Several questions for newly bought theme

First of all, thanks for the great work you’ve done with this template. It’s one of the best I’ve tried and even worked with.

I have several questions, as I’m new to how this template works.

1. Layerslider (Like on the demo version)

I’d like to set up my (Home/frontpage) just like the demo version, but can’t seem to find a way or place to insert my Layerslider “shortcode”.

2. Center Logo in header

I’ve seen earlier there have been a post about this, but I can’t find the place where to configuere the CSS code, so I can center the logo in the header.
In other templates I’ve had there was an option inside the WP to change css codes.

3. Rounded corners (only in the top of the header)

The idea is something similar to the picture inserted below, but not nessesary to have on all 4 corners.. Just the to in the top.

Looking forward to hear from you.
