elements that can use referrerPolicy attribute

reffer_policy.md

The referrerPolicy attribute can be used on any element that makes network requests. Here are the main ones:

1. Link elements:

<a href="..." referrerPolicy="no-referrer">Link</a>
<link rel="stylesheet" href="..." referrerPolicy="no-referrer">

2. Media elements:

<img src="..." referrerPolicy="no-referrer">
<video src="..." referrerPolicy="no-referrer">
<audio src="..." referrerPolicy="no-referrer">

3. Embeds/iframes:

<iframe src="..." referrerPolicy="no-referrer">
<embed src="..." referrerPolicy="no-referrer">
<object data="..." referrerPolicy="no-referrer">

4. Resource fetching:

<script src="..." referrerPolicy="no-referrer">
<source src="..." referrerPolicy="no-referrer">

You can also set a global referrer policy for all requests using a meta tag:

<meta name="referrer" content="no-referrer">

The available policy values are:

• no-referrer
• no-referrer-when-downgrade (default)
• origin
• origin-when-cross-origin
• same-origin
• strict-origin
• strict-origin-when-cross-origin
• unsafe-url

Most commonly you'll see this used on images and iframes for privacy/security reasons.
