Is it possible to make and how a narrowly targeted cms for a landing page?

Question

CMS

Good day.
Perhaps I didn't formulate the question correctly. For this I apologize.
There is a landing page for html, java, . This is a small demonstration project, which is not planned to be used for its intended purpose in the future. It is necessary to add the ability to edit text, headings and replace images. I have never dealt with such issues, and I present only very figuratively.
Is it possible somehow to implement this and how?
If there are ready-made solutions, I would be very grateful.
Thanks

Answer 1

What you can really do on your own now is the framework / cms ModX there is quite a lot of functionality and everything is very flexible, but in your case you need to analyze every moment, because I’m not sure that I could help you.

Answer 2

Any CMS will suit you. Because you need to change the texts corny, take wordpress, it is the most primitive.

Answer 3

MODX Revo is fully suitable for landing pages, and in the future, if desired, you can expand the functionality using applications.
