  • Html newbie! background-image question

    - by Kevin Li
    Hi! I'm learning HTML and I wanted to practice by recreating a invoice sent to me by Electronics Expo. However, I used the background-image property and repeated it by repeat-x and now, the background stretches across the page so much that it has a horizontal bar to drag. http://htmlpocketreference.110mb.com/index.html You can see what I did in my link above. Also, I would really appreciate some advice on simplifying my CSS coding. It seems really messy and I have to move every element once something changes. -.- Thanks!

  • Why won't my images align properly?

    I'm trying to make a dynamically sizable title banner, using fairly simple image tricks. I place the banner image in a table cell, and set the background-image of the table row to a one-pixel-wide repeat of the banner's right-most pixel column. Thus, the banner image appears to stretch to fit the screen width without stretching the logo. The code below is my entire page so far, and the problem is shown in a red circle in the screenshot. This is the transition where the main image ends and the one-pixel-wide background image begins. It appears that the one-pixel-wide bar at the end is compressed by one pixel - making the tops align properly, while the bottoms are one pixel off. I should add that I have checked the images more than once to make cure they the image data is correct. They are %100 accurate as far as MSPaint is concerned. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body bgcolor="#000000"> <form id="form1" runat="server"> <div> <table style="width:100%; "> <tr style="background-image: url('Images/Banners/WebBannerWideBar.png')"> <!--WebBannerWideBar is 1x100 px--> <td> <img alt="Angry Octopus" src="Images/Banners/WebBannerWide.png" /> <!--WebBannerWide is 760x100 px--> </td> </tr> </table> </div> </form> </body> </html>

  • best method for background uploader in Android

    - by Dr.Dredel
    Problem: I want to write a process that will allow a user to take photos with the device and for those photos to then be uploaded to some listener in the cloud. The user should not have to do anything to initiate the upload, a background listener would just watch the folder and as long as it finds files in it it would upload them and delete them. Two problems: 1) how to keep the program running in the background even after the user is no longer taking pictures (and if they reboot the device for it to wake up and finish the uploads, if any remain) 2) assuming the connection is spotty (as it always is) how to verify that a given image has completed its upload, and if not, to resubmit it. I don't need any code examples, I just would like opinions on the best strategy to get this implemented. I was going to use Apache commons and just do an upload to a PHP, but am not sure what sort of error checking exists to take into account a connection drop mid file. TIA.

  • Image as a background of a form in Delphi

    - by Averroes
    I'm using Delphi 2006. I have a few PNG images with transparencies and I have to create a GUI using them (top bar, left panel...). The images have different aligns properties. One of the images is the background of the form. The problem here is that I can't align it as alClient because it only occupies the rectangular zone that the other images have left, showing the naked canvas in their transparent zones. What I need is that the background image is put behind all the other images and taking all the canvas size. Is there anyway to do this? I know I can do this writting some logic in the OnResize event of the form but I was just curious if I was missing something. Thanks.

  • background semitransparent div

    - by plasticrabbit
    I want to show some dialog (absolute positioned div), and I want to show it above semitransparent 100% div, so everything on background will be dimmed. I have managed it by <div class='transpBox'></div> .transparentBox { position: absolute; top: 0px; left: 0px; width: 100%; height: 100%; background-color: #white; opacity: 0.9; z-index: 499; } This is all right, but when dialog height is more than browser height and you scroll down, you see that transparent div is not in full screen. What is proper way to make such thing?

    - by pheromix
    There are images displayed inside a HTML table in a PHP code : The code of this table is : for ($i = 0; $i < $data['list']['cnt']; $i++) { $tabRows[$i][1]['width'] = "45%"; $tabRows[$i][1]['align'] = "center"; $tabRows[$i][1]['value'] = '<img src="'.HTTP_FIGURES.$data['list'][$i]['fig_image'].'" />'; } As you can see the background of the images are seen and they make the page dirty.
