Reason of using fixed-top

[justinkruit]

What is the reason we're using fixed-top for the header?
In this case, wouldn't it actually be better to use a sticky position on the header tag itself?

That way we can also immediately replace some stuff like the following:

html,
body,
#page {
  height: 100%;
}

Which results in the #page height not going fully with the page content (this is the #pade div highlighted in devtools):

Have this already on the list, check here https://projekte.crftwrk.de/boilerplate-sample-content/, check the sticky-top navbar and the sticky footer https://projekte.crftwrk.de/boilerplate-sample-content/imprint/.

After the filters PR is merged, I want to open a new v6 branch and go wild.
