How to remove the underline of a tag in css (two methods)

CSS is a language used for web page style design. Various style effects of web pages can be customized through CSS. In web design, the a tag is often used to represent a hyperlink. Although the a tag itself does not generate underlines, some browsers will add underlines by default, which affects the aesthetics. So how to remove the underline of the a tag?

There are two ways to remove the underline of the a tag.

The first method is to remove the underline by setting the CSS style. In CSS, the a tag has an attribute called text-decoration, which can control the underline style of the a tag. To remove the underline, just set this property to none. The sample code is as follows:

a {
    text-decoration: none;
}

This CSS style will be applied to all a tags, thus removing the underline of all a tags. If you only need to remove the underline of a specific a tag, you can add a class name to the tag, and then set the style for the class. The sample code is as follows:

<a href="#" class="no-underline">去掉下划线</a>

.no-underline {
    text-decoration: none;
}

The second method is to use pseudo classes. In CSS, there is a concept called pseudo-class, which can be used to style an element in a specific state. We can set a pseudo-class for the a tag to remove the underline when the mouse is hovering. The sample code is as follows:

a:hover {
    text-decoration: none;
}

This CSS style will take effect when the mouse hovers over the a tag, removing the underline of the a tag. This method is only suitable for removing underlines when the mouse is hovering, rather than removing underlines all the time.

In addition to the above two methods, there are other methods to remove the underline of the a tag, such as using JavaScript to dynamically set the style. However, the above two methods are sufficient to meet the needs of most situations, and are simple and convenient to use, making them the most commonly used methods.

In short, using CSS styles or pseudo-classes can easily remove the underline of the a tag and improve the beauty and readability of the web page.
