Step 20 in CSS Flexbox

I can’t get past Step 20 in the Flexbox project. This is my code:

@media (max-width: 800px)

#gallery img {

width: 50%

}

It keeps telling me to key exactly what I have here as if I didn’t. I have read that its a bug, but that only seems to be from extraneous articles/elements/etc., which I clearly haven’t added.

I’ve edited your post 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.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

Thank you for formatting my question. Can you happen to help with my issue on Step 20? Any insight would be greatly appreciated.
