I don't think these have any purpose. @paulbalandan do you know?

[paulbalandan]

The raw:: html actually embeds the following HTML into the generated HTML file instead of displaying it. I'm not sure if the div classes are actually used or defined in the user guide's CSS.

@totoprayogo1916 can you show a before and after render of the user guide from this PR?

@paulbalandan : its found at contributing/documentation

but when render is not effect ,
after render, it just create empty div tag like:

@totoprayogo1916 yes it will just be put there. Can you show me what the page looks like with this div and after removing it. I am thinking maybe this div is controlling the clear: both css property. But if there's no noticeable change, I am fine removing those blocks.
