CSS (Cascading Style Sheets) is a markup language used to control the layout and style of web pages.

However, in actual development, we sometimes encounter the problem of CSS loading failure, which may cause the web page style to be disordered or unable to be displayed.

<link rel="stylesheet" href="styles/style.css">
If the styles folder is not in the same directory as the current HTML file, then CSS loading will fail. You can solve this problem by using relative or absolute paths.
