Adding color to Text box in Card

Site URL: https://cbcbellevue.com

Hello!

I have been trying to figure out how to change the color in the text box portion of the image card using CSS to no avail. I tried using my Block id# as well as using the url name before and have even looked at past posts that seemed similar but nothing I did in CSS was registering. Below is the specific page, it is an index page and the index portion I am working on is under anthem-ministry. https://cbcbelleue.com/anthemchurch. I am wanting the color behind the text to change to a different background color, and also hopefully adjust the font color.

Here are a couple ways I tried it based on past results I saw:

(BLOCK ID HERE) .image-background {color: #302958;}

anthem-ministry .image-card-wrapper {
  background: #302958;}

Please help! I should say I also want to change this on just this one card, so it is not something I am wanting to change under site styles.

Thanks!

Can you share link to page where you used text box? I don't see it in above link.

I figured it out based on one of your past responses to someone. Thanks so much for your help!
