It should not be overlooked that knowing how to code a website is only half of what you’ll need to know when designing a good website. The other half is a knowledge of design it’s self: as in layout, color theme, graphic manipulation, etc. There’s an entire artistic element that is often overlooked.

A website is often like a magazine advertisement or a catalog for your product. If it is not presented in a manner that is both intuitive and aesthetically pleasing you will lose business/hits. So taking a Basic level HTML course will not teach you how to make a professional website. Unless you wish to go into web entrepreneurship or something similar I suggest skipping it.
