Псевдоэлемент не виден при использовании переполнения

1 голос
/ 26 июня 2019

Я пытаюсь создать вертикальную черту внутри переполненного элемента, используя псевдоэлемент before: 

.comments:before {
  width: 3px;
  top: -20px;
  bottom: -20px;
  background: rgba(0,0,0,0.1);
}

Проблема, как вы можете видеть в демонстрационной версии, заключается в том, что вертикальная полоса создается только ввидимая часть div.Ожидаемый результат - вертикальная черта во всем элементе div, даже в скрытой части. 

.comments {
  overflow: auto;
  height: 200px;
}

.comment {
  overflow: hidden;
  padding: 0 0 1em;
  margin: 0 0 1em;
  *zoom: 1;
}

.comment-img {
  float: left;
  margin-right: 33px;
  border-radius: 5px;
  overflow: hidden;
}

.comment-img img {
  display: block;
}

.comment-body {
  overflow: hidden;
}

.comment .text {
  padding: 10px;
  border: 1px solid #e5e5e5;
  border-radius: 5px;
  background: #fff;
}

.comment .text p:last-child {
  margin: 0;
}

.comment .attribution {
  margin: 0.5em 0 0;
  font-size: 14px;
  color: #666;
}

Вы можете иметь элемент wrapper для элемента comments и применить к этому элементу вертикальную черту псевдоэлемент . Теперь вы можете сделать высоту вертикальной полосы и секции comments равными, сделав элемент wrapper flexbox (по умолчанию align-items: stretch сделает высоту равной).

См. Демонстрационный пример ниже (изменения отмечены в строке): 

.comments {
  overflow: auto;
  height: 200px;
}

.comment {
  overflow: hidden;
  padding: 0 0 1em;
  margin: 0 0 1em;
  *zoom: 1;
}

.comment-img {
  float: left;
  margin-right: 33px;
  border-radius: 5px;
  overflow: hidden;
}

.comment-img img {
  display: block;
}

.comment-body {
  overflow: hidden;
}

.comment .text {
  padding: 10px;
  border: 1px solid #e5e5e5;
  border-radius: 5px;
  background: #fff;
}

.comment .text p:last-child {
  margin: 0;
}

.comment .attribution {
  margin: 0.5em 0 0;
  font-size: 14px;
  color: #666;
}
