How can you change the gallery caption styling

Hi, I've been struggling with this for a while now, I have a gallery page (this also happens in the gallery block) and I want to change the font and size for the image caption... I can't find it anywhere in styling options, I don't mind trying to use custom CSS too because it's very annoying like this!

I'm so sorry😂😂 I started freaking out because I accidentally sent you a paid question on your blog (please ignore that)

And thank you very much for your help!!

.sqs-lightbox-meta h1 {
    color: #fff !important;
    font-size: 20px !important;
    font-family: helvetica !important;
    text-transform: initial;
}

you can use: uppercase, lowercase, capitalize... (initial is default)
