If you are looking for a solution for a progress bar, I direct you to the following resources: Bare Naked App provides a simple and elegant solution based on pure CSS with two images. You control the percentage of completion through the background-position attribute of the CSS. HTML:
<img src="/images/percentImage.png" alt="... CSS: img.percentImage { background: white url(/imag... Images: (percentImage.png) (percentImage_back.png) WebAppers extended the above solution with JavaScript. They also added several colored images: JQuery UI has a built-in progress bar widget. However, if you want to get to understand some of the foobar needed to get CSS to work (in general) through this example, stay with me for the rest of this note. Initially I was thinking, a progress bar should be easy: just make...

I didn't know how hard it was to vertically align something to the middle until I had to do it. An excellent writeup about the various techniques (or should I say hacks?) to achieve this is here: http://blog.themeforest.net/tutorials/vertical-centering-with-css/ Here I present a technique with the help of jQuery. To make it simple, what I'm doing is to display a single line of text in the middle of the page instead of at the top. The markup is made simple because the logic is moved to JavaScript. There are two requirements to make this work: The parent container uses relative positioning jQuery code added to re-position the content with absolute positioning
<!doctype html> <html> <head> <title>Vert... For some reason, the following code did not work although...

It renders like this in IE 7:
However, when you try to scroll to the bottom of the dialog, IE takes long time to respond, the it messes up the title bar:
Everything works fine if you take away the relative position in CSS:
<style type="text/css">
#dialog .input {

Use the siblings function to find all siblings of the current jQuery object:
$(this).siblings()
which is equivalent to:
$(this).parent().children().not(this)
Or, use an optional selector to further limit the selection of siblings:
$(this).siblings('li .hilighted')

If CSS3 border-image is properly supported, making a rounded corner box is very easy. You just need a round corner image like this: The following markup:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ... would render like this (try it in Firefox 3.5 and Google Chrome): However, IE as of version 8.0 does not support border-image . So until border-image is reliably supported in all major browsers, we still have to rely on tried and true tricks to make it work. In general, I found three general categories of tricks to make rounded corners: Good old tables. This trick creates a table of 9 cells and uses the 8 cells on the perimeter to render the borders and rounded corners. The central cell is used for...

The code presented here is a simple implementation of a tab set. It is used to demo how a tab set could be implemented. The code is stand alone and does not depend on any JavaScript libraries. Multiple tab sets within the same page is supported.
The HTML markup is fairly simple:
Tabs sets are contained within a DIV element with class name "tabsContainer".
Define a UL list for the tabs.
Follow the UL list with equal number of DIVs for the tab contents.
The Nifty Corners Cube technique is used to draw the rounded corners (original form, not the enhanced JavaScript form).
