color

Color not only brings your site to life, but also helps convey the mood and evokes reactions.

There are three ways to specify colors in CSS:

RGB values
hex codes
color names

Color pickers can help you find the color you want.

It is important to ensure that there is enough contrast between any text and the background color (otherwise people will not be able to read your content).

CSS3 has introduced an extra value for RGB colors toindicate opacity. It is known as RGBA.

CSS3 also allows you to specify colors as HSL values,with an optional opacity value. It is known as HSLA.
