How to load WP UI script in the footer and disable default CSS

You can override the default css easily by putting it in a div on the page/post like so:

<div id="specialtabs">
[wptabs mode="horizontal"]

[wptabtitle]Your title[/wptabtitle]
[wptabcontent]
Your content
[/wptabcontent]

[/wptabs]
</div>

Then add css to your theme to position it into the footers area(note below is just an example. must come up with own numbers):

#specialtabs {
	position:absolute;
	width:200px;
	height: auto;
	padding:8px 10px 20px 10px;
	border:1px solid #000;
	border-top:2px solid #000;
	border-left:1px solid #000;
	background-color:#fff;
	z-index: 0;

	left: 50%;
	margin-left: 255px;
	margin-top: 150px;
	top: -150px;
        background-image:url(www.urlhere.com/image.jpg);
        background-postition: top;
        background-repeat: repeat-x;
	}

And thats how you do that.

Thanks akridgeblue, but I want to do these things for site performance reasons, not simply to override CSS.

Ah I see. Yeah thats just a quick and dirty fix. Hmm well. I guess it all depends on your footer and theme.

You can use a plugin to add widgets to the footer(forgot the name) and then use the ‘Enhanced text’ plugin widget that allows all-sorts of code, css and what not.
