The column-gap property

The column-gap property specifies a gap between columns in a multi-column text, as well as a gap between columns in a grid. The property value is any size units or the normal keyword (by default), at which the browser itself selects the optimal distance between columns.

Syntax

cssselector {
  column-gap: value;
}

Example

In this example the columns number column-count (3 items) and the gap between them column-gap of 50px are given. And columns width will be automatically selected to satisfy these conditions (the number of columns and the gap between them):

html<div id="elem">
  some long text
</div>

css#elem {
  column-count: 3;
  column-gap: 50px;
  text-align: justify;
}

Результат:

Example . The normal value

In this example, the column-width is 150px, their number column-count is in the auto value, and the column-gap in the normal value. Thus, the browser itself will select the required number of columns and the space between them (but their width will be 150px):

html<div id="elem">
  some long text
</div>

css#elem {
  column-gap: normal;
  column-count: auto;
  column-width: 150px;
  text-align: justify;
}

Example

Let's set the gap between columns in a grid:

html<div id="parent">
  <div id="elem1">1</div>
  <div id="elem2">2</div>
  <div id="elem3">3</div>
</div>

css#parent {
  display: grid;
  column-gap: 10px;
  padding: 10px;
  border: 2px solid #696989;
}
#parent > div {
  padding: 10px;
  border: 1px solid #696989;
}
#elem1 {
  grid-column: 1 / 2;
}
#elem2 {
  grid-column: 2 / 3;
}
#elem3 {
  grid-column: 3 / 4;
}

Результат:

Example

Now let's set the gap between columns in %:

html<div id="parent">
  <div id="elem1">1</div>
  <div id="elem2">2</div>
  <div id="elem3">3</div>
</div>

css#parent {
  display: grid;
  column-gap: 5%;
  padding: 10px;
  border: 2px solid #696989;
}
#parent > div {
  padding: 10px;
  border: 1px solid #696989;
}
#elem1 {
  grid-column: 1 / 2;
}
#elem2 {
  grid-column: 2 / 3;
}
#elem3 {
  grid-column: 3 / 4;
}
