How to remove CSS styles using dw command in Vim

When developing web pages, CSS can provide users with a beautiful graphical interface and a good user experience. However, sometimes we may need to delete and modify some specified styles in CSS. This article will explain how to remove styles in CSS using the “dw” command.

"dw" is a Vim command that means "delete a word". In Vim, a word refers to a continuous sequence of characters consisting of letters, numbers, or underscores. Words can be easily removed using the dw command, including styles declared in CSS. The following are detailed steps on how to use the dw command to delete CSS styles in Vim:

Step 1: Enter the Vim editor

Enter the vim command on the command line to open the Vim editor.

Step 2: Open the required file

vim filename.css

Step 3: Locate the style

Use Vim’s search Function, locate the style that needs to be deleted. Enter the following command on the command line:

/样式名称

where "style name" is the name of the style that needs to be deleted.

Step 4: Delete the style

This command will delete the entire word containing the style name.

Step 5: Save the file

In the Vim editor, use the following command to save the modified file:

:wq

Where "w" refers to "write ”, and “q” refers to “exit”.

In short, using the dw command can easily delete the styles specified in CSS.
