I’ve always built every site in HTML, CSS, and PHP. For me, that’s usually plenty. I don’t incorporate any web apps or anything like that. I generally just need to manage content and have an email form. For any stylistic pop, I generally find that CSS3 does the trick with whatever transitions or animations I might want, etc. And I use PHP to validate forms client side.
But a lot of times I’ll be trying to figure out how to do something and someone will suggest some jQuery plugin that already does it. It’s REAAAALLY tempting to take advantage of all these but is it always the right solution?
Thoughts? Should I fully learn it and when should I use it?
