How can I display all collections in a row using the Dawn theme?

Hi everyone! Is there a way that I can make the collage section in the dawn template show all three collections in one row instead of how it is defaulted. Right now its like this:


but I kind of want them all to be next to each other and the same length. I don’t know if this is possible. Thank you in advance to anyone who can help me out! Also, is there a way that to center the featured collection’s header on the dawn template?

HI @ajulia
In this case I think you can use the section Collection list.
