CSS - text-decoration

Example

h1.under {
    text-decoration: underline;
}
h1.over {
    text-decoration: overline;
}
p.line {
    text-decoration: line-through;
}
p.blink {
    text-decoration: blink;
}
a.none {
    text-decoration: none;
}
p.underover {
    text-decoration: underline overline;
}

<h1 class="under">Underlined Header</h1>
<p class="line">If you want to strike out text, use line-through.</p>
<p class="blink">This text might blink for you - if you use Explorer, it will not.</p>
<h1 class="over">and now an overlined header.</h1>
<p>This <a class="none" href="textdecoration.html">link will not be underlined</a>, as most links are by default. Be careful with removing the text decoration on links since most users depend on the underline to signify a hyperlink.</p>
<p class="underover">This text has both underline and overline.</p>

Values

The text-decoration property is a shorthand and can use the values of each of the three longhand properties: text-decoration-line, text-decoration-color, and text-decoration-style

Formal syntax

<a href="css/text-decoration-line" title="none | [ underline || overline || line-through || blink ]"><'text-decoration-line'></a> <a href="css/value_definition_syntax#double_bar" title="Double bar">||</a> <a href="css/text-decoration-style" title="solid | double | dotted | dashed | wavy"><'text-decoration-style'></a> <a href="css/value_definition_syntax#double_bar" title="Double bar">||</a> <a href="css/text-decoration-color" title="&lt;color&gt;"><'text-decoration-color'></a>

Description  

The text-decoration CSS property is used to set the text formatting to underline, overline, line-through or blink. Underline and overline decorations are positioned under the text, line-through over it.

Text decorations draw across descendant elements. This means that it is not possible to disable on a descendant a text decoration that is specified on one of its ancestors. For example, in the markup <p>This text has <em>some emphasized words</em> in it.</p>, the style rule p { text-decoration: underline; } would cause the entire paragraph to be underlined. The style rule em { text-decoration: none; } would not cause any change; the entire paragraph would still be underlined. However, the rule em { text-decoration: overline; } would cause a second decoration to appear on "some emphasized words".

Browser Compatibility
