WordPress Gallery Captions

Hello,

I have many picture galleries using the built-in WordPress galleries function from the theme I used before I recently switched to Enfold.

Upon switching, the captions have all been hidden by Enfold. Line 405 in base.css has this code causing the caption to be hidden:

#top .gallery-caption{
display: none;
}

I use a child theme and would like to bring back the captions without having to do anything each time the theme is updated. I discovered that adding the code below to QuickCSS fixes my issue

#top .gallery-caption {
display: block !important;
}

Is this the best way to go about solving the issue?

Thanks!
