I have been spending about 40 minutes trying to get this to work.
In the “Audience Building” card, i want to the photo of the people to go from edge to edge of the div/card and also curve with the div/card at the bottom.
It looks like you have a padding set on the div/card. If so, set Position: Relative & Overflow: Hidden on the div/card, then set Width: 100% and Position: Absolute on the image. Adjust the horizontal & vertical positioning of the image to suit.
