Сompile background image with gradient

[z3ndex]

Hi,

when compile background image with gradient like:

background-image: url(../images/ico_search.png), -webkit-linear-gradient(top, #fed02d 0%, #ffb004 100%);
background-image: url(../images/ico_search.png),    -moz-linear-gradient(top, #fed02d 0%, #ffb004 100%);
background-image: url(../images/ico_search.png),     -ms-linear-gradient(top, #fed02d 0%, #ffb004 100%);
background-image: url(../images/ico_search.png),      -o-linear-gradient(top, #fed02d 0%, #ffb004 100%);
background-image: url(../images/ico_search.png),         linear-gradient(top, #fed02d 0%, #ffb004 100%);

at the output I have only the last line:

background-image:url(../images/ico_search.png),linear-gradient(top,#fed02d 0,#ffb004 100%)
