Change content width in sidebar mode

Dear Movin/ Support Team,

I wish to reduce the content width in right sidebar mode. I tried to do that but it breaks the layout on mobile devices. Kindly suggest the correct way of doing it and share the code if possible.

Thank you.

Hi Amit,

I hope you are well today and thank you for your question.

Could you please tell me whether you want to reduce width of content area or sidebar area so that i can help you?

Also if you reduce the width of one area then to fill that width we have to increase width of other area.

Kind Regards,
Movin
