Site URL: https://rectangle-mandarin-f3pw.squarespace.com

Hi folks, thanks in advance for any help you can provide. Does anyone have a quick reference for custom CSS to change the font, size and color in the text elements of a banner slideshow?

You can use this CSS

h2.list-item-content__title {
    font-size: 30px !important;
    color: red !important;
}
.list-item-content__description {
    font-size: 20px !important;
    color: green !important;
}
a.list-item-content__button.sqs-block-button-element {
    font-size: 20px !important;
    color: red !important;
}
