How to override the xblock loaded in a iframe in learning page

i want to override a css class inside the xblock loaded in iframe on learning page.
I tried the mfe edx-brand the brand css were not getting applied in the iframe dom element why so.
Also tried the custom indigo targed the element and added the css in the
”custom_tutorindigo\templates\customindigo\lms\static\sass\partials\lms\theme_extras.scss”
still this was also not loaded.

i have updated the indigo folders to customindigo so replaced all the templates and css location in entry point and plugin file still this css were not loaded and the brand css was not getting applied then after build the mfe and openedx again still the extra css not getting applied.

Any option how to override that css.

ex→ hide a hd-3 class element in all the xblocks on learning page.

Hi @viral - when you make a post could you please always include what version of Tutor you’re running? Thank you!

I am using the openedx teak version and the tutor 20 version.

I’m not sure how Indigo interacts with this. @tutor-maintainers any help? (as a sidebar, could I create an indigo-maintainers group to better tag the right people for Indigo questions? Who would belong to that?)
