Thanks

.su-tabs.my-custom-tabs {
background-color: #e8a519;
}

.su-tabs.my-custom-tabs .su-tabs-nav span {
font-size: 1.3em;
}

.su-tabs.my-custom-tabs .su-tabs-nav span.su-tabs-current {
background-color: #ffffff;
}

.su-tabs.my-custom-tabs .su-tabs-pane {
padding: 1em;
font-size: 1.3em;
background-color: #ffffff;
}

Hi,

You can change the tabs color with this Custom CSS:

.su-tabs-nav span.su-tabs-current {
    background: red !important;
}

.su-tabs-nav span {
    background: blue !important;
}

Please add the above CSS to your Child Theme’s style.css or in case you haven’t setup a Child Theme already, then you can also add the CSS to wp-admin -> Appearance -> Customizer -> Additional CSS so you won’t loose the changes after Theme or WordPress updates.

Please let me know how it works.

Best Regards,
Csaba
