Hey Oliver,

I see two typos in you code.

The first on is in the CSS. In your #gallery li, you have a comma instead of a period in 28.3333%

Second is in your HTML. For your section ID of secondary, you have the equal sign and quotation mark backwards.

Fix those and it should work.

Keep Coding! :)
