I have the below XML which adds my static block to the page sidebar, then removes the wishlist. I would like to add a div wrapper to this static block with a css class.
I thought this could be done with the following argument, but it does not work.
<argument name="css_class" xsi:type="string">faq</argument>
Here is the full XML so far if anyone could help it would be appreciated.
<referenceContainer name="sidebar.additional">
<block class="Magento\Cms\Block\Block" name="faq_sidebar">
<arguments>
<argument name="block_id" xsi:type="string">faq_sidebar</argument>
<argument name="css_class" xsi:type="string">faq</argument>
</arguments>
</block>
</referenceContainer>
