Generated CSS Background Property Missing %

[bradvin]

hey guys - awesome project.

I noticed an issue with the generated CSS for the background property.

example, for XPro2, the generated CSS for the background is:

background: -webkit-radial-gradient(50% 50%, circle closest-corner, rgba(224, 231, 230, 1) 40, rgba(43, 42, 161, 0.6));
background: radial-gradient(50% 50%, circle closest-corner, rgba(224, 231, 230, 1) 40, rgba(43, 42, 161, 0.6));

It should be:

  background: -webkit-radial-gradient(50% 50%, circle closest-corner, rgba(224, 231, 230, 1) 40%, rgba(43, 42, 161, 0.6));
  background: radial-gradient(50% 50%, circle closest-corner, rgba(224, 231, 230, 1) 40%, rgba(43, 42, 161, 0.6));

The % was missing after the 40, which results in invalid css
