CSS column-fill

The CSS column-fill property allows you to balance content equally between columns on a multi-column layout.

Syntax

Possible Values

auto: Specifies that columns should be filled sequentially.
balance: Determines that content should be balanced between the columns, if possible.
balance-all: Determines that content should be balanced between the columns, if possible, including in fragmented contexts (like paged media).

In addition, all CSS properties also accept the following CSS-wide keyword values as the sole component of their property value:

initial: Represents the value specified as the property's initial value.
inherit: Represents the computed value of the property on the element's parent.
unset: This value acts as either inherit or initial, depending on whether the property is inherited or not. In other words, it sets all properties to their parent value if they are inheritable or to their initial value if not inheritable.

Media

The W3C specification states the following regarding the column-fill property:

In continuous media, this property will only be consulted if the length of columns has been constrained. Otherwise, columns will automatically be balanced.

In continous media, this property does not have any effect in overflow columns.

In paged media, this property will only have effect on the last page the multicol element appears on.

This example uses vendor prefixes for the multi-column layout due to lack of browser support for the official standard at the time of writing.

CSS Specifications

The column-fill property is defined in CSS Multi-column Layout Module Level 1 (W3C Working Draft).

Browser Support

Browser support for CSS properties can vary, particularly for newer or experimental features. Check current browser compatibility before using a property in production, especially when supporting older browsers.

The following table provided by Caniuse.com shows the level of browser support for this feature.

Initial Value

CSS properties have an initial value that applies when the property has not been explicitly set. The initial value is different from the value inherited from a parent element and may vary between properties.

Inheritance

Some CSS properties inherit their computed value from their parent element by default, while others do not. The inherit, initial, unset, and revert keywords can also be used to control how a property gets its value.

Vendor Prefixes

Most modern CSS properties use the standard, unprefixed syntax. Vendor-prefixed properties such as -webkit- are mainly relevant to older browser versions or specific features and should only be used when required by your browser support targets.
