I recommended using Publii (https://getpublii.com).

All available themes you can find at marketplace.getpublii.com To install the new one just drag and drop the theme zip file onto the Available themes section; https://getpublii.com/docs/installing-and-updating-publii-th...

You can backup your website via Tools Backup or you can deploy it to .zip or .tar file via Server option.

You can use Dropbox or other cloud storage service https://getpublii.com/docs/publii-on-multiple-computers-via-...

Download Windows or MacOS Installer (https://getpublii.com/) and install it on your mother's computer. No tech knowledge is required to manage a website with Publi.

Hi Stephner, in part, you're right; but Publii allows you to share the website files via e.g. Dropbox and manage your site by multiple authors. https://getpublii.com/docs/publii-on-multiple-computers-via-...

So does literally any other file editor.

What is gained from being this reductive?

Tomte, you can download the installer for Windows or macOs from the app homepage: https://getpublii.com/
