Learn CSS Variables by Building a City Skyline - Step 77

HTML-CSS

My code isn’t working, giving me the hint of " You should use a second color of transparent from 10% to 15% ."

code i’m working with :
.fb1c {
width: 100%;
height: 80%;
background: repeating-linear-gradient(
90deg,
var(–building-color4) 0%,
var(–building-color4) 10%,
transparent 10%
transparent 15%,
)
}

Add a comma after the first ‘transparent 10%’, delete the comma after the second "transparent 15%, add the semi-colon after the closing parenthesis, and check that you added properly two dashes before words “building” (I can not see them here).
