I'm trying to add a class to body (cms-page-aboutus) via layout XML update inside Magento 2 admin panel.
I know that CMS pages already add a body I could use to target my page, but I need to target multiple CMS pages for several languages at once (cms-about-us, cms-acerca-de, cms-a-propos).
I don't want to duplicate CSS, therefore a common class would be best.
I have tried the following:
<body>
<attribute name="class" value="body-class" />
</body>
But it fails to save in admin panel:
Please correct the XML data and try again. Element 'body': This element is not expected. Expected is one of ( referenceContainer, container, update, move ). Line: 2
Since it seems that only "update" keyword is allowed, I tried using it to add a new handle:
<update handle="cms_page_aboutus"/>
and then created the file:
app/design/<>/<>/Magento_Cms/layout/cms_page_aboutus.xml
with the body update within, but it does not work.
Any idea?
