Hi Wally,

you're just missing the "-" in .main-list (you wrote ".mainlist").

But don't worry, those kinds of things happen all the time.

Blessings from Berlin and happy coding, Nils

Thank you. It was driving me crazy but I did figure it out. And it helped me understand how block, inline and inline-block works even more.

I get it now. First of all I got spelled out the class "main-list" wrong. I forgot the hyphen. I also realized that even though you put the items in the list to display inline-block, the list itself is still displayed as a block element. So you have to change the display to inline-block for the list itself also.

You can write the css like this.

.main-list li { display: inline-block; } .main-list { display: inline-block; }


.main-list li, .main-list { display: inline-block; }

Great, even better you found the solution yourself!
