please help a brother i am actually stuck my navbar is fixed at the left but still can past all the test.

Hi @sagirgarba,
try this:

in your CSS file

#main-doc{
           margin-left: 200px;
           padding: 0px 10px;
           
       }

Then you have to put in 100% navbar height and
padding-right:50px;

thanks bro. but still 15/16
