Question on front-end developing

Definitely not enough to only know CSS/HTML/Js. The most painful part of being a front-end developer is about how much you actually have to learn, as soon as you learn one framework, the next one becomes the new good thing. Companies usually list what skills they exactly want you to have so I'd search for jobs first, and then adapt my learning schedule to it. I don't wish to discourage you from what you want to do but the remote market is really hard to get into, especially with the amount of Indians willing to work for insanely low salaries.
