title: CSS: php messing up template css due to css link
body: <p>My php page styling is done but when I added it to my existing html template ( which has header and left menu ) I noticed that template css menu is messed up. </p>
  
  <p>While debugging what part of styling is causing an issue, I realized its due to bootstrap.min.css which I used while referring to w3schools <a href="https://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_progressbar6&amp;stacked=h" rel="nofollow noreferrer">BootStrap Progress Bar</a>:</p>
  
  <pre><code> &lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"&gt;   
  </code></pre>
  
  <p>Any pointers on how to avoid this? I thought of adding a wrapping container for code but not sure how to make the change. Any suggestions?</p>
