CSS - columns

Example

.content-box {
  border: 10px solid #000000;
  columns:3;
}

Syntax  

columns: 1em;
columns: 1;
columns: auto;
columns: 1 auto;
columns: auto 12em;
columns: auto auto;

Values

<'column-width'>

Is a <length> value giving a hint of the optimal width of the column. The actual column width may be wider (to fill the available space), or narrower (only if the available space is smaller than the specified column width). The length must be strictly positive or the declaration is invalid.

<'column-count'>

Is a strictly positive <integer> describing the ideal number of columns into which the content of the element will be flowed. If the column-width is also set to a non-auto value, it merely indicates the maximum allowed number of columns.

Formal syntax

<a href="css/column-width" title="&lt;length&gt; | auto"><'column-width'></a> <a href="css/value_definition_syntax#double_bar" title="Double bar">||</a> <a href="css/column-count" title="&lt;number&gt; | auto"><'column-count'></a>

Description  

The columns CSS property is a shorthand property allowing to set both the column-width and the column-count properties at the same time.
