Detailed explanation of CSS underline removal attributes: text-decoration and border-bottom, specific code examples are required

In web design and development, we often need to beautify text styles. A common requirement is to remove underlines from links or text. CSS provides a variety of methods to remove underlines. This article will focus on two commonly used properties: text-decoration and border-bottom, and give specific code examples.

1. Text-decoration attribute

text-decoration is an attribute used to set text lines. It contains many values, including the value for removing underlines. Here are some commonly used text-decoration values:

none: Remove decorative lines from text.
underline: Add underline.
overline: Add decorative lines above the text.
line-through: Add a line in the middle of the text.

To remove underlining from text, we just set text-decoration to none. Here is an example:

a {
  text-decoration: none;
}

Copy after login

In the above code, we set the text-decoration of the a tag to none, thereby removing the underline from the link.

In addition to being applied to links, the text-decoration attribute can also be applied to other elements and selectors, such as text, paragraphs, etc. Just use the corresponding selector with text-decoration: none;

2. border-bottom attribute

The border-bottom attribute is used to set the border at the bottom of the element. We can use this attribute to simulate the effect of removing underlines. Here is an example:

a {
  border-bottom: none;
}

Copy after login

In the above code, we set the border-bottom of the a tag to none, thereby removing the bottom border of the link and achieving the effect of removing the underline.

Similar to the text-decoration attribute, the border-bottom attribute can also be applied to other elements and selectors. Just use the corresponding selector in conjunction with border-bottom: none;.

It should be noted that the application scope of text-decoration and border-bottom properties are not exactly the same. text-decoration can also set other properties, such as color, style, etc., while border-bottom can only be used to set the bottom border.

3. Code Example

The following is a practical application example, showing how to use text-decoration and border-bottom to remove underlines:

<!DOCTYPE html>
<html>
<head>
  <style>
    a {
      text-decoration: none;
      border-bottom: none;
      color: blue;
    }
    
    p {
      text-decoration: underline;
    }
  </style>
</head>
<body>

  <p>This is an example of a paragraph with an underline.</p>
  
  <a href="#">This is a link with an underline</a>

</body>
</html>

Copy after login

In the above code, We use text-decoration: none; and border-bottom: none; to remove underlines from links and paragraphs. At the same time, we also set the text color of the link to blue to increase readability.
