I need to create a faq site for one of our mobile apps. i only need to create a mobile site.
Q: How long is a piece of string?
A: As long as it needs to be.
There is no one size fits all anymore. Don't use Muse. It's end of life anyway. Use Dreamweaver and build your FAQ page with Bootstrap's mobile-first, responsive framework. At least that way you will be certain that your page is usable on xs, sm, md, lg, xlg, portrait and landscape devices.
In Dreamweaver, go to File > New > Starter Templates.
Pick a Bootstrap layout and hit the Create button. See screenshot.
