Available since SPIP 4.0, the |supprimer_class filter removes a class or multiple classes from an HTML tag.
Example
#LOGO_RUBRIQUE
Generates the following HTML:
<img
	src="IMG/logo/essai-1.jpg?1614197741"
	class="spip_logo"
	width="800"
	height="600"
	alt=""/>
If we apply the |supprimer_class filter
[(#LOGO_RUBRIQUE|supprimer_class{spip_logo})]
The result is:
<img
	src="IMG/logo/essai-1.jpg?1614197741"
	width="800"
	height="600"
	alt=""/>
