How to remove underline in css

In web design, underlining is a commonly used text decoration method, used to mark links, text boxes and other elements. But sometimes, we need to remove underlines to make the text more concise and clear. In CSS, there are several ways to remove underlines.

1. text-decoration attribute

text-decoration attribute is used to set text decoration, including underline, strikethrough, overline, etc. To remove underlines, just set the text-decoration property to none.

For example:

a {
  text-decoration: none;
}

This will remove the underline of the text link.

2. border-bottom attribute

border-bottom attribute can set the bottom border of the element. When the element is a text link, it can be used to replace the underline.

For example:

a {
  border-bottom: none;
}

In this way, you can remove the underline of the link and use the lower border to achieve your needs.

3. text-decoration-style attribute

text-decoration-style attribute can set the style of text decoration, including solid line, dotted line, double solid line, etc. When set to none, underlines are also removed.

For example:

a {
  text-decoration: underline;
  text-decoration-style: none;
}

This will remove the underline of the link.

4. :hover pseudo-class

In addition to the conventional underline removal method, we can also use the :hover pseudo-class to achieve the effect of removing underlines when the mouse is hovering.

For example:

a:hover {
  text-decoration: none;
}

This will remove the underline of the text link when the mouse is hovering.

Summary

The above are several commonly used CSS methods to remove underlines. In actual development, we can choose the appropriate method according to specific needs. In order to keep the code tidy, it is recommended to define the style without underlining separately to facilitate management.
