Felipe, no way, you can use a "Ferrari" to solve a simple problem, that would be Wordpress in the similar molds that the brasofilo answered, or you create a very simple own resource, which is the purpose of this my answer.
So I leave here for you to choose the best way. Seeing the comments if you want to use JS, in any case a PHP to persist the data in the database, via AJAX (there are other features for BD recording, but it is not ideal in this case).
I want to give this option to you in two steps:
1. A Jquery plugin for you to be able to edit inline text, that is, on the same screen as you are viewed content:
2. It’s no use the above feature if anyone can edit, so I recommend reading below to create a very simple PHP authentication system. In your case, after authenticated, return to the normal site screen, but enabling the editing events through the above plugin. Follow the tutorial:
3. PHP files that "will receive AJAX". Respecting and understanding items 1 and 2 you will be able to do this step without problem.
I hope I gave you a valid option for your project.
Hugs.
The texts/sections would be fixed for example, header, menu text, main div text, footer?

That’s right, there is a part of the site that has a text and an image, and the client wants to leave manageable. ONLY this part, the rest is all fixed same.

If you only work with HTML and don’t want to work with the server-side (PHP, Node.js, etc.) I’m sorry but this is impossible unless your client knows html and FTP.

He does not know. Has how to do this via Wordpress?
– Felipe Viero Goulart
@Felipestoker does, but you have to know a little PHP and a database access to save the paragraph. I don’t handle WP so I don’t know very well the structure unfortunately. but I think a simple answer explaining step by step can arise. Do you have access to the hosting account? will be necessary for the database..
– Olimon F.
I have access to FTP yes, I have Wordpress and BD installed and configuring pulling the data, just do not know how to do this =/
– Felipe Viero Goulart
You can post as answer yes. Anything, I ask there
– Felipe Viero Goulart
Maybe you could create a TXT on the server containing the text that will be in this paragraph then add an insert via PHP

Felipe, please prefer [Dit] the question to add details. We should not need to read the comments to understand the situation.
