# UNSAFE_ELEMENT: Element that changes the page

> Element that changes the page

| Severity | Fault                         | Stage        |

## What it means

The component creates a &lt;base> element, which rewrites how every relative URL in its shadow root resolves, or a &lt;meta> element, which can refresh or redirect the page (rule unsafe-element).

## How to fix

Write absolute URLs where you need them, and leave the page's head to the site.
