you can just set the background color to any color you like and use the opactity css-propterty.
for example:
.center {
background-color: blue;
opacity: 20%;
}

another solution might be to use rgba for your background-color:

I tried that way too but it gives me “/ running test
The value of the background-color property should be set to transparent.
// tests completed” when I click RUN THE TESTS.

After some googling found the answer, to make the background color transparent.
“background-color: transparent;”
I was with the intention that the it should be “opacity:”
but I was wrong.
