drobcap

Hello,
I created a class specification and is inserted in css “content-shortcodes.css” with the following code:
.su-dropcap-style-axis {color: #fff; background: rgb (255, 66, 9); / * Old browsers * / background: -moz-linear-gradient (top, rgba (255,66,9,1) 0% rgba (255,0,0,1) 100%); / * FF3.6 + * / background: -webkit-gradient (linear, left top, left bottom, color-stop (0%, rgba (255,66,9,1)), color-stop (100%, rgba (255,0,0,1))); / * Chrome, Safari4 + * / background: -webkit-linear-gradient (top, rgba (255,66,9,1) 0% rgba (255,0,0,1) 100%); / * + Chrome10, Safari5.1 + * / background: -o-linear-gradient (top, rgba (255,66,9,1) 0% rgba (255,0,0,1) 100%); / * Opera 11.10+ * / background: -ms-linear-gradient (top, rgba (255,66,9,1) 0% rgba (255,0,0,1) 100%); / * IE10 + * / background: linear-gradient (to bottom, rgba (255,66,9,1) 0% rgba (255,0,0,1) 100%); / * * W3C / filter: progid: DXImageTransform.Microsoft.gradient (startColorstr = ‘# 45484d’, endColorstr = ‘# 000000’, GradientType = 0); / * IE6-9 * / text-shadow: 0 -1px -1px # 000; -moz-text-shadow: 0 -1px -1px # 000; -webkit-text-shadow: 0 -1px -1px # 000; border-radius: 50%; -moz-border-radius: 50%; -webkit-border-radius: 50%;
}
But the plug-in makes me into the drop down menu and select if I click on “content-shortcodes.css” do not see it (but by ftp in the file is the code).
I tried to put it in “custom css” and then in class (when I insert the shortcode) produces no effect, and I see the following in the source code [class = “out-of-dropcap dropcap-style-default-.su dropcap -style-axes “].
What is wrong?
