I first learned about HTML by studying the tags in web page source codes in college. This was not part of the curriculum: I was picking up the skill off my own bat.
Likewise for Javascript and CSS (and basic use of forms and CGI); I first learned about them by looking at inline scripts, and later learned how to invoke external script files. I was already out of uni when I began to learn about them.
