Title: linear-gradient top, bottom

Got:

Syntax error: Not a valid color stop: Sass::Script::String: bottom
on line 84 of /Users/fredrik/Code/sass-framework/ospo/scss/demo/../css3-sass-mixins/_all.sass, in `linear-gradient'
from line 46 of /Users/fredrik/Code/sass-framework/ospo/scss/plugins/_header.scss, in `header-search-input'
from line 375 of /Users/fredrik/Code/sass-framework/ospo/scss/site.scss

Fixed it by removing comma separated top, bottom in linear-gradient - fixed it.
