The ones created by the World Wide Web Consortium — the people who invented the Web itself. The W3C created these standards so the Web would work better for everyone. For the most part, modern browsers released since the end of 2002 support these standards reasonably well; older browsers, in particular version 4 series and before, do not.
You might consider upgrading your browser. Doing so will improve your Web experience in general, enabling you to view and use more sites as their creators intended.
The following browsers support numerous Web standards including CSS, (X)HTML, and the DOM (a universal means of controlling the behavior of Web pages), and are recommended for optimal viewing of the site:
Mozilla Firefox for all platforms
Internet Explorer 6 or higher for Windows
Safari for Macintosh
Opera 8 or higher for all platforms
Please note that this page does not pretend to be an exhaustive list of browsers that support Web standards, nor a test of browser compliance, nor a side-by-side comparison of various manufacturers’ browsers.
