What are the recommended resources for learning about styling links and images in PHP using CSS?

When styling links and images in PHP using CSS, it's important to understand how to properly include CSS stylesheets in your PHP files. One common method is to use the <link> tag in the <head> section of your PHP file to link to an external CSS file. For images, you can use the <img> tag and apply CSS styles directly to the image tag or use classes and IDs to style them.

```php
&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;styles.css&quot;&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;a href=&quot;#&quot; class=&quot;link&quot;&gt;Styled Link&lt;/a&gt;
    &lt;img src=&quot;image.jpg&quot; class=&quot;image&quot;&gt;
&lt;/body&gt;
&lt;/html&gt;
```

In the above code snippet, we have linked an external CSS file named &quot;styles.css&quot; in the &lt;head&gt; section of the HTML file. The link and image elements have been styled using CSS classes &quot;link&quot; and &quot;image&quot; respectively. Make sure to define the styles for these classes in the &quot;styles.css&quot; file to apply the desired styling to the links and images.
