I have a gripe with all these online courses. They only target beginners or they target advanced users. I have done hours of googling to find a stuctured course which teaches "intermediate" CSS...I am not a CSS newbie but I am also not an expert who is interested in animations, etc<p>I can may be use bootstrap and make grid based layouts that are non responsive. I am yet to find a course which will help me make, lets say, a hacker news UI or reddit UI. I can guarantee you that all these courses fall short of that.
