Thank you! This wasn’t intentional. Fixed for next patch. To patch it temporarily until we land on an RC you can add this:
add_filter( 'cs_layout_atts', function( $atts ) {
$atts['class'] = ['x-layout'];
if (is_singular() || is_single() ) {
$atts['class'][] = 'x-layout-single';
}
if ( is_archive() ) {
$atts['class'][] = 'x-layout-archive';
}
return $atts;
});
We did a huge refactor under the hood in regards to how routing of different templates works in the context of Stacks, standalone Cornerstone, and the new theme options reboot. Those tco- classes will start showing up with the Theme Options reboot.
