On the website, when I click on the menu button repeatedly, the menu and the navigation highlights completely. On my actual project (not the codepen), this makes the whole hero image + navigation + landing page highlight when you click it in fast progression.
Is there a way to stop the highlight? This can cause some usability issues.

<div class = "mobile-nav-button">☰</div>
problem mostly lies with this div right here.
