I new to LESS, first using it, but from the start have problem.
I can apply variables at all, here is photo with background-color http://i1367.photobucket.com/albums/r799/Yaroslav_Kuzyo/1_zps9e9436e1.jpg, as you can see Chrome cross background-colour, but if I use #HEX it works. Thanks for the help
