Some folks concentrate on print work. Others focus on Web work. Some do both. If you're a print designer and you want to expand into Web design, there are some things you need to know before making the transition. Some of your skills will transfer over quite nicely. But there are additional skills you'll need to acquire beyond knowing what colors look good together and which end of the font is up. You could (and probably should) start by creating your own Web site. That's a good learning ground as well as being the first piece in your Web design portfolio.
