text-indent

The text-indent CSS property sets the length of empty space (indentation) that is put before lines of text in a block.

Try it

Horizontal spacing is with respect to the left (or right, for right-to-left layout) edge of the containing block-level element's content box.

Syntax

/* <length> values */
text-indent: 3mm;
text-indent: 40px;

/* <percentage> value
   relative to the containing block width */
text-indent: 15%;

/* Keyword values */
text-indent: 5em each-line;
text-indent: 5em hanging;
text-indent: 5em hanging each-line;

/* Global values */
text-indent: inherit;
text-indent: initial;
text-indent: revert;
text-indent: revert-layer;
text-indent: unset;

Values

<length>

Indentation is specified as an absolute <length>. Negative values are allowed. See <length> values for possible units.

<percentage>

Indentation is a <percentage> of the containing block's width.

each-line

Indentation affects the first line of the block container as well as each line after a forced line break, but does not affect lines after a soft wrap break.

hanging

Inverts which lines are indented. All lines except the first line will be indented.

Formal definition

Initial value 0
Applies to block containers
Inherited yes
Percentages refer to the width of the containing block
Computed value the percentage as specified or the absolute length, plus any keywords as specified
Animation type a length, percentage or calc();

Formal syntax

text-indent = 
  [ <length-percentage> ]  &&
  hanging?                 &&
  each-line?               

<length-percentage> = 
  <length>      |
  <percentage>

Skipping indentation on the first paragraph

A common typographic practice when paragraph indentation is present is to skip the indentation for the first paragraph. As the The Chicago Manual of Style puts it, "the first line of text following a subhead may begin flush left or be indented by the usual paragraph indention."

Treating first paragraphs differently from subsequent paragraphs can be done using the adjacent sibling combinator, as in the following example:

HTML

<h2>Lorem ipsum</h2>

<p>
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse eu
  venenatis quam. Vivamus euismod eleifend metus vitae pharetra. In vel tempor
  metus. Donec dapibus feugiat euismod. Vivamus interdum tellus dolor. Vivamus
  blandit eros et imperdiet auctor. Mauris sapien nunc, condimentum a efficitur
  non, elementum ac sapien. Cras consequat turpis non augue ullamcorper, sit
  amet porttitor dui interdum.
