Hex or Decimal? Until recently, it was assumed that colors should always be declared in RGB hexadecimal notation. In fact, I still meet designers and developers who are completely unaware that they have alternatives. RGB decimal has been around for quite awhile and will work in any browser you want to throw it at. But which is “better”? I personally find that it’s much easier to envision a color in decimal numbers (which I’ve used all my life) than in hex values. I can look at the value 135, 127, 107 and know it’s a reddish beige much faster than if I see 877f6b.

The text portion of an HTML tag is called the selector. For example, h1 is the selector for the tag. The HTML selector is used in a CSS rule to redefine how the tag displays. -Class.
