Contrast Ratio Analyser
Colour Contrast The old Accessibility Evaluation and Repair Tools (AERT) suggested algorithm for determining colour contrast now directs here. The AERT algorithm was never a recommendation, and WCAG 2.0's luminosity contrast algorithm is recommended instead.

collection of 40 CSS layouts All layouts use valid markup and CSS, and have been tested successfully on Internet Explorer/win 5.0, 5.5, 6 and beta 2 preview of version 7; Opera 8.5, Firefox 1.5 and Safari 2. Each of the columns could be the longest, and for testing columns length I've used the script filler text on demand. Each layout could represent a site with five main sections: header, content, navigation, other stuff and footer. <div id="container"> <div id="header">Header</div> <div id="wrapper"> <div id="content">Content</div> </div> <div id="navigation">Navigation</div> <div id="extra">Extra stuff</div> <div id="footer">Footer</div> </div> It's almost minimal, apart from an extra wrapper around the content. Talking about CSS: each of the layouts uses float and in most of the cases negative margins. The CSS of the examples, which is embedded in both online and download versions, has been kept to the minimum in order to focus on the most important thing, as is the layout.
