    <h2>Scroll this page to see the effect</h2>
    <h2>The navigation bar will stay at the top of the page while scrolling</h2>

    <p>Some text some text some text some text..</p>
  </div>

</body>

</html>

in the .navbar selector, I have added margin-bottom:200px; why it does not show any effect. why its not placing a gap of 200px between the navbar and contents below it. I am trying to show gap between them and i tried margin-bottom. just wanted to know why its not working. I have provided the code below.

The ```margin``` property doesn't work on ```fixed``` elements. Alternatively, you can give a ```margin-top``` to ```main``` — nimsrules, Sep 05 '20 at 10:05

Because you have a position: fixed rule specified. I replaced you with the position: sticky rule. Your margin-bottom is now working.
