我尝试将列表均匀地垂直拆分为2个单独的列并继续编号。我正在使用content: counter()counter-resetcounter-increment。计数器确实从下一个数字开始,但不会继续计数,但重复重复相同的数字。



ol.rectangle-list {
  counter-reset: li;
  list-style: none;
  *list-style: decimal;
  font: 15px 'trebuchet MS', 'lucida sans';
  padding: 0;
  margin-bottom: 4em;
  text-shadow: 0 1px 0 rgba(255, 255, 255, .5);
}

ol.rectangle-list ol {
  margin: 0 0 0 2em;
  /* Add some left margin for inner lists */
}

.rectangle-list a {
  position: relative;
  display: block;
  padding: .4em .4em .4em .8em;
  *padding: .4em;
  margin: .5em 0 .5em 2.5em;
  background: #ddd;
  color: #444;
  text-decoration: none;
  transition: all .3s ease-out;
}

.rectangle-list a:hover {
  background: #eee;
}

.rectangle-list a:before {
  content: counter(li);
  counter-increment: li;
  position: absolute;
  left: -2.5em;
  top: 50%;
  margin-top: -1em;
  background: #fa8072;
  height: 2em;
  width: 2em;
  line-height: 2em;
  text-align: center;
  font-weight: bold;
}

.rectangle-list.start-4 a:before {
  counter-reset: li 3;
  content: counter(li);
  counter-increment: li;
  position: absolute;
  left: -2.5em;
  top: 50%;
  margin-top: -1em;
  background: #fa8072;
  height: 2em;
  width: 2em;
  line-height: 2em;
  text-align: center;
  font-weight: bold;
}

.rectangle-list a:after {
  position: absolute;
  content: '';
  border: .5em solid transparent;
  left: -1em;
  top: 50%;
  margin-top: -.5em;
  transition: all .3s ease-out;
}

.rectangle-list a:hover:after {
  left: -.5em;
  border-left-color: #fa8072;

您在显示计数器的元素上有counter-reset。您需要从伪元素中删除counter-reset并将其应用于父元素。

ol.rectangle-list {
  counter-reset: li;
  list-style: none;
  *list-style: decimal;
  font: 15px 'trebuchet MS', 'lucida sans';
  padding: 0;
  margin-bottom: 4em;
  text-shadow: 0 1px 0 rgba(255, 255, 255, .5);
}

ol.rectangle-list ol {
  margin: 0 0 0 2em;
  /* Add some left margin for inner lists */
}

.rectangle-list a {
  position: relative;
  display: block;
  padding: .4em .4em .4em .8em;
  *padding: .4em;
  margin: .5em 0 .5em 2.5em;
  background: #ddd;
  color: #444;
  text-decoration: none;
  transition: all .3s ease-out;
}

.rectangle-list a:hover {
  background: #eee;
}

.rectangle-list a:before {
  content: counter(li);
  counter-increment: li;
  position: absolute;
  left: -2.5em;
  top: 50%;
  margin-top: -1em;
  background: #fa8072;
  height: 2em;
  width: 2em;
  line-height: 2em;
  text-align: center;
  font-weight: bold;
}

.rectangle-list.start-4 a:before {
  /* counter-reset: li 3; */
  content: counter(li);
  counter-increment: li;
  position: absolute;
  left: -2.5em;
  top: 50%;
  margin-top: -1em;
  background: #fa8072;
  height: 2em;
  width: 2em;
  line-height: 2em;
  text-align: center;
  font-weight: bold;
}

.rectangle-list.start-4 {
  counter-reset: li 3;
}

.rectangle-list a:after {
  position: absolute;
  content: '';
  border: .5em solid transparent;
  left: -1em;
  top: 50%;
  margin-top: -.5em;
  transition: all .3s ease-out;
}

.rectangle-list a:hover:after {
  left: -.5em;
  border-left-color: #fa8072;

目前,您正在重置每个新元素的计数器。因此,每次出现新的a-tag时,计数器将再次显示相同的数字。

请尝试仅在ol元素处重置计数器。
