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.). <!DOCTYPE HTML> <html> <head> <title>jQu... For the above test page, when you move the mouse through both the outer and inner areas of the mouseover/mouseout rectangle, the output is...

Here's the code: <html> <body> <a href="javascript:(funct... Or, you can add this link to your bookmarks, name it "JS Executor". For a full featured JavaScript console, you may need Jash

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...

Many techniques for making rounded corners do not work well when the element being rounded is displayed on a background with a different color (or multiple colors). Example 1: Nifty Cube with JavaScript <html> <head> <base href="http://www.html.i... Example 2: modx Simple Rounded Corner Box <html> <head> <title>Round Corner</title> ... Example 3: CSS3 (does not work in IE) <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ... Example 4: This is one that actually works ! The nifty corner technique can be tweaked to be background friendly, although the JavaScript version didn't work for some reason. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ...
