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"
/>
