Red-light theme

Hi everyone! :wave:

I’ve created this theme for my forum and as you can see I like the red color with a light background and a dark header.

I also use this theme with a variable width. Maybe I add some settings to change the width to another value and/or a fix width.
I have added the discourse slider (in red) and the logout button.

I removed the loading slider for now but I will “add” it in the near future again.
