Home Page Content Alignment Issue

I used the AT Accordian Section and connected a page in order to add content to my home page. No matter what changes I make to the text, I cannot get the text to align properly on the page (it is partially cut off). When I look the page in “tablet” or “cell phone” view, it looks fine and is legible. This problem is only in desktop view. Can someone please assist?

Also, I can’t figure out how to change the color of the Subscribe button in the footer widget (Blog Subscription Jetpack).
