CSS strikethrough different color from text?

The HTML elements del, strike, or s may all be used for a text strike-through effect. Examples:

<del>del</del>

....gives: del

<strike>strike</strike> and <s>strike</s>

....gives: strike and strike

The CSS text-decoration property with a value line-through may be used similarly. The code...

<span style='text-decoration:line-through'>
    text-decoration:line-through
</span>

...will also render to look like: text-decoration:line-through

However, the strikethrough line is typically the same color as the text.

Can CSS be used to make the line a different color?


Solution 1:

Yes, by adding an extra wrapping element. Assign the desired line-through color to an outer element, then the desired text color to the inner element. For example:

<span style='color:red;text-decoration:line-through'>
  <span style='color:black'>black with red strikethrough</span>
</span>

...or...

<strike style='color:red'>
  <span style='color:black'>black with red strikethrough<span>
</strike>

(Note, however, that <strike> is considered deprecated in HTML4 and obsolete in HTML5 (see also W3.org). The recommended approach is to use <del> if a true meaning of deletion is intended, or otherwise to use an <s> element or style with text-decoration CSS as in the first example here.)

To make the strikethrough appear for a:hover, an explicit stylesheet (declared or referenced in <HEAD>) must be used. (The :hover pseudo-class can't be applied with inline STYLE attributes.) For example:

<head>
  <style>
    a.redStrikeHover:hover {
      color:red;
      text-decoration:line-through;
    }
  </style>
</head>
<body>
  <a href='#' class='redStrikeHover'>
    <span style='color:black'>hover me</span>
  </a>
</body>
(IE7 seems to require some href be set on the <a> before :hover has an effect; FF and WebKit-based browsers do not.)

Solution 2:

As of Feb. 2016, CSS 3 has the support mentioned below. Here is a snippet from a WooCommerce's single product page with price discount

/*Price before discount on single product page*/
body.single-product .price del .amount {
color:           hsl(0, 90%, 65%);
font-size:       15px;
text-decoration: line-through;
/*noinspection CssOverwrittenProperties*/
text-decoration: white double line-through; /* Ignored in CSS1/CSS2 UAs */
}

Resulting in: Text decoration example


CSS 3 will likely have direct support using the text-decoration-color property. In particular:

The text-decoration-color CSS property sets the color used when drawing underlines, overlines, or strike-throughs specified by text-decoration-line. This is the preferred way to color these text decorations, rather than using combinations of other HTML elements.

Also see text-decoration-color in the CSS 3 draft spec.

If you want to use this method immediately, you probably have to prefix it, using -moz-text-decoration-color. (Also specify it without -moz-, for forward-compatibility.)
