Пытаюсь выбрать элемент первый по типу используя псевдоэлементы nth-of-type, но не могу понять почему выбираются все элементы? И как правильно написать? Буду рад советам)
CSS
.popast-na-urok .et_pb_blurb_content:nth-of-type(1) .et_pb_main_blurb_image:before{
content:"1";
}
HTML
<div class="popast-na-urok">
