Вопрос:

У меня есть HTML-таблица с липким заголовком, где свойство sticky задается для th элементов.

Я хочу применить a box-shadow с размытием, но это приводит к тому, что тень просачивается / кровоточит по бокам каждого элемента.

Я создал CodePen, который демонстрирует проблему, и где желаемая тень видна под элементами.

Я попытался добавить параметр spread as box-shadow: 0px 5px 7px rgba(9, 30, 66, 0.08); , который решит проблему с боковыми тенями, но вместо этого тени отделяются друг от друга под ними.

Возможно ли создать a, который направлен только в направлении вниз и не связан с тенями родственных окон? box-shadow

Ответ №1:

Поскольку применить position: sticky; к or невозможно thead tr , лучше всего было бы подделать элементы box-shadow on th , используя абсолютно позиционированный псевдоэлемент linear-gradient . Вот пример:

 table {
  text-align: left;
  position: relative;
  border-collapse: collapse; 
}

th, td {
  padding: 0.25rem;
}


th {
  background: white;
  position: sticky;
  top: 0;
}

th::after {
  content: '';
  position: absolute;
  bottom: -6px;
  right: 0;
  left: 0;
  height: 6px;
  background: linear-gradient(rgba(0, 0, 0, 0.15), rgba(0, 0, 0, 0));
}

1. Очень умно, это отлично работает, спасибо! В итоге я добавил to bottom в качестве параметра линейный градиент, чтобы избавиться от острого края, который может возникнуть в противном случае! Точно так же, как это: background: linear-gradient(to bottom, rgba(9, 30, 66, 0.08), rgba(0, 0, 0, 0));
