Question 4

Which Bootstrap card sub-component places an image so it seamlessly connects with the top edge of the card?

Accepted Answer

card-img-top

`card-img-top` rounds the top corners of an image to match the card border, creating a flush visual connection at the card's top edge.

Question 5

What does the Bootstrap class `sticky-top` do?

Sticks the element to the top of its scroll container once it reaches that position
