How to reference CSS styles in Yii framework?

Yii framework is a high-performance, flexible PHP framework. When developing a website or web application, style sheets (CSS) are a very important part, which can make the website look more beautiful and unified. In the Yii framework, we can reference CSS styles through simple steps and let elements in the web page apply these styles.

Step 1: Create a CSS style file
First, in the Yii framework, we need to create a CSS style file to store our customized styles. Let's say we want to create a styles file called styles.css. We can create a new folder named css in the web directory of the Yii framework and create a styles.css file in it.

Step 2: Edit the CSS style file
Open the styles.css file and write the CSS style you need. For example, we want to set the background color of the web page to red:

body { background-color: red; }

Step 3: Reference the CSS style in the view file
Next, we need to reference the CSS style just created in the view file of the Yii framework document. Taking a view file named index.php as an example, we can reference the style file through the following code in the file header:

In the above code, we use the built-in Html class and BootstrapAsset class of the Yii framework , and our customized style file named AppAsset. Among them,AppAsset::register($this);This line is used to register our style file into the view.

Step 4: Apply CSS styles to elements
Next, we need to apply CSS styles to specific elements in the view file. Taking a specific element as an example, if we want to apply a style to a button, we can write like this:

 'my-button']) ?>

In the above code,'my-button'is what we have in the CSS style sheet A class defined in , used to style buttons. This way, the Yii framework will automatically apply the style to the button when the view is rendered.

Step 5: Refresh the page and see the effect
Finally, we need to refresh the page and see the effect. Open the application, click the corresponding button or visit the corresponding page, and you can see that the CSS style we defined has taken effect.

Summary:
Referencing CSS styles in the Yii framework is very simple, just follow the above steps. In this way, we can easily design a unique look for the website and enhance the user experience. Of course, in addition to CSS styles, the Yii framework also provides a wealth of view components and style classes, allowing for more flexible page design.
