Magento 2 : How to add inline CSS from admin Layout Update XML?

Question

In Magento 1 we can add inline CSS from admin Layout Update XML like this :

<reference name="head">
 <block type="core/text" name="custom_css">
  <action method="setText">
      <text><![CDATA[
         <style  type="text/css">
            .my-class  {
                color: red;
            }
         </style> ]]>
    </text>
  </action>
 </block>
</reference>

how can this be implemented in Magento 2 admin Layout Update XML?

I've tried it in Magento 2.2 but it did not work

Answer 1

This is not currently possible in Magento 2. You can add in CSS classes with XML (the example that @Christoph Farnleitner), but not actual CSS itself.

Answer 2

A little bit tricky, in the inside content field you can use like this :

<style xml="space"><!--
/* your css snippet here */
--></style>
