Drupal 8.x

So I have Drupal 8 webform and it uses a multi page wizard. I've noticed that when I hit the previous button, the required fields on the CURRENT page give the JS validation errors saying that the fields are required. How can I turn off validation when the user clicks on the previous button? I am also using the new signature field and I get the same validation error on the first empty required field on the current page when click on the "Reset" button to clear the signature. It seems that any button that is pressed triggers the form validation.

Hello, new to drupal and couldn't see a similar case. I tried all the other solutions that solved '403 forbidden' error but couldn't lad a solution.

I would like to add classes directly to the a element for the "Add child page" and "Printer-friendly version" links in the Book module that comes with Drupal 8.

Hey guys,

We recently created a bare dockerized Drupal 8 starting point that isn't bloated with a bunch of extra modules and scripts for our projects and thought it may be useful to others. Happy to hear feedback or requests that are within scope (scope being the top devops layer only - not theme related) that aren't already included.

Basic overview:

How can I get the current region ID inside hook_preprocess_block()?
I tried the following code, but it seems something is wrong.

function ThemeName_preprocess_block(&$variables) {
  if ($variables['elements']['#region'] == "nav") {
    $variables['attributes']['class'][] = 'SomeStyle';
  }
}

I have created block file at "src/Plugin/Block/ArticleBlock.php"
Given the class name as "ArticleBlock"
Created info.yml for modules and enabled modules
Cleared cache more than 1000 times
Checked by clicking "place block" on structure/block layout

My block is not there.

Did i missed something?? anybody had already faced this issue.
