One way to vertically center a line of text in a container div is to set line-height to be the same as the height of the container. But that requires specifying line-height in pixels. This technique avoids that.

The events mouseover and mouseout are fired when the mouse enters/leaves the element where the event handlers are registered, and any nested elements which do not handle these events (because of event bubbling ). The events mouseenter and mouseleave are fired only when the mouse enters/leaves the specified element. Nested elements do not come into play. This following is a test page. You need Firebug to view the console output. Or use the JavaScript Executor bookmarklet. If none of these are available, an alert will popup (but you won't be able to fully test with alert.).

jQuery event delegation allows you to bind event handlers to elements not yet created, under these conditions:
The DOM element must nest inside the element to which the event is delegated to
The inner element must not stop event bubbling
The opposite of delegate is undelegate .

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

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).
