Recipes

This chapter provides several recipes to working with the Classic UI in Plone 6.

Add custom classes to the body element

Body classes are generated in the LayoutPolicy.bodyClass method in the module plone.app.layout.globals.layout. It allows you to create your own body-classes using named adapters.

First create a class as follows.

from plone.app.layout.globals.interfaces import IBodyClassAdapter

@implementer(IBodyClassAdapter)
class CustomBodyClasses(object):
    """Additional body classes adapter."""
    def __init__(self, context, request):
        self.context = context
        self.request = request

    def get_classes(self, template, view):
        return ["additional-class", "another-css-class"]

Then register the adapter in ZCML.

<adapter
    factory=".custombodyclasses.CustomBodyClasses"
    for="* *"
    name="myproject-customclasses"
/>
