WB21 - best way to change style at runtime

Hi,

I have a site for employees where they can see their work schedule and some other things. The site is used by different companies, but it is not a public site. It's installed local at each clients site.

I want this site to appear in the company colors, so I have to change the style . Company1 in red and company2 in blue. Also some clients want to see their own logo. Of course I do not want to do this in WB, but at runtime.

I am a bit new to WB, so what are my options for this?
