Cross browser compatibility

Steps to make a web-page cross browser compatible:

• Set Doctype to XHTML.
• Remove browser default built-in styles. Use any of the CSS-resets available, for example Eric Meyers.
• Use the W3C Markup Validation Service and the W3C CSS Validation Service to verify HTML/CSS.
• Set the default W3C style sheet, or use a CSS framework like Twitter Bootstrap.
• Use a Javascript framework, for example jQuery.
