Banner causing side scroll


I’ve added a banner into my site to display some text on a slow scroll, which works ok. However when previewing the site I am able to side scroll, which shows a lot of blank space. I’ve tried the overflow option, however this just cuts the words that overlap the edge of the page off.

If someone can let me know what would fix this, that would be great!
