spaceevenly

Space evenly, or space-evenly, is a value for the justify-content property used in both CSS flexbox and CSS grid layout models. It directs the distribution of free space along the main axis so that all gaps between and around items are equal.

In a horizontal flex container, space-evenly places an equal amount of space before the first item, between each pair of adjacent items, and after the last item. The effect is a uniform rhythm of spacing across the entire line. In grid layouts, space-evenly can be applied to align and distribute content along the chosen axis, yielding the same uniform gaps between grid items and the container edges.

Compared with other space values, space-between creates equal gaps only between items with no gap at the container ends, while space-around places half-sized gaps at the ends. Space-evenly resolves these distinctions by ensuring equal gaps throughout, including at the container edges.

Usage considerations include browser support and layout goals. Space-evenly is supported in modern browsers but is not available in older browsers such as Internet Explorer 11. When compatibility is a concern, authors may provide fallbacks using alternative values or layout techniques, such as margins or gap properties, to approximate the result.

Related concepts include the CSS flexbox and grid specifications, the gap property for controlling spacing, and alternative distribution values like space-between and space-around. Space-evenly remains a convenient option for achieving uniform distribution of items in responsive layouts.
