HtmlPruner::removeRedundantClasses( string[] $classesToKeep = array() )

Contents

Description Description

Note that this does not inspect the CSS, but expects to be provided with a list of classes that are still in use.

This method also has the (presumably beneficial) side-effect of minifying (removing superfluous whitespace from) class attributes.

Parameters Parameters

$classesToKeep

(Optional) names of classes that should not be removed

Default value: array()
