I want to take a college class that teaches xhtml, html, and css coding. Will knowledge of these functions enable me to make a complex website with databases, user accounts, etc. Or do I need to learn more website design concepts? Thanks
you need more then that but it is a start nonetheless
you need a server side language like php or asp.net, jsp , or python , ruby on rails
then a cliet side language like javascript
then database to hold everything, mysql, ms sql, oracle database
