Content in Slider doesn’t fit on Mobile

I have a slider that shows the copy I've written along with a button which I would like to show up on the mobile version of the site. For some reason, the slider content does not adapt to the screen when I look at it on my phone.

The website is the following: www.luckywebsites.ca

Any tips on how to resize the slider for Mobile? If not, how can I make a separate site for the mobile only?
