Hi,
Due to the unique layout of this theme, It’s not possible to reduce sidebar and widen content with a few custom css codes. It requires modification to desktop and mobile layout as well as javascript that controls the sidebar toggles.
Many people has tried and failed.

I do not have the knowledge to assist in completing this customization.
You can put up a feature request on Hueman theme’s github, for an option to adjust sidebar width and content width.

The Theme Author will make the decision whether to provide this feature.
Thank you
