I want to modify the navbar, specifically enlarging the size of the navbar. How can I do that? please help

Hi,

You can modify the css in sites/default/themes/default/general.less

Hi, thanks for the reply. I've tried editing the general.less in the less folder but there's no change whatsoever to the page after I edited it

Never mind, I got it. There's no change because I copied the default folder to other name and modified the general.less in that new folder. I succeeded in modifying the page when I modified the general.less in the default folder.
