Nav bar & Safari

Hello Masters of 1’s and 0’s,

I have tested the site on chrome, firefox, and safari on a laptop, mobile, and iPad. Everything looks good except for two issues.

First one is only in Safari and only on my iPad. When I come to the home page, the menu is below the screen rather than at the bottom like in Chrome and Firefox. I have to scroll down to see the menu. Happens both in portrait or landscape.

Second issue is that I don’t like how the menu bar scrolls up on my iPhone. How can I get the menu bar to sticky into place when scrolling down like it does on the tablets or desktop browsers?

Thank you!
