On which CMS to create a site for correspondence?

Question

css

Hello to all!
There was an idea to create a website whose sole purpose would be to send a message to another person.
That is, I understand that there is vk.com, facebook and others. But in my case, complete privacy is needed. I have already raised my web server on apache and it remains to write only the site. Which CMS or builder is better to choose and where to start in general? Previously, I made sites only according to templates, that is, I didn’t write myself in PHP, CSS, HTML5
. The functionality will only consist in sending a message to a person, and if you get an attachment and sending a photo.
Thank you very much

More or less like this:

<div class="wrap">
<div class="content">
</div>
<div class="menu">
</div>
</div>

<style>
   .wrap { position: relative; overflow: hidden; }
   .menu { position: absolute; top: 0; left: 0; width: 150px; height: 100%; }
   .content { padding-left: 150px;  }
   .wrap.collapsed .menu { left: -150px; }
   .wrap.collapsed .content { padding-left: 0px; }
</style>

By clicking on something, we add / remove the .collapsed class from .wrap. Add transitions to taste :)

There is an example https://mango.github.io/slideout/ so why not use it.
And in a simple version, you make a list menu in the styles for the desktop, you specify, for example. float:left and for burger display:none, and for mobile float:none and burger display:block

Bundle WordPress + BuddyPress. For your task it will be a little cumbersome, but everything you need is out of the box. If you add bbpress, you will also get a forum. The messaging system is quite convenient. If you want to close yourself from the outside world, install the ThemeMyLogin plugin. It has the ability to block unauthorized visitors from viewing the site, set a lock if the password is entered incorrectly a certain number of times, and many other useful things.

Answer 5

Just the same, no .. all correspondence and photos should remain on my server and not on someone else
