i like to call these cards

Hello! I have a few suggestions to help:

• Try using the hover attribute to your class dropdown, like this:

.dropdown:hover{
  cursor: pointer;
}

This will indicate that the element can be clicked.

• For the box-shadow you can make it blend better and give it less of a 3D effect by playing with the spread radius, blur radius and the color oppacity of the shadow. like this:

  box-shadow: 5px 5px 30px 5px rgba(0,0,0,0.2) try it out and see if you like the result. You can find more information about box-shadow and it's properties here box-shadow.

Great work! Keep it up.
