Drupal 8.x

I am working with Bootstrap Barrio Subtheme 8.x-4.22 the one issue I can't figure out is how to change the background color of text fields in contact form and in search box from white to something darker. There does not appear to be a style sheet of perhaps I am looking in the wrong place. Anny assistance is quite appreciated.

Thanks

Hi, How can I disable the submission "Edit" Buttom (under Operations [Edit, View,Duplicate,Resend,Delete])  for specific user Role. The user can't duplicate the submission , but he still can "Edit". I want when the user click on the "Edit" Button , a message shown like (You are not authorized to access this page.) like in the "Duplicate phase".   
and if can i do that programmatically ?

I am trying to replace the favicon on our site but I cannot do it through the Drupal 8 interface. I cannot find it in the folder structure. I tried uploading a new one but there was no change. Any idea on where it would be on the server? I thought it would be a simple "replace".

Hi,

Does anyone have a solution to prevent update of an entity reference view field item on a node display page when the node is in an unpublished state? 

For example, I have a content type "Daily Task List" which has an entity reference view field that lists tasks (nodes that have been created from a Task content type).  If a Task node is edited (say, to change the task interval from weekly to monthly), the Daily Task List node display field item will update to reflect the edit, irregardless of the Daily Task List node published state. 

Hello,

I am new to drupal. I am trying to migrate a drupal 7 site to drupal 8. Followed the steps as stated on official drupal migration site using drush (https://www.drupal.org/docs/8/upgrade/upgrade-using-drush#s-basic-example). 

Here is my environment:

Drupal : 8.7.10

PHP: 7.3.11

Databse(MySQL): 8.0.18

My Drupal 7 database is on a remote server (not on same server as drupal 8). Here is my database config on setting.php.
