Mozilla Does Not Recommend <multicol>

[ilzolende]

They really, really, really don't.

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The HTML Multi-Column Layout element (<multicol>) was an experimental element designed to allow multi-column layouts and must not be used. It never got any significant traction and is not implemented in any major browsers. It's covered here only to warn you off in case you stumble on it in any other documentation.

Do not use this! In order to implement a multi-column layout, you should be using the regular HTML elements, like <div> in conjunction with CSS columns.
