Header covers search bar component

[agarcia-caicedo]

What happened:
The header covers the search bar component, so the search bar cannot be seen.

What should have happened:

The search bar should be under the header

How to reproduce it (as precise as possible):
Running Telescope as usual and then going to the search page, either through clicking the search button in the header, or by url

Anything else we need to know?:

This is a result of the header position being fixed. Any fixes should aim to keep the position fixed, as it allows the header to always be available for the user.

Environment:

• OS: Windows 10
