Challenge: Learn CSS Colors by Building a Set of Colored Markers - Step 84

Link to the challenge:

Here is the task.

The black color of your border looks pretty harsh against the more transparent sleeve. You can use an alpha channel to lower the opacity of the black border.

For the border-left shorthand property, use the rgba function to set the color value to pure black with 75% opacity.
