Drupal 8

In Drupal 8, we have implemented a membership-type website that will control and display views or lists of contents according to a member's membership group. The Drupal Group module seems to be the most ideal solution https://www.drupal.org/project/group.

Normally, in this scenario, one will set up the group module, content types, permissions, etc. like described below:

Views is a powerful module used in Drupal. It enables displaying content in all sorts of ways and flexible manners. Normally, you would fetch a listing or a display of contents with certain requirements, with each listed item clickable and linked to its inner page of that content. Even within the inner pages, you would normally include the same results list somewhere for easy reference, for instance as a sidebar block.

To add CAPTCHA to forms using the Webform module, for example contact forms:

Output as fields on twig

Using below references, managed to output combined custom fields - first name and last name fields in user.html.twig template, without using hook alters or overwriting the user page template file:

In Drupal, the user page is by default templated and composed depending on whatever module has been installed and enabled to show in the user page. With Drupal, there are always many flexible ways to do stuff and achieve what you need. While there was a module, Tab Tamer, for Drupal 7 specifically for customizing the tabs on the user profile page, with Drupal 8 onwards, to date, you may need to remove or hide these tabs thru any of the following:  

If you are using Drupal's core Contact module and yet the form is not showing up from the menu, check on the following:

Masonry image effect not working, images placed vertically on top of one another

• If on views, try to disable the Views Row Classes by going to disabling it under your Views display > Format > Masonry > Settings, then uncheck/unselect the "add views row classes"
• Check the required Masonry libraries are installed and placed correctly, see the project page documentation and follow the exact installation of the libraries

Masonry images overlap on responsive and mobile views

When saving a content type with paragraphs block used, produces an error - This entity (paragraph: xxx) cannot be referenced.

For Drupal 7, Views grouping and rewriting has been easy due to easy retrieval and controls of tokens. On D8, this gets tricky for the Date Views. If you have a set-up similar to this, the steps in the subsequent section might help:
