Google Font Problem

T3 BS3 Blank

I followed the below tutorial to use Google fonts:
http://www.joomlart.com/video-tutorials/t3-framework/add-new-fonts

Identified font in (templates/t3_bs3_blank/less/variables.less)
_____________________________

@font-family-sans-serif: "Raleway", sans-serif;
_____________________________


However, Google font doesn't work...

1) Font changes do not appear on homepage after refresh
2) In assets.xml - code editor recognizes anything before = sign as similar color to version or encoding (ie, not part of file tag)
