Theme development

I have a "Our Staff" Content Type, that includes a field for uploading an individual's CV as a PDF:

The machine Name is:

field_cv_file

I have created a View for this Content Type, which I have then added to the page via Blocks
I have a twig file that I'm using to style the Staff area:

views-view-fields--our-staff-view--block-1.html

I can render all other fields,
but I'm having trouble with the URL for the File Field

How to display since when the node was created with TWIG. Here is the templace of my node :

Hello,

  Can someone please advise how I can add something like this https://codepen.io/shvvffle/pen/JRALqG to a block on my site? Or even point me toward to a module that does the same thing. Thank you.

What I did was create a counter,js file and paste the javascript code in there and upload to the /site/all/theme_name/js directory and specify it in the theme_name.info file. Also copied the css file in to the css directory of the theme and also specified in the theme_name.info file as well.  

I've got a completely built site under Symfony 4.3 with a working theme split into multiple twig templates (ex., header/body/footer/etc).  How difficult would it be to refactor those twig templates into Druapl?

i need a hand about this particular (tricky) subject about Drupal 8. How to alter form in such way to remove those annoying fieldsets wrapping everything: radios buttons, checkboxes, addressField .. ? if possible globally, not necessarily addressing a particular fieldset in particular form.

Drupal 8, by its default internal process of rendering Forms, use (unnecessary) many nested containers to wrap and structure from elements which absolutely makes the html output little bit complicated when it comes to work with css frameworks (Bootstrap 4 in my case)

Hello,

I am trying to write a twig file to print menu (main--menu.html.twig). My menu and sub-menu links are showing, but I need to get the name of the menu item after I get into

{% macro submenu_links(items, attributes, menu_level) %}
  {% import _self as menus %}

Say I have Menu structure like 

-Cars

-- BMW

-- Toyota

- Bikes

-- Harley

-- Yamaha
