Ask HN: Learning Rails but wanting to launch

As someone learning rails and touching up on HTML, CSS/Frontend I'm super excited to get my product launched but while I am learning, I'm wanting to get a page out to get some interest and ideally some signups.

What would benefit most in terms of perception by the public vs time spent etc.

Bootstrap, a pre-made HTML theme, solutions like Webflow, LaunchRock or other.

Any recommendations? Cheers
