portfolio background repeat

in the portfolio icon
the style is
background: url('url to icon') center center !important;
adding the important flag makes it ignores the
background-repeat: no-repeat;
in .nimble-portfolio-template-3colround .nimble-portfolio-item
please make it like this:
background: url('url to icon') center center no-repeat !important;
an example of what’s going on can be found in my blog
