text-decoration
The text-decoration property is used for adding different types of lines to text – underline, overline, or line-through (strikethrough).
One standard decoration line
When you add a standard decoration line, you just specify one keyword – underline, overline, or line-through.
selector{
text-decoration: keyword;
}
Multiple decoration lines
You can also add multiple decoration lines specifying more than one keyword. For example, if you want to add an underline and overline at the same time, add both keywords with a space in between.
selector{
text-decoration: underline overline;
}
Add designs to the decoration line
You can also change the design of the decoration line.
For example:
styles: Use one of the keywords: solid (default), double, dotted, dashed, or wavy.
thickness: Use length units or auto.
color: Use color code or keyword.
You can specify all parameters using one line code like in the example below.
selector{
text-decoration: underline double red 2px;
}
<u> and <s> tag
Underline and strikethrough (line-through) can also be implemented directly by HTML. The <u> tag is used to add an underline. The <s> tag is used to add a strikethrough (line-through).
