Layout suggestions

The entire layout and sizing of the website feels way too large. (on screens that are not high resolution/retina)

It fills the entire screen width for certain device widths (.container-fluid) and the headings chosen for the card-titles are way too large as well, wasting a lot of screen space.

Here an example, for a side-by-side view. This first screenshot is the current website as-is.

And this is a locally modified version (with Chrome DevTools) just to narrow down a lot of things.

(both screenshots capture exactly the same viewport, just from different tabs, no tricking with zoom-levels here 😄 )

What I changed:

• Switched out the .container-fluid that a huge part of the site used, replaced it with just .container instead.
• Replaced all card headings with h3 instead of h2 and all subtitles with h5 instead of h4
• I also adjusted the padding of the TYPO3 logo, just to properly line up the navigation with the container

These are not too significant changes to the site layout, but they already make a huge difference compared to what there was before.
