written down by the W3C neatly here (CSS2.1) and here (CSS3, draft). It's a list of 21 possible tokens, that all (but two) cannot be represented as static strings. My current approach is to loop through an array containing the 21 patterns over and over again, do an if (preg_match()) and reduce the source string match by match. In principle this works really good. However, for a 1000 lines CSS string this takes something between 2 and 8 seconds, which is too much for my project. Now I'm banging my head how other parsers tokenize and parse CSS in fractions of seconds. OK, C is always faster than PHP, but nonetheless, are there any obvious D'Oh! s that I fell into? I made some optimizations, like checking for '@', '#' or '"' as the first char of the remaining string and applying only the relevant regexp then, but this hadn't brought any great performance boosts. My code (snippet) so far: $TOKENS = array( 'IDENT' => '...regexp...', 'ATKEYWORD' => '@...regexp...', 'String' => '"...regexp..."|\'...regexp...\'', //... ); $string = '...CSS source string...'; $stream = array(); // we reduce $string token by token while ($string != '') { $string = ltrim($string, " \t\r\n\f"); // unconsumed whitespace at the // start is insignificant but doing a trim reduces exec time by 25% $matches = array(); // loop through all possible tokens foreach ($TOKENS as $t => $p) { // The '&' is used as delimiter, because it isn't used anywhere in // the token regexps if (preg_match('&^'.$p.'&Su', $string, $matches)) { $stream[] = array($t, $matches[0]); $string = substr($string, strlen($matches[0])); // Yay! We found one that matches! continue 2; } } // if we come here, we have a syntax error and handle it somehow } // result: an array $stream consisting of arrays with // 0 => type of token // 1 => token content
