Intended-vertical-left align tabs

By using the OuterCssClass="" and CssClass proprties of the RadTabstrip control along with the right CSS class selectors you can achieve intended-vertical-left align tabs. Example:

CSS

<style type="text/css">
	.border {
		border-bottom: 1px solid grey; 
	}
	 .RadTabStripVertical li.rtsLI .new, .new {
		padding-left: 10px !important;
	}
	.RadTabStripVertical li.rtsLI .new1, .new1 {
		padding-left: 20px !important;	
	}
	.RadTabStripVertical li.rtsLI .new2, .new2 {
		padding-left: 30px !important;
	}
</style>
