title: Toggleable sidebar with bootstrap 4
body: <p>I am Trying to find out the "correct"(best practice) way of creating toggleable sidebar with bootstrap 4. Gone through the examples on the internet and not so sure if those were so good...so If someone can send me related resource links ,it would be great so that I can analyze it.</p>
  
  <p>-I am from android platform so I'm a newbie when it comes to web development but I'm trying to achieve that kind of sidebar like on this side: <a href="https://thenewboston.com/index.php" rel="nofollow noreferrer">link</a>  -notice: sidebar doesn't change its width(stretching) while changeing the size of a browser -until a point when it jumps over to icons width.</p>
