HTML tells you the bare minimum of what something is; CSS describes its visual appearance. For example, HTML would say you have a div element. CSS says that div element has a 2-pixel-wide red dashed border, 5-pixel-radius rounded corners, a height of 25 pixels, and a background that changes from red to yellow as you go from left to right.
