Hi, Carol

Thanks for reaching out to us.

At this time, unfortunately, we are still not 100% WCAG/ADA compatible, but we plan to do this in the future.

We can't say an ETA right now, because our priority tasks depend on the number of users who ask for a certain development feature, or an improvement;

but we will do our absolute best to work on becoming completely WCAG/ADA compatible as soon as possible.

If you'd like, you can certainly follow our changeLog page, where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

In regards to using CSS to add custom styles/colors, we can help you with that.

Please try these CSS selectors :

.wpdt-c.wdt-skin-light .wpDataTablesWrapper .dataTables_length .bootstrap-select.length_menu {
   
    background-color: black !important;
}
.wpdt-c .bootstrap-select:not([class*=col-]):not([class*=form-control]):not(.input-group-btn) {
    width: 100%;
    background-color: black !important;
}
.wpdt-c a {
    
    background-color: black !important;
    color: white !important;
}
.wpdt-c .bootstrap-select .bs-searchbox input {
     background-color: black !important;
    color: white !important;
    
}

The last one for the searchbox input i added as optional, if you don't need that one, you can remove it, off course.

If you need this for a specific table, add it to the table's Customize/Custom CSS,

but if you need it for all tables, paste it in main plugin settings/Custom JS and CSS/Custom CSS.

Let me know if this helps, at least while our developers don't complete the accessibility compatibility of our plugin.

Thank you
