How to hide the title menu on the left in the learn.microsoft documentation?

Hello Giezi. At this time, the website has no functionality available to hide the provided left-side title menu in the documentation interface. The navigation pane is part of the site's responsive design, it is there to allow users easy access to all the related topis and sections that relate to each other. This works fine with wide screen devices, but may feel intrusive, especially with users who may want to have a deep reading or research experience as you pointed out.

Microsoft presently has not provided a toggle or settings for “focus mode” on documentation pages like other apps which allow this.

In the meantime, the best option is to resize the browser window or use reader mode (available on Microsoft Edge or other browser) that can minimize distractions.

Best regards,
