How CSS code runs in the browser

CSS code is a method used to control the appearance and layout of web pages style sheet language. In order for the CSS code to take effect in the browser, you need to follow the following steps:

1. Create a style sheet file

Create a file with the extension ".css" , for example "style.css". This file will contain CSS code.

2. Linking style sheet files in HTML

In the <head> section of the HTML file, use < link> Tag link CSS file:

<code class="html"><link rel="stylesheet" href="style.css"></code>

Copy after login

3. Write CSS code

In the CSS file, write the CSS code that specifies the style of the web page element. CSS code consists of selectors (which specify the elements to be affected) and declarations (which specify the properties and values of the elements). For example:

<code class="css">body {
  font-family: sans-serif;
  font-size: 16px;
}

h1 {
  color: red;
  text-align: center;
}</code>

Copy after login

4. The browser parses the CSS code

When the browser loads the HTML file, it parses the <link> tag and loads the linked CSS file. It then parses the CSS code and applies it to the corresponding HTML element.

5. Web pages render as expected

The browser renders web pages based on the applied CSS code, thereby controlling the appearance and layout of elements.

Other notes:

You can embed CSS code into the <style> tag and place it directly in the HTML file . However, it is generally recommended to use external stylesheet files to keep your code organized and maintainable.
The order of CSS code is important. Rules written later will overwrite rules written earlier.
Use browser developer tools such as Chrome DevTools to view and debug CSS code.
