How to Use Internal CSS

Internal CSS in HTML means adding CSS code in the <head> section of the document. Styling changes apply to every specific element found in the file.

Tip: this is a solid option for one-page websites or when you cannot create external stylesheets for your project.

Look at this example to see how to add the <style> element containing CSS rules for all the page:

      h1 {
         color: red;
         margin-left: 20px;

      p {
         color: blue;

Internal styles are relevant to one page only. However, transferring the same <style> element to other pages is not an efficient practice for adding CSS to HTML documents.

Note: developers add styles in HTML by using internal stylesheets when they are creating templates for their clients or colleagues.

Internal CSS: Summary

  • By applying a style in HTML internally, you cannot reference this stylesheet with the <link> element.
  • Include CSS in HTML so it would be convenient to change and update content. Internal stylesheets can make website maintenance more challenging.
  • The best option is adding CSS to HTML externally. It means you create a .css file and link it to your website.
