CSS Question

make full col-md-2 screen's background color black

This is what I tried to make
This is what happened

I tried to make simple menu , my goal is to make full

col-md-2
screens's background color black (like image - 1) , but when texts/radiobutton/etc. of menu ended , rest of the empty screen of
col-md-2
took body's background color (in image - 2) not my div's background color . though I mentioned my
<div>
's background color after my body's background color separately. Here is my code :

Answer
<!DOCTYPE html>
<html>

  <head>
    <link data-require="bootstrap-css@3.3.6" data-semver="3.3.6" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.css" />
    <style>
      .col-vh {
        background-color: #000;
        height: 100vh;
      }
    </style>
  </head>

  <body>
    <div class="container">
      <div class="row">
        <div class="col-md-2 col-vh">
          Lorem Ipsum
        </div>
      </div>
    </div>
  </body>

</html>

Add 100vh to your column and it should be 100% of the viewport. See this plunker.

Different Approach Work with min-height and height on your body tag. See this Question for details.
