Bootstrap is a very popular platform and is widely used for building websites.
Take some time to check out Bootstrap's components (it's basically a pattern library on steroids)
Many designers complain that bootstrap's popularity makes all websites look the same -- but other designers point out that you can customize the code for a different look. Check the code on websites (you should be able to see "bootstrap") and find:
an example of a typical bootstrap site
a site that uses customized bootstrap for a unique look
