Browsers

The top browswers include Internet Explorer, Firefox, Opera, and Chrome.There is conflicting data about which browser is most widely used. Explorer has always been number one but Firefox use has graduated to a near tie in popularity. The changing useage makes it important that proper testing is done before a site is launched. Internet Explorer renders certain CSS and HTML differently than Firefox. If you test your pages in Chrome and Firefox, then it should be ok with Opera,without many differences, but certain versions of Explorer may be different. One way to work with the differnt style rendering is to publish different CSS files for each browser. Specify in the head tag which CSS to load in relation to the broweser accessing the page. The code that tells the page to load a specific CSS is a conditional comment.
