Hey, @amber_christian Welcome to the webflow community, I see only one card please add the other two so that we can help and watch this video if you haven’t already you might get an idea on how to use flex to solve the issue.
Hey, @amber_christian as it was taking time to understand your structure and their respective style It was easier for me to rebuild it from scratch so here is the video of the structure and the styles applied.
One small suggestion it is better to have a minimum text in the summary to make the cards look even better as flexbox items with same width and height is based on the tallest child.
