The Transition to CSS
This is an older article written at the time when many web designers were still using HTML to format and layout their web pages. Some web designers were reluctant to use CSS because of browser support and compatibility.
I republished this article because it has some good information about how different technologies have to be compatible. Especially for beginning web designers who might not understand why we are not yet using HTML 5, the latest version of HTML, this article gives a little history of how different technologies have to catch up with each other.
