在列数中使用分隔符

Question

我想在使用CSS的列数时在每列中使用分隔符。

HTML：

<ul class="channel_list">
    <li><input class="channels" type="checkbox" name="7" value="y">&nbsp;Channel 1</li>
    <li><input class="channels" type="checkbox" name="8" value="y">&nbsp;Channel 2</li>
    <li><input class="channels" type="checkbox" name="9" value="y">&nbsp;Channel 3</li>
    <li><input class="channels" type="checkbox" name="6" value="y">&nbsp;Channel 4</li>
    <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 5</li>
</ul>

CSS：

.channel_list{
    -webkit-column-count: 3; /* Chrome, Safari, Opera */
    -moz-column-count: 3; /* Firefox */
    column-count: 3;
}
.channel_list li{ list-style: none}

我想要的东西 -

我试试：

.channel_list li{ border-right: 5px solid red}

  

只有li右侧的边框，但不是最后的边框   列。

如果我对问题的理解是正确的，您可以使用column-rule property来实现此目的。它是一种速记属性，由column-rule-width，column-rule-color和column-rule-style组成。这三个长手属性的工作方式与border-width，border-color和border-style完全相同。 column-rule-style支持border-style支持的所有值。

请注意，您 无法生成舍入的分隔符 （也就是说，没有等效的border-radius）。

（属性still needs vendor prefixes in all browsers other than IE!。）

.channel_list {
  padding: 0;
  text-align: center; /* make the separator look like it is in middle */
  -webkit-column-count: 3;  /* Chrome, Safari, Opera */
  -moz-column-count: 3;  /* Firefox */
  column-count: 3;
  
  /* just for spacing */
  -webkit-column-gap: 20px;
  -moz-column-gap: 20px;
  column-gap: 20px;
}
.channel_list li {
  list-style: none;
}
.channel_list.solid {
  -webkit-column-rule: 5px solid red;
  -moz-column-rule: 5px solid red;
  column-rule: 5px solid red;
}
.channel_list.dashed {
  -webkit-column-rule: thin dashed chocolate;
  -moz-column-rule: thin dashed chocolate;
  column-rule: thin dashed chocolate;
}
.channel_list.dotted {
  -webkit-column-rule: medium dotted rebeccapurple;
  -moz-column-rule: thin dotted rebeccapurple;
  column-rule: thin dotted rebeccapurple;
}

<ul class="channel_list solid">
  <li>
    <input class="channels" type="checkbox" name="7" value="y">&nbsp;Channel 1</li>
  <li>
    <input class="channels" type="checkbox" name="8" value="y">&nbsp;Channel 2</li>
  <li>
    <input class="channels" type="checkbox" name="9" value="y">&nbsp;Channel 3</li>
  <li>
    <input class="channels" type="checkbox" name="6" value="y">&nbsp;Channel 4</li>
  <li>
    <input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 5</li>
</ul>
<hr>
<ul class="channel_list dashed">
  <li>
    <input class="channels" type="checkbox" name="7" value="y">&nbsp;Channel 1</li>
  <li>
    <input class="channels" type="checkbox" name="8" value="y">&nbsp;Channel 2</li>
  <li>
    <input class="channels" type="checkbox" name="9" value="y">&nbsp;Channel 3</li>
  <li>
    <input class="channels" type="checkbox" name="6" value="y">&nbsp;Channel 4</li>
  <li>
    <input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 5</li>
</ul>
<hr>
<ul class="channel_list dotted">
  <li>
    <input class="channels" type="checkbox" name="7" value="y">&nbsp;Channel 1</li>
  <li>
    <input class="channels" type="checkbox" name="8" value="y">&nbsp;Channel 2</li>
  <li>
    <input class="channels" type="checkbox" name="9" value="y">&nbsp;Channel 3</li>
  <li>
    <input class="channels" type="checkbox" name="6" value="y">&nbsp;Channel 4</li>
  <li>
    <input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 5</li>
</ul>

使用列规则

     -webkit-column-rule: 4px outset red; /* Chrome, Safari, Opera */
     -moz-column-rule: 4px outset red; /* Firefox */
     column-rule: 4px outset red;

只是另一种替代方案。

.channel_list{
    -webkit-column-count: 3; /* Chrome, Safari, Opera */
    -moz-column-count: 3; /* Firefox */
    column-count: 3;
}
.channel_list li{ list-style: none;border-right:5px solid red}
.channel_list li:nth-child(n+9){border-right:none} /* selects from the ninth onwards */

<ul class="channel_list">
    <li><input class="channels" type="checkbox" name="7" value="y">&nbsp;Channel 1</li>
    <li><input class="channels" type="checkbox" name="8" value="y">&nbsp;Channel 2</li>
    <li><input class="channels" type="checkbox" name="9" value="y">&nbsp;Channel 3</li>
    <li><input class="channels" type="checkbox" name="6" value="y">&nbsp;Channel 4</li>
    <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 5</li>
      <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 6</li>
      <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 7</li>
      <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 8</li>
      <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 9</li>
      <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 10</li>
       <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 11</li>
       <li><input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 12</li>
</ul>
