However, how about a freelance web designer/developer. If you are making a simple website for a someone, how many languages do you use? Has CSS3 with all the animations, transitions, and transformations changed the amount of other languages needed? Do freelancers make websites with HTML and CSS exclusively?
Having built my own website and now learned how many things can be done is CSS3, I am curious about the purpose of using other languages in a website. Obviously, if you are needing to access a database to retrieve stored information that is one thing, but what about a simple website for someone or a client?
Let me know in the comments what you use or know of others using. I think this could be a neat topic to discuss.
