The <base> tag can be used to alter all the links and images on the page. It also adds the ability to specify a default target for links.

For example:

<html>
<head>
  <base href="https://example.com/" target="_blank">
</head>

<body>
  <a href="my-page">This opens example.com/my-page in a new tab.</a>
  <img src="my-image.gif" alt="This loads example.com/my-image.gif">
</body>
</html>
