Check out meteorjs. Javascript has a huge amount of buzz and usage these days, and meteorjs is a fairly simple fully integrated environment that allows you to do just about anything. I don't use it - I have been developing software since the early 90s and I am currently working in RoR. But when I want to play around, it's in meteorjs. In my opinion, too many teams are using an environment that is too complex, ensuring that nothing is predictable.

Although I do like Meteor, I don't think it's the right choice for the OP. Surely Meteor is easy to grasp, but its fundamentals rely on many technologies (React/Blaze, MongoDB, NodeJS) that a out-of-practice developer may struggle a little.

That being said, I'd recommend the OP to dive into modern CSS frameworks (Bootstrap, Semantic UI, Materialize, to name a few) and learn more JavaScript. After that he will probably feel what he likes/dislikes more and find the most suitable framework for his needs.
