changing Font color/style for Slide show titles in hover

Site URL: https://www.roslynfassett.com/african

Hi,

I would like to be able to change the font color or style/size of the titles/descriptions in the slideshow galleries.It is set to Hover Mode. On certain images (like the one attached) the default white font doesn't read very well and my client would like it to be more legible.  As I am not very familiar with custom coding, would anyone be able to tell me how I can change this using the CSS Editor and custom coding? If I can't change the color, I'd at least like to make the text bold or larger. Thank you.

Add to Home > Design > Custom CSS

/* change hover background */
.sqs-gallery-block-slideshow .slide.loaded .meta {
    background: rgba(0,0,0,0.5);
}
/* change font size color */
.sqs-gallery-block-slideshow .slide.loaded .meta * {
    color: red;
    font-size: 1.5em;
}

Thank you so much!
