Tell us what’s happening: Add another repeating gradient to this building; make it the same as the one you just added, except don’t add the 90deg direction and use your window color instead of the two transparent colors.
I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
some of your dashes are not the expected type.
Please use an English United States keyboard to make sure your dashes are the correct type. (the first two lines need to be fixed, so you can copy the dashes from the bottom two lines also)
