Navbar needs to be fixed and stylized

**Is your feature request related to a problem? Please describe.**
Your navbar looks awful. There is wrong font size selection which makes Meet and Pets to show in different lines. Also css of select language box is just basic html.

**Describe the solution you'd like**
I can provide a professional yet stylized navbar according to the pet app.

**Describe alternatives you've considered**
Stylized alternative for Select language box
