How to add CSS rules into an HTML document

You can put your CSS rules into an HTML document using the <style> element. This tag is placed inside <head>...</head> tags. Rules defined using this syntax will be applied to all the elements available in the document.

The following is an example:

<!DOCTYPE html>
      <style media = "all">
         body {
            background-color: linen;
         h1 {
            color: maroon;
            margin-left: 40px;
      <h1>This is a heading</h1>
      <p>This is a paragraph.</p>
