Fix logo and menu on tablet/mobile

Hi all,

I am building a website for a friend of my and I am using the theme Food Express. I have a problem with two things and I don’t know how to fix it.

First problem:
Is it possible to center the logo and the menu under the logo on tablets and smartphones? I don’t think it look nice right now. The logo is on the left and the hamburger menu is on the right, but 30-40 pixels under the logo, that’s weird..

Second problem:
If you look at the homepage, there is a green border under the images with a lot of whitespace. How can I delete this? There is to much whitespace at the bottom and the white line is weird there..

Hope someone can help me with this one.

Thanks!

Kind regards,
Rick
