Add Unique Styles to Your Page Using Internal CSS

Internal CSS: Main Tips

• You can integrate internal CSS stylesheets by placing the <style> element in the <head> section of a page.
• Internal styles apply to whole pages but not to multiple HTML documents.
• Several pages can be styled by repeating the same block of internal styles in them.

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:

<head>
   <style>
      h1 {
         color: red;
         margin-left: 20px;
      }

      p {
         color: blue;
      }
   </style>
</head>

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.
