How to create css file

In the development process of modern websites, CSS is an integral part. CSS files can control the styles in web pages, making them look more beautiful and professional. In this article, we will discuss how to create CSS files.

1. Create a new folder
   First, create a new folder on your computer, this will be the directory where you store your CSS files. You can name this folder something like "CSS" or "Style".
2. Create a new text file
   In the newly created folder, right-click on the blank space and select "New Text File". Name the file "style.css". Note that this file must be a file with the suffix ".css". Please make sure that you have installed the corresponding text editor software on your computer, such as Sublime Text, Notepad, etc. I recommend using Sublime Text to facilitate code highlighting and debugging.
3. Writing CSS code
   You can use a text editor to open the "style.css" file and then write CSS code. First, you need to add a comment to identify the purpose of this CSS file. For example:

/ This CSS file is used to control the style of the website /

Immediately afterwards, you can start writing your CSS code. CSS code can control the appearance of all visible elements in an HTML page, including text style, background color, border lines, etc.

Here are some simple styles that you can modify as needed:

body {
font-family: Arial, sans-serif;
background-color: #f2f2f2;
}

h1, h2, h3 {
color: #333;
text-align: center;
}

can be seen from these styles , the format of the CSS code is "selector {property: value;}", the selector defines the HTML element whose style is to be changed, the attribute describes the type of style, and the value is the specific value of the attribute. When writing CSS code, pay attention to the standard use of indentation and semicolons.

4. Link the CSS file to the HTML page
   After you finish editing the CSS code, you need to link the CSS file to the HTML page so that the CSS code can work. To implement this process, we need to add the tag to the HTML page. The specific operation method is as follows:

a. Open the HTML page in your text editor and find the tag.

b. Add the following code in the tag:

Note that the href attribute should point to the path where you save the CSS file. If you have multiple CSS files in the HTML below, you will need to repeat the above process using the tag.

5. Storage of CSS files
   After you finish writing the CSS file, you need to store the CSS file in a specific folder on your computer for management. You can save the files in the same folder as your website's home directory (making it easier for developers to maintain), or store the CSS files independently in a separate folder for future use.

Summary:

The process of creating CSS files mainly includes the following steps:

1. Create a new folder and name it CSS or Style.
2. Create a new text file and name it style.css.
3. Use a text editor such as Sublime Text to write CSS code.
4. Link CSS files into HTML pages.
5. Store CSS files for future use.
