CSS Redesign and UI/UX considerations

[cicdguy]

What happened?

Wide margins everywhere seem to take up space and do not look visually appealing. This also results in accommodating other elements of the catalog (like plugins etc) to have their own CSS definitions to adjust for changes (like Giscus in #27)

Relevant log output

The wide sidebar margin seems wasteful, since no real content is available on the far left of the margin.

Also scrolling right to actually see content on a 1280x800 screen resolution seems inefficient. The content should justify on my screen without me having to scroll left and right, which feels unnatural.
