Using a Separator in a Column

Question

I want to use a separator in each column when using CSS column-column .

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}

What I want,

I'm trying to:

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

Only the border is on the right side, but not in the last column.

Answer 1

If my understanding of the question is correct, you can achieve this using the property column-rule. This is a shorthand property consisting of column-rule-width, column-rule-colorand column-rule-style. These three long properties work just like border-width, border-colorand border-style. column-rule-stylesupports all values ​​supported border-style.

, (.. border-radius).

( - , 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>

    <input class="channels" type="checkbox" name="5" value="y">&nbsp;Channel 5</li>

Just another alternative solution.

.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>
