K. Scott Allen has just published a new course: Introduction to CSS
An Introduction to CSS will give you all the knowledge you need to start working with
Cascading Style Sheets (CSS) and web design. During the course you’ll see how to achieve 2 and 3 column layouts with CSS, and learn how to work with the HTML box model and CSS cascade feature. Along the way we’ll also be styling text, changing colors, and using the flexibility and power of CSS selectors.
