I'm looking for an online or Seattle-based class where I can learn Javascript, CSS, and HTML5. I know the basics, so I guess I'm looking for an intermediate to advanced class where I mainly get to practice and perfect the concepts. I could certainly just find great websites and walk through tutorials on my own time, but I need the external motivation and structure of a class. I'm expecting to pay for this training. I'm asking on SLL and GSLUG because I need something FLOSS-friendly. I should be able to do all the assignments on a GNU/Linux desktop without issue.
I have lots of experience with devops and backend software. I'm fairly solid on programming fundamentals. I'm okay with math and computer science. I'm great with Bash, Python, Java, PHP, and C/C++. I've used GNU/Linux almost exclusively for the last decade. Anyone got a recommendation?
