my custom tabs code not working

I am using the exact code sample given to change the colors of a multi-tab shortcode but it refuses to work 100%.
Here are screen shots of:
1. The example code provided by Shortcodes Ultimate

2. The way I’m copying and pasting in the custom css editor of the plugin with my color choices

3. the shortcode on the actual page

4. what it looks like live

As you can see, I’m following the guidelines but it’s not changing the appearance of the labels. I want it to be #ccea88 but it continues to remain the same default color, #f5f5f5 (or other light grey)

What am I doing wrong or forgetting to code????
