你的两个选择是add your own stylesheet 重新定义插件的样式，或通过将样式表出列来完全删除插件的css文件（假设插件通过API正确添加了样式表）

function wpd_my_theme_css() {
    // dequeue plugin css with same handle it is enqueued with
    wp_dequeue_style( \'plugin_css_handle\' );
}
// priority must by a higher number than the css is added on
add_action( \'wp_enqueue_scripts\', \'wpd_my_theme_css\', 9999 );
