Image Carousel/Social icons/Mobile verson

Few issues I am running into:

1- Can’t make the image carousel fit the whole width of the page; the right side arrow of the carousel is shifted a couple inches to the left of the page. Can you please tell me a) how to center the images, and b) what is the size of the image so that fits the whole width of the page and is around 3” narrow?
2- Is there a way to have the social icons centered (they appear aligned to the left) and also have them next to the copyright line?
3- How do I create the mobile page? Looks really awful on my phone

Thanks for your help!
