I see the ribbon and text settings, but somehow I'm missing how to change the calendar frame from the default aqua color.
There isn't a specific setting on the widget that lets you change those colors.
However, there is a CSS Url field you can use to host your own CSS file and override any style/color you want. This is a bit more involved, particularly if you're unfamiliar with CSS. Do you have any experience with the CSS standard?
Thanks so much for answering my question. I am familiar with CSS so I will look into that. I am using the Wix website builder and will have to see if the CSS file is a possibility with their templates.
