What’s wrong?

Hi add a ; after boder

boder: 2px , solid , black; <== this one 

if you have a property (border) which can take multiply values, they are seperated by spaces, not comma’s, here is an example with place holder values:

border: width style color;

see, spaces, no comma’s

border: 2px solid black;
(If still cannot, press ctrl+0.)
