PureMart is only effective on Virtuemart Component pages. It has no effect in VM Module, because PureMart loads the necessary CSS file to stylize the pages when Virtuemart Component is being used. But you can publish the product module in other pages, right? The puremart CSS file is missing in those pages, therefore you will see original styles for add to cart button (which is green) for add to cart button.
Theoretically PureMart doesn't promise to style VM modules, but you can do this:
Open this CSS file in your server:
www.futbolika.net/templates/rt_fresco/css/template.css
And add these CSS rules to the bottom:
div.vmgroup div.addtocart-area div.addtocart-bar input.addtocart-button {
background: #757472; /* Old browsers */
background: -moz-linear-gradient(top, #757472 0%, #757472 50%, #62615f 50%, #62615f 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#757472), color-stop(50%,#757472), color-stop(50%,#62615f), color-stop(100%,#62615f)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #757472 0%,#757472 50%,#62615f 50%,#62615f 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #757472 0%,#757472 50%,#62615f 50%,#62615f 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, #757472 0%,#757472 50%,#62615f 50%,#62615f 100%); /* IE10+ */
background: linear-gradient(to bottom, #757472 0%,#757472 50%,#62615f 50%,#62615f 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#757472', endColorstr='#62615f',GradientType=0 ); /* IE6-9 */
border:1px solid #828282;
border-color:#828282 #333333 #1d1d1d;
-webkit-box-shadow:0 1px 1px #545454, inset 0 1px 0 #cfcfcf;
-moz-box-shadow:0 1px 1px #545454, inset 0 1px 0 #cfcfcf;
box-shadow:0 1px 1px #545454, inset 0 1px 0 #cfcfcf;
padding:0px 30px 0px 0px;
height:28px;
display:inline-block;
position:relative;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
border-radius: 4px;
}
This CSS lines above will change the "green" add to cart button to "gray" in the VM Product module.
You can play around with this CSS code to change it's style though. You can use
www.colorzilla.com/gradient-editor/ to generate Gradient CSS background colors if you would like other than what comes with PureMart.
