Aligning content within site container / grid

Hi there, I’m having a bit of trouble working out how to line up content inside a slider to the websites’s container / grid of 1110px … wondering where I’m going wrong?

So basically need the text & button content inside each of the slides to sit inside the container width of 1110px (as per the rest of the site content – so same as per the homepage header currently displays.

Hope that makes sense, and thanks so much in advance for your help! ??
