Dreamweaver helps you with your html, but when it comes to Css, you’re on your own. You need to know how to understand the code, what the code is for, and as many of the rules as you can.
I’ve been doing web development for more than 13 years, and when I started using Css it was strange.
Then, for those of you moving from print to web, Css is a real monster. 50 percent of my clients have been doing print layout for decades and Css scares them to death.
Css is the buzz in web development NOW. If you don’t know Css, give up getting a web job.
I can make it easy for you to understand it and use it.
