<s>[INST] How do I style my HTML page using CSS? [/INST] To style an HTML page using CSS, you can use the following steps:

1. Create a CSS file or add a style block in the HTML file.
2. Add CSS selectors and rules to target the HTML elements you want to style.
3. Use CSS properties to set the styles for those elements.

Here is an example:

```
<head>
  <style>
    h1 {
      color: blue;
      text-align: center;
    }
    p {
      font-size: 18px;
      font-family: Arial, sans-serif;
    }
  </style>
</head>
<body>
  <h1>Welcome to my website</h1>
  <p>This is a paragraph on my website.</p>
</body>
```

In the example above, we use CSS selectors `h1` and `p` to target the `<h1>` and `<p>` elements respectively. We then use CSS properties `color`, `text-align`, `font-size`, and `font-family` to set their styles.</s>\ <s>[INST] Is there a way to put the CSS code in a separate file? [/INST]
