Cross-Browser Compatibility
The head-ache of all website designers.
One of the toughest things to do in website design is to make sure a website looks the same across multiple browsers. It doesn't sound like much, but take a look below at the 2009 market share breakdown of web browsers. Internet Explorer alone can vary in the way it displays and performs from version to version, making it absolutely necessary to make every effort to create a compliant, friendly HTML document for your viewers.
Website browsers interpret HTML code and render a web page based on the information they have programmed with. To ensure your website looks uniform through as many different browsers as possible, a web designer needs to follow strict standards as outlined by the W3C (World Wide Web Consortium ).
