Fixing some troubles!

The elemts of my <nav> worked very well on the mobile version, but on
desktop it was going hard to find and fix the problems. Now the desktop
version works correctly! And the mobile version it's a bit different,
just like I wanted, and keeps working perfectly. Tomorrow I'll add the
text pages and put the links working. I'll probably change the
background or add some opacity to it. I'll put the search box and change
the font-styles, fix some sizes and experience colours.
