Challenge: Learn CSS Colors by Building a Set of Colored Markers - Step 85

Link to the challenge:

You got the cap and sleeve div elements nested inside marker red div. Now you just need to copy these two divs and paste them inside both the marker green and marker blue so all markers have the same cap and sleeve styling.
