Hi there,
you can use the generate_blog_get_column_count
filter to conditionally set column widths:
https://docs.generatepress.com/article/using-columns-in-the-blog/#changing-the-number-of-columns
So you’re PHP Snippet would look like this:
add_filter( 'generate_blog_get_column_count','db_tax_archive_column_count' );
function db_tax_archive_column_count( $count ) {
if ( is_category() || is_tag() ) {
return 33;
}
return $count;
}
For the font size you can use this CSS:
.category h2.entry-title,
.tag h2.entry-title {
font-size: 20px;
}
