You can include the CSS style rules directly in the HTML file, by using the "style" tag within the "head" section of the HTML document.

Here's an example:
``` 
<!DOCTYPE html>
<html>
<head>
  <style>
    /* Your CSS styles go here */
    h1 {
      color: red;
      text-align: center;
    }
  </style>
</head>
<body>
  <!-- Your HTML content goes here -->
  <h1>This is a heading</h1>
</body>
</html>
``` 
In this example, the CSS styles are defined within the "style" tag, and apply to the rest of the HTML document. The h1 selector sets the text color to red and centers the text.

Note that this method of including CSS styles in an HTML document is not recommended for large projects, as it can make the HTML code difficult to maintain. It is generally best to keep your CSS styles in a separate file, and link to it from the HTML document.
