Inline CSS
An inline style may be used to apply a unique style for a single element.
To use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property.
Example
<!DOCTYPE html>
<html>
<body>
<h1 style="color:blue;text-align:center;">This
is a heading</h1>
<p style="color:red;">This is a paragraph.</p>
</body>
</html>
Tip: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly.
