Using External Resources

When you develop web pages with HTML, you often need to link to external resources. For example, we usually keep our CSS and JavaScript codes in separate files.

Adding external CSS files

Suppose your CSS codes are in an "index.css" file. You use the <link> tag to link that file to your HTML code. We place this <link> tag inside the <head> tag.

With the <link> tag, we use the rel attribute to define the relationship of the external file and the href attribute to assign the external file path.

Here is the code we use for that:

html

index.html

index.css

Adding external Javascript files

When we want to add external Javascript files to our HTML web page, we use the <script> tag with the src attribute.

html

index.html

index.js
