The HTML base tag is used to specify a base URI, or URL, for relative links. This URL will be the base URL for every link on the page and will be prefixed before each of them. For example, if the URL specified by the base tag is “www.xyz.com” then every other URL on the page will be prefixed by, “www.xyz.com/”.
- The base tag must be defined between the head tags.
- There can be a maximum of only 1 base tag in a page.
<base href = "SAMPLE_URL">
Example: Notice that we have only specified a relative address for the image. Since we have specified a base URL in the head section, the browser will look for the image at “https://media.geeksforgeeks.org/wp-content/uploads/1-95.jpg”. That is in the below program we have specified a base URL “https://media.geeksforgeeks.org/wp-content/uploads/” for all the links and when we are referring to the image at URL “1-95.jpg” then the browser is actually rendering the image from “https://media.geeksforgeeks.org/wp-content/uploads/1-95.jpg”.
