Drupal 8.x

At first I had problems to start with single non-Drupal -PHP-file, but found the solution.

Now I try to build more complicated application of some connected php-files. My PHP/MySQL-solution works fine in XAMPP and (free) hosting service. Both are witout Drupal. Now I use this php-application with another (paid) hosting service with drupal installation.

I have done several websites with Drupal 7, so I am not a complete newbie.

Now as I am trying my luck with Drupal 8, for the first time ever, I made a very simple test module in Drupal 7 style, and tried to install it by following my trusted personal installation log, by which commands and actions I have successfully installed my Drupal 7 modules.

I'm looking to display number values as such below - 

And so on. I've found a module that does this but only for 7.x and is no longer maintained. I've looked extensively to find an alternative but have had no such luck. Is there possibly another way to accomplish this?

i am a web designer working with many clients one of my client ask for a pop-up form on his domain, i don't know how to create a lead generation pop-up form in drupal. i tried many plugins but not able to do like he want. he also send me a refrence domain like he want : the domain is : https://www.southafricapackages.com/  on this domain a pop-up form appears as it load with a closing button. help me for this issue if any option available to do this kindly reply to this post. Thanks.

I know (generally) what I want as my end result, but I'm completely lost in how to even approach this problem. I have a custom module that interacts with Webform in various ways, to include dynamically creating select values and text based on results in a database. The element itself is a "Custom Composite" element, with the select as one portion and users can add as many rows as required. I need to generate a hyperlink or button that will take the user (via a new tab) to a page that provides details about the selected Ticket ID (the url will be of the form: ~/page/{select_value}).

Hi I am trying drupal for the first time.

I checked log and found nothing. Server support says all is well.

Is the above in for sufficient for help?
