How to centre captions under an image?

How can I centre captions (rather than justify left) underneath an image/image block?Am using the Supply template. Thanks!

Did you ever figure this out? I would also love to know! I figured out how to change the font but not the alignment.

For anyone else looking to do the same, this is the code that worked for me. Paste into Page Header Code Injection (you may not need the font size/line-height bit)

<style>
.sqs-block-image .image-caption p,
.sqs-block-image .sqs-image-caption p {
 font-size: 14px;
 line-height: 1.68em;
 text-align: center;
}
</style>

This is spot on. Thank you. Saved the day!!!

Thank you! Worked well for me too.

This is great! Thank you!
