Where to start with web development?

Hello guys...

I am simply a programmer, who has some knowledge with programming in c++/c and python, and would like to delve into web development, but are bit unsure on where I should start and how.

It seem to me web development isn't just development as programmer, with all the different types of languages for different parts of the web development process... (html, css, django, javascript, PHP and so on..)... I mean god damn why is it so complicated.

I thought learning programming in c/c++ had a steep learning curve, but this is just a mess..

If you guys had to recommend a guy like me, into web developement, where should I then start.. What should I learn first and how should I build upon that?.. It seems like html/css is frontend stuff and django/php is more backend stuff if I am wrong?
