3 questions about design!

Hello,

I just got your theme and here is my site : gamescheatshack.com

1- as you see here is your header : https://gyazo.com/3f30e73f608d8203aea5adcf0c8645b0
and here is my header : https://gyazo.com/43b8f8fea903208f972ad3c0a72934b2

my header is very tiny and has something like blue sky makes it unclear ! (i want to make my header that wide as yours)

2- here is that slider in your sample : https://gyazo.com/24fb74415b4168c387a380aeb37667b9

i kept searching for how to make it long time but i failed sadly ! ( i want this slider)

I believe it’s easy but i’m newbie 🙂

Thanks
