Improve CSS for HTML

[tomschr]

Is your feature request related to a problem? Please describe.

The current look of my HTML pages are a bit... boring. Furthermore, it should be readable on smartphones and desktop PCs.

• improve CSS
• take into account smartphones
• use grid(s) to describe the layout
• use alternative stylesheets?
