Semi-Styled

Great learnings in there with normalise.css and grid.css.
Strange button background

I'm just about to [start finishing]
(http://teamtreehouse.com/library/websites/build-a-simple-website/stylin
g-content/finishing-the-css) the CSS for the cupcake site.

On Chrome on my Android phone the button only gets the background image
starting 1/2 way across, whereas it looks fine on the desktop browsers
and on Samsung's "Internet" browser on my phone (a Galaxy Note)

See screenshot here: http://screencast.com/t/fu7zuf6fo

Any help appreciated!
