Getting Fancy With Text Decoration in CSS

They say good things come to those who wait, and this turns out to be very true when it comes to text decoration on the web. The CSS Text Decoration Module Level 3 defines a few great new ways to decorate text on the web, and browsers are finally starting to have good support for them. The times of using border-bottom instead of a proper text underline in order to get a different underline color may finally come to pass.

Results may vary: support is still limited, so the examples in this post may not display correctly depending on the browser you're using.

text-decoration

The text-decoration property used to be only about a choice between values of none, underline, overline and line-through, but with the new recommendation is becomes a shorthand for the new text-decoration-color, text-decoration-style and text-decoration-line properties. For example, here’s a colored double underline:

.fancy {
  -webkit-text-decoration: hotpink double underline;
  text-decoration: hotpink double underline;
}

Fancy Underline

text-decoration-color

Works just as you would imagine. Finally a way to change the text decoration color!

text-decoration-style

text-decoration-style is used to define the type of text decoration, and the new recommendation brings two new values: double and wavy:

.wavy {
  text-decoration: underline;
  -webkit-text-decoration-color: salmon;
  text-decoration-color: salmon;
  -webkit-text-decoration-style: wavy;
  text-decoration-style: wavy;  
}

Wavy Decoration

text-decoration-line

text-decoration-line accepts values of underline, overline, line-through and blink (blink is deprecated however):

.strike {
  -webkit-text-decoration-color: red;
  text-decoration-color: red;
  -webkit-text-decoration-line: line-through;
  text-decoration-line: line-through;
}

Strike This

text-decoration-skip

With text-decoration-skip we can avoid having the decoration step over parts of the element its applied to. The possible values are objects, spaces, ink, edges and box-decoration.

  • ink: Finally, a way to prevent text decoration from overlapping glyph descenders:
.ink {
  -webkit-text-decoration: darkturquoise solid underline;
  text-decoration: darkturquoise solid underline;
  -webkit-text-decoration-skip: ink;
  text-decoration-skip: ink;
}

  • objects: The text decoration skips elements that have a display of inline-block. It’s also the initial value:
<p class="super">
  Getting <span style="display: inline-block;">Very</span> Fancy
</p>
.super {
  -webkit-text-decoration: peru solid overline;
  text-decoration: peru solid overline;
  -webkit-text-decoration-skip: objects;
  text-decoration-skip: objects;
}

Getting Very Fancy


The remaining values are not yet well supported by browsers:

  • spaces: The decoration skips spaces and punctuation.
  • edges: Creates a gap when two elements with text decoration are next to each other.
  • box-decoration: The decoration skips any inherited margin, padding or border.

text-underline-position

With text-underline-position we have yet another way to control the positioning of text decoration in relation to the glyphs. The possible values are auto, under, left and right.

With auto, the initial value, browsers will usually place the decoration close to the text baseline:

.auto {
  -webkit-text-decoration: slateblue solid underline;
  text-decoration: slateblue solid underline;
  -webkit-text-underline-position: auto;
  text-underline-position: auto;
}

…and notice now how, with under, the decoration is placed after the text descenders:

.under {
  -webkit-text-decoration: slateblue solid underline;
  text-decoration: slateblue solid underline;
  -webkit-text-underline-position: under;
  text-underline-position: under;
}

The left and right values for text-underline-position are used to control text decoration in vertical writing modes.

🌈 Now go on and impress us with some fancy text decoration!
