::first-line

The ::first-line CSS pseudo-element applies styles to the first line of a block-level element. Note that the length of the first line depends on many factors, including the width of the element, the width of the document, and the font size of the text.

/* Selects the first line of a <p> */
p::first-line {
  color: red;
}

Example

HTML

<p>Styles will only be applied to the first line of this paragraph.
After that, all text will be styled like normal. See what I mean?</p>

<span>The first line of this text will not receive special styling
because it is not a block-level element.</span>

CSS

::first-line {
  color: blue;
  text-transform: uppercase;
