I’ve tried several times to complete this step, but each time it shows the same hint : " You should give .fb6 a second repeating-linear-gradient in the background property."
You have a background-image attribute, when I think it should be background. Also (as per instructions), your second repeating-linear-gradient should be identical to the first except for removing 90deg and changing the two transparent values to your window variable.
I tried background-image because background wasn’t working I also tried to not use the shorthand property and ended up with the same result, still not working. Thanks a lot tho !
