In the process of website development, we often need to add, modify, and delete CSS styles. I believe everyone already has a certain understanding of additions and modifications. But when it comes to deletion, some people may not be skilled enough. This article will share some simple methods for deleting CSS styles to help you process styles more efficiently.

1. Directly delete the content in the CSS file

This is the most direct method and the easiest to understand. Find the style code that needs to be deleted in the CSS file and delete it. The advantage of this is that you can delete all related styles at once, but it should be noted that if other files reference these styles, these references also need to be modified accordingly.

2. Use browser developer tools

Most browsers come with developer tools, through which we can view and modify various parts of the web page, including CSS styles. Here, we can view all the rules in its style sheet by selecting the corresponding element. Then find the rule you want to delete, right-click it, and select "Delete".

3. Use style override

In CSS, the latter style with the same name will overwrite the former. Therefore, we can add a style with the same name to the stylesheet, but set its attribute value to "none". In this way, the style will be overwritten and deleted. It should be noted that this method is only suitable for situations where there are relatively few style attributes that need to be overridden, otherwise the code will be lengthy and difficult to maintain.

4. Use the !important keyword

In CSS, you can use the !important keyword to force priority. It can be used in a style anywhere, overriding all other styles. Therefore, we can add a style with the same name to the style rule that needs to be deleted, and add "!important" after its attribute value. In this way, the styles that need to be deleted can be overwritten. However, this method can also make the code verbose and difficult to maintain, and it is recommended to only use it when necessary.

The above are some simple CSS style deletion methods. It should be noted that before deleting a style, you must carefully confirm whether the deleted content is correct. Of course, if you are not sure what you want to delete, it is best to back up your style files to avoid unnecessary losses.

In general, although style deletion is simple, you must consider whether deletion will affect the styles of other parts and ease of maintenance. I hope everyone can use these methods to better complete website development work.
