  • Is there a unified way to know if a node is visible or not?

    - by zneak
    Hello guys, I'd like to be able to know if a node is visible and rendered on screen. As far as I know, there are at least 3 standard and easy ways of making HTML nodes not visible: Setting opacity: 0; Setting display: none; Setting visibility: hidden. I could check for just these three, but I'm afraid people can get creative when it comes to ways of hiding contents: Sending the element offscreen using negative margins; Using a width or height of 0 and hiding overflow; many more I trust people to have developed. So I was wondering if there is a standard way of determining if a node is rendered to the screen. I'm pretty sure all major browsers determine it for themselves to accelerate drawing, so maybe it's somehow exposed.

  • IE7 and IE8: Float clearing without adding empty elements

    - by tk-421
    Hello, I'm having a problem similar to the one described here (without a resolution): http://stackoverflow.com/questions/2467745/ie7-float-and-clear-on-the-same-element The following HTML renders as intended in Firefox but not in (both) IE7 and IE8: <html> <head> <style> ul { list-style-type: none; } li { clear: both; padding: 5px; } .left { clear: left; float: left; } .middle { clear: none; float: left; } .right { clear: right; float: left; } </style> </head> <body> <ul> <li>1</li> <li class="left">2</li> <li class="right">3</li> <li class="left">4</li> <li class="middle">5</li> <li class="right">6</li> <li>7</li> </ul> </body> </html> This is a form layout, and in Firefox the results appear like: 1 2 3 4 5 6 7 That's what I'm going for. In IE7 and IE8 however, the results are: 1 2 3 5 6 4 7 [Note: I don't want to float anything to the right because I want the fields on my form to left-align correctly, without a giant space in-between the floated fields to account for the parent container's width.] Apparently I need a full clear, and can probably add an empty list-item element to the list to force clearing, but that seems like a dumb solution and sort of defeats the purpose. Any ideas? I've spent a few hours reading and trying different options without success.

  • Padding/Margin/Border On Element Does Not Change DIV Height

    - by ryandlf
    Here is a very simply jsFiddle to demonstrate my problem: http://jsfiddle.net/ryandlf/mSmUv/4/ When an element has a top padding or margin and it sits on the first line within a div, the div does not respect that padding or margin and push the element down. In most cases this isn't an issue, but for example, if I have a button that has a top border and padding the top of the border will be cut off because the div is not taking into consideration the padding value. Is there a workaround for this other than just blindly setting margins or padding on every container div element and hoping I have added enough to account for any internal element that might be affected?

  • database design: table with large amount of columns (50+) or many sub tables with small amount of co

    - by Guillaume
    In our oroject we already have a lots of tables (100+). Some of them contains a lot of columns (50-100) and we are facing the need of adding more columns from time to time. What do you think is best - from maintenance and performance point of view - to split these huge tables in smaller entities or to keep the tables the way they are ? We are using an ORM tools, so we don't need to write custom request.

  • Measure text size in JavaScript

    - by kayahr
    I want to measure the size of a text in JavaScript. So far this isn't so difficult because I can simply put a temporary invisible div into the DOM tree and check the offsetWidth and offsetHeight. The problem is, I want to do this BEFORE the DOM is ready. Here is a stub: <html> <head> <script type="text/javascript"> var text = "Hello world"; var fontFamily = "Arial"; var fontSize = 12; var size = measureText(text, fontSize, fontFamily); function measureText(text, fontSize, fontFamily) { // TODO Implement me! } </script> </head> <body> </body> </html> Again: I KNOW how to do it asynchronously when DOM (or body) signals that it is ready. But I want to do it synchronously right in the header as shown in the stub above. Any ideas how I can accomplish this? My current opinion is that this is impossible but maybe someone has a crazy idea.

  • JQueryMobile 1.1.1 List items not anchoring to the left

    - by user1664935
    I'm trying to create a simple thumbnail list, the code is pretty much copied off jqm docs pages. However, when I use the code below the button element of the list isn't anchored to the left of the list item and instead appears centered...Can anyone help me? It's driving me crazy! I haven't got any styles in other than what is in the jquerymobile default page template <div id="listDiv" class="ui-content" data-role="main"> <div id="listInformation" data-role="content-primary"> <ul id="swipeMeChildrenList" data-role="listview" class="ui-listview"> <li data-corners="false" data-shadow="false" data-iconshadow="true" data-wrapperels="div" data-icon="arrow-r" data-iconpos="right" data-theme="c" class="ui-btn ui-btn-icon-right ui-li-has-arrow ui-li ui-btn-up-c"> <div class="ui-btn-inner ui-li"> <div class="ui-btn-text"> <a href="index.html" class="ui-link-inherit"> <img src="images/album-p.jpg" class="ui-li-thumb"> <p>Ha</p> </a> </div> <span class="ui-icon ui-icon-arrow-r ui-icon-shadow">&nbsp;</span> </div> </li> </ul> </div> </div>

  • jQuery show/hide for FAQ using the next() function

    - by jon_brockman
    Maybe it's because it's Friday but I'm stuck on a simple problem. I'm building a FAQ page where a user clicks on a question, revealing the answer beneath it. I'm trying to get the next() function to just grab the next instance of an "answer" div but, despite not getting any JS errors, the hidden div isn't showing. Here's the code: .answer { display:none; } $("a.question").click(function(){ $(this).next(".answer").toggle(); }); <a href="#" class="question">Queston 1</a> <div class="answer">Answer 1</div> <a href="#" class="question">Queston 2</a> <div class="answer">Answer 2</div>

