Call out button style and transparency values

[halflifestudios 0]

Hi, I am trying to darken or even change the default color on the Call out action button. I have the transparent theme, and I have added this code to the custom code via other forum answers, but no dice. Is there another way to override a theme's hold on the Call out button color and transparency, etc?

.section-callout .button {
	    background: -moz-linear-gradient(center top , #FFFFFF 0%, #000000 100%) repeat scroll 0 0 transparent;
	}
	

Thanks.

The attribute used in the CSS may only work with Firefox. If you're trying to create a gradient background image effect with transparency, I think it'd be easier to create the gradient image in an image editing program (Photoshop), upload it to the Media Library, and use CSS to apply it as the call out button background image (http://www.w3schools.com/cssref/pr_background-image.asp) and then use the opacity attribute to control its opacity (http://www.w3schools.com/css/css_image_transparency.asp).
