Custom Tab Colors

Hi,

I’m trying to customize the tab colors. I reviewed the forum and added this code to the HB CSS section:

.tabcolor1 .vc_tta-color-grey.vc_tta-style-classic .vc_tta-tab>a {
border-color: #f0f0f0;
background-color: #37d883;
color: #666;
}

.tabcolor1 .vc_tta-color-grey.vc_tta-style-classic .vc_tta-tab>a:hover {
background-color: #37d883;
}

I added “tabcolor1” to the “Extra class name” section.

Nothing changed. What am I doing wrong? This is the tab I am referring to.
