title: Is it right to use two or more different front-end frameworks in a single web app?
body: <p>i'm starting to learn about web development, by now i'm learning some front-end skills, by now i'm trying to use frameworks like Bootstrap, Foundation, Semantic UI, etc... but i've got a question, is it possible to use two frameworks for a single app? if so, is it worth? if not, Why?</p>
  
  <p>Another question about frameworks i have is: Is it good-practice to use a framework to build the front-end of a web app? if not, why? what's the best-practice method to build the front-end? </p>
