Hey there,

I used 'C-h r' and found the man page for this under '13.9.12 CSS support' for the Org Mode manual.

Here's the section:
*   In order to add styles to a sub-tree, use the ‘HTML_CONTAINER_CLASS’**
*
*property to assign a class to the tree.  In order to specify CSS styles**
*
*for a particular headline, you can use the ID specified in a ‘CUSTOM_ID’**
*
*property.  You can also assign a specific class to a headline with the**
*
*‘HTML_HEADLINE_CLASS’ property.*

Thanks for providing this, as I had no idea you can do this, great to know!

Will use this to create some 'flexbox' elements using containers with this in mind :)

Thanks again,

Sam