  • Handling multiple media queries in Sass with Twitter Bootstrap

    - by Keith
    I have a Sass mixin for my media queries based on Twitter Bootstrap's responsive media queries: @mixin respond-to($media) { @if $media == handhelds { /* Landscape phones and down */ @media (max-width: 480px) { @content; } } @else if $media == small { /* Landscape phone to portrait tablet */ @media (max-width: 767px) {@content; } } @else if $media == medium { /* Portrait tablet to landscape and desktop */ @media (min-width: 768px) and (max-width: 979px) { @content; } } @else if $media == large { /* Large desktop */ @media (min-width: 1200px) { @content; } } @else { @media only screen and (max-width: #{$media}px) { @content; } } } And I call them throughout my SCSS file like so: .link { color:blue; @include respond-to(medium) { color: red; } } However, sometimes I want to style multiple queries with the same styles. Right now I'm doing them like this: .link { color:blue; /* this is fine for handheld and small sizes*/ /*now I want to change the styles that are cascading to medium and large*/ @include respond-to(medium) { color: red; } @include respond-to(large) { color: red; } } but I'm repeating code so I'm wondering if there is a more concise way to write it so I can target multiple queries. Something like this so I don't need to repeat my code (I know this doesn't work): @include respond-to(medium, large) { color: red; } Any suggestions on the best way to handle this?

  • jQuery .animate reveal contact form hidden in div with negative margin above header

    - by brhea
    Hi everyone, I've got my contact form hidden with a negative margin-top, so that when the visitor clicks "Contact" it reveals the div. <script type="text/javascript">$("#revealContact").click(function(){ $("#contact").animate({ marginTop: "+=620px" }, 1000); });</script> You can view it live here: http://www.brianrhea.com/index_contact.php -- click Contact link in top right My problem is that as soon as the form is submitted, it inherits the -620 margin and the success (or error) prompt is invisible. I'm running in to some other cross-compatibility issues as well with the margin spacing so I'm not even sure this is the best way to go about this. Obviously it'd be great if I could just begin with the div as display:hidden and then animate it to visible, but I haven't been able to do that. Any input is appreciated, either with advice on how to save the margin after form submission, or suggestion on better method to achieve this hide/reveal. Thanks, Brian

  • Can i make this div fill out the remaining space depending on the the sidebars widths?

    - by Marcus
    i have 4 divs inside of a div like this: <div id="Wrapper"> <div id="CoreSideBar"><!-- a sidebar to the right --> </div> <div id="SystemContent"> <div id="SystemNavigation"><!-- will be some kind of "tabnavigation" in the top of this div --> </div> <div id="PageContent"> </div> <div id="SystemSideBar"> <!-- a sidebar to the left --> </div> </div> </div> I would like the sidebars to have 200px width each and im also going to make it possible to "collapse" the sidebars so you can have more space for the PageContent div if you need it. What do i need to do to make the PageContent div fill out the remaining whitespace between the CoreSideBar and the SystemSidebar? Is this even possible in all browsers?

  • How do i create these borders in the middle?

    - by Nitesh Panchal
    Hello, I know how to generate rounded corners using images. But please have a look at the link :- http://roundedbox.andreas-kalt.de/ The rounded corners on all four corners are all images, but my question is how are those borders in the middle done? Those green color borders that surround the whole div. The tutorial is given but it is German :(. Also i don't want to use Css3 like -webkit-border-radius etc as they are not yet supported in IE Thanks in advance :)

    I'm looking for a way to implement a bracket style border around my <h2> headings; I've attached an image showing exactly what I'm trying to accomplish.

Any tips & insight are greatly appreciated.

  • HTML Line Spacing & Compact Code

    - by William Hand
    I was just wondering if there was a professional opinion on the matter of compact code. Does it really speed up page loading. Example: <body> <div id="a"></div> <div id="b"></div> </body> VS <body> <div id="a"></div> <div id="b"></div> </body> any ideas?

  • Equal height divs with footer always at bottom of tallest div

    - by nukegara
    I was wondering if this were possible, and if it is the best way to go about this: example image (since I'm not allowed to post pics yet ^^) So, not only does each column have to be of equal height, but each column also has its own individual footer. I saw this post httx://stackoverflow.com/questions/1347366/div-at-bottom-of-window-and-adaptable-height-div (I also can't post more than one link....) - how could I rework this technique to apply to the bottom of the divs and not the bottom of the window? *edit - each column will have content that will constantly change and be of variable height. I'm thinking I could just figure out the equal height columns first, then just absolute position a footer div within those columns. Does its parent div then have to be position: relative?

  • What jquery code or plugin would I use to update the position of an element created by a plugin

    - by Breadtruck
    I am using a jquery plugin from [ FilamentGroup ] called DateRangePicker. I have a simple form with two text inputs for the start and end date that I bind the DateRangePicker to using this $('input.tbDate').daterangepicker({ dateFormat: 'mm/dd/yy', earliestDate: new Date(minDate), latestDate: new Date(maxDate), datepickerOptions: { changeMonth: true, changeYear: true, minDate: new Date(minDate), maxDate: new Date(maxDate) } }); I have a collapsible table above this form that when shown, moves the form and the elements that the daterangepicker plugin is bound to, down lower on the page, but the daterangepicker appears to keep the position from when it was actually created. What code could I put in the daterangepicker's onShow Callback to update its position to be next to the element is was initially bound to? Or is there some specific jquery method or plugin that I could chain to the daterangepicker plugin so that it will update its position correctly. This would come in handy for some other plugins that I use that don't seem to keep their position relative to other elements correctly either.
