Drupal 8.x

My requirement is to create a Paragraph type Paragraph module (https://prnt.sc/voys9a) with some fields textbox and text area. I am thinking to create a simple module which create my paragraph type which i can use every where where my module available. so please guide me how can i create Paragraph type via programming.

I referenced this page https://www.drupal.org/docs/distributions/open-social/installing-open-so... when installing open social distribution.

I performed these steps

1. forked open social source

2. Cloned my repo to my local machine

3. Downloaded and downgraded Composer to 1.9.0 due to lock compatibility issues

I installed the Message module on my site. I want to set up ads for certain roles. I want to create messages and select the roles that can see the message.

How to limit messages to a role? I don't want to limit the type of message, I want to limit only the message.

Hello,

"

1. Download the module.
2. To be able to use County and jQuery Countdown plugins download them to libraries/county and libraries/jquery.countdown. This module supports jQuery Countdown 2.1.0.
3. Enable the module using admin module page or drush."

I followed the steps for D8. Downloaded the libraries as well. Enabled the module (extends > module > enable) Did not use drush. 

I have a button on my site, when I click on it, the background should be darkened.

Hi,

I'm very new to custom modules and was wondering if it's possible to create a module that basically runs a quick script.

Basically - I want to check if the URL the user is on contains certain things and if so, check for a token (or cookie or something), and if that exists grant access to the page. But if the token doesn't exist send them to a login page where they simply enter a password, and if the password is correct, add the token and grant them access.
