CSS Text

CSS has a lot of properties for formatting text.

Text Color

The color property is used to set the color of the text. The color is specified by:

  • a color name – like “red”
  • a HEX value – like “#ff0000”
  • an RGB value – like “rgb(255,0,0)”

The default text color for a page is defined in the body selector.

Example

body {
  color: blue;
}

h1 {
  color: green;
}

Text Color and Background Color

}

h1 {

  color: white;
}

div {
  background-color: blue;
  color: white;
