Help me with the theme to save pets from the street

With friends form an NGO, our purpose is to save dogs, cats from the street, sterilize them, etc, without profit.

I loved the SELA theme in particular the @jessiwebb I love https://www.franksfiddles.com, try to do it in the same way but I can not get that result.

Please, I hope someone can help me.

I want my website to be the same as https://www.franksfiddles.com

I want the menu, which goes down next to the web, the menu is not static.
My slider does not work, the slider buttons do not work, and there is a lead line, the image of the slider is not shown in its correct size so it looks blurry.

I hope @jessiwebb can help me for this noble cause, with its theme.
And hopefully someone can help me here I attach an image in case I change the theme (https://ibb.co/hPfGOx)
I have the Super Hero Slider installed just like @jessiwebb
