How do increase caption font size

I would like to increase the font size of  image captions 

I inspected the caption element in firefox-see attached screenshot

How do I reference it. Not sure how 'high' into the dom I have to go

It is on this url:

.sqs-block-image .sqs-image-caption p, .sqs-block-image .image-caption p {
    font-size: 24px;
    line-height: 1.68em;
}
