Before the Web 2.0 revolution, websites were built with content in a series of tables that were constructed offline and then uploaded onto the web. This technique was extremely heavy on servers and the websites would show up differently on different browsers. Once CSS made its way onto the web-scene, however, tables were almost completely scrapped. Under CSS, content is placed “freely” on a web page, which means that there are no heavy tables to upload or view. This makes the web page show up the same way on all browsers, as well as making the web page more easily accessible.
