Div 's without class appearing into my html file

Hi there,

I am trying to create a website with pydash in order to present some data visualization.

I followed exactly the tutorial about creating multiple pages with callbacks.

I create my app.layout with my html.div 's giving class and id to everything, although the html that coming out when I execute the localhost contains a couple of div’s with classes as “dash - debug - menu” & “dash-app-content” but on the top of that creates 3 div’s without class which I do not know from where they are coming.

This is really annoying as i try to style it and this div’s prevent me from that :slight_smile:

Please check the screenshot from the html file: https://prnt.sc/pp7y3l

Thank you in advance!
