Please Help….Widget Title Not Changing Color

Hello and thanks alot for your plugin! I have implemented this plugin in my singlepost.php template and its working great but I cannot change the color of the widget title even when i modify the CSS. I understand your plugin uses the h3 attribute..is there any way to change that? Below is the css i modified

`h3.srp-widget-title{
display: block;
margin: 0;
padding: 8px;
font-family: “Droid Sans”,Helvetica,Arial,sans-serif;
font-size: 1.35em;
color: white;
font-weight: 700;
line-height: 1.35em;
}

Would love some help in figuring this out
