HTML cancel underlining: How to create underline-free links

Whether it is in web design or daily web browsing, there are often scenarios where it is necessary to create underline-free links. Underlining is often used to indicate links, but can sometimes hinder the overall aesthetics and reading experience of the text. So, how to cancel the underline in HTML? Next, we will explain and answer this question.

First introduction to underline

In HTML, underline is a relatively common mark, and it is also a link representation method recommended in the W3C standard. We usually create underlined links in web pages in the following way:

<a href="#">这是一个带下划线的链接</a>

In this link, the tag <a> defines a hyperlink, and the attribute href specifies the URL address of the link target. The text "This is an underlined link" in the <a> tag is the link text we see, and the underline indicates that this is an accessible link. Clicked link.

How to cancel the underline

So, what if we want to cancel the underline without hindering the link effect? Let’s introduce several implementation methods:

1. Using style sheets (CSS)

First, you can remove link underlines through CSS style sheets. We can set the text-decoration:none; attribute value to the <a> tag in the CSS file to remove the link underline. For example:

a {
  text-decoration: none;
}

Embed this CSS code into an HTML page to remove underlines from all links within the entire page. Of course, you can also choose to use the <style> tag within the HTML page to set the style of a single link. For example:

<style>
  a.custom-link {
    text-decoration: none;
  }
</style>
<a href="#" class="custom-link">这是一个没有下划线的链接</a>

In this example, we set the link style with the class attribute of custom-link, which will remove the underline. The purpose of using this style tag is to use this style only on this link without affecting other links.

2. Use the "text-decoration" attribute (text-decoration)

You can also remove underlines by using the text-decoration attribute. Similar to how CSS is used, adding the text-decoration: none; attribute to the <a> tag can also achieve the effect of removing underlines. For example:

<a href="#" style="text-decoration: none;">这也是一个没有下划线的链接</a>

However, it should be noted that in HTML, using this attribute directly is not recommended, but should be used in CSS files or <style> tags. The advantage of this approach is that you can easily override the default link style on a single link without having to modify the style of all links.

3. Use pseudo-classes (:link and :visited)

In addition to the above two methods, HTML also provides the <a> tag The pseudo-classes <a>:link and <a>:visited can be used to control the initial state and post-visited state of the link respectively. In these pseudo-class attributes, control options for underline disappearance are provided. For example:

a:link, a:visited {
  text-decoration: none;
}

In this example, a:link represents the default style when creating a link, a:visited represents the style after the user visits the link, both Underlines are removed via the text-decoration: none; attribute value. This style can be set in a CSS file as the default style, or for individual links via the <style> tag.

Summary

Removing link underlining is a small trick in front-end development, but it can quickly improve the aesthetics of the web page and make it easier for users to read. In HTML, we can remove link underlines through CSS style sheets, text-decoration attributes, pseudo-classes, etc. No matter which approach is taken, we should ensure that the code is readable, maintainable and compliant with W3C standards.
