Note to reviewers

I found that the menu button for mobile-view doesn't work, should I create a new issue and PR for it?

I just saw your comment @Keshraf, it would be better to fix it in this PR

[Keshraf]

Okay @eddiejaoude, I will fix it in this PR 👍

Welcome @Keshraf! Thank you so much for your first pull request!

[eddiejaoude]

Sorry @Keshraf I just realised we might be talking about different menu buttons. Are you talking about the light/dark mode or the "hamburger" one? If for the existing button that is not required for this PR, sorry I assumed you meant for your new button

Please clarify and we can hopefully get this merged soon, thanks 👍

I was talking about the "hamburger menu" button. Should I add it to this PR?

[eddiejaoude]

Yes please, if you can add it to this PR as it is related to the changes here 👍

Sorry you have some conflicts to resolve now because other PRs have been merged in
