text-indent

The text-indent leaves empty space on the first line in a text-block.

text-indent: <value>;

The amount of indentation can be specified by using percentages or length values (px, em, etc.).

Specifying indentation length with percentages:

p {
  text-indent: 20%;
}

Specifying indentation length with px and em values:

.div1 p {
  text-indent: 50px;
}

.div2 p {
  text-indent: 2em;
}
