Out of all the different areas of programming HTML & CSS are definitely the easiest. Languages like C# and Java can take years and years to master. Technically speaking HTML isn't really a programming language. It's a markup language like XML. But regardless it's still an essential part of web design. So for any of you web developers out there, how long did it take to get a firm grip on HTML? Enough so that you felt comfortable creating websites for clients. I think it took me around 6 months or so. The basics of CSS were easy to learn but mastering it took a while. You need a lot of experience before you start getting a good feel for CSS. HTML is more simple because you don't have different elements conflicting each other. In CSS you have to design everything so that the different styling properties work well together.
