navbars grows height automatically on page refresh

Expected behavior

The navbar should remain of the same size after page first time load or reload

Actual behavior

This is the simple code used for the navbar. There is a footer code from the sample below it. nothing else. What is happening in the width of the navbar changes and becomes big when the page is reloaded multiple times. It generally happens when the page is loaded first time sometime. If the page is resized, the navbar size resets to the original. But if again refreshed for 2 or 3 times then the navbar grows in size. It's like a toggle, every time to u refresh the page the size of the navbar changes. Please help!
