TL;DR — The internal CSS styling option is popular for applying properties to individual pages by wrapping all styles in the <style> element. Then, you place it in the <head> section of HTML documents.
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.
