Yii framework refers to CSS methods: 1. Inline style, write the CSS style directly on the HTML element in the view file; 2. Internal style sheet, use the style tag in the head tag of the view file. Define CSS styles; 3. External style sheet, create an independent CSS file and reference it using the link tag in the view file.

In the Yii framework, you can use the following methods to reference CSS files:
1. Inline Styles: Write CSS styles directly on HTML elements in the view file . For example:
<div style="color: red;">Hello, Yii!</div>
2. Internal Stylesheet: Use the `
<head>
<style>
.red-text {
color: red;
}
</style>
</head>
<body>
<div class="red-text">Hello, Yii!</div>
</body>3. External Stylesheet: Create a separate CSS file and reference it using the `` tag in the view file. First, create a CSS file such as `styles.css` in a public directory (usually the `web/css` directory). Then, use the following code to reference the CSS file within the `
` tag of the view file:<head>
<link rel="stylesheet" href="/css/styles.css">
</head>
<body>
<div class="red-text">Hello, Yii!</div>
</body>In the above code, `/css/styles.css` is the relative path of the CSS file, you It needs to be adjusted accordingly according to your project structure and file location.
Using external style sheets can separate CSS code from view files, making the code more maintainable and reusable. You can reuse the same style file in different view files, thereby reducing code duplication. Additionally, by placing CSS files in a common directory, style files can be better organized and managed.
The above are several common ways to reference CSS in the Yii framework. Depending on your specific needs and project structure, you can choose the way to reference CSS files that works best for you.
