Welcome to the community!
This looks to be an issue with the
.cast-studies-title-2 element as shown below:
There is a 425px margin on the left side of that element, so removing that and adding a
text-align: center should give you same effect and solve the overflowing problem.
Edit: As a tip/trick for figuring out trouble elements in the future, if you enable the “X-Ray Mode” by clicking on the icon in the lower left panel (fourth down in that icon list) you’ll be able to see all of your element bounding boxes.
Thank you I will try this now!
