Making a CMS

Question

what should I consider while designing a custom cms like the database design and so

Answer 1

Basically you have to focus on the CRUD (Create Read Update Delete)
There should be a dashboard for admins and members.

It should be fairly secure. For instance I should not be able to login to the dashboard without a username and password and the username and password fields should parse the informations in the input so I cannot use PHP or MySqli commands to get into the database or dashboard.

A good CMS has to be somewhat customizable. For instance the admin or a member can change the overall color of the website.
