Drupal 8.x

Hello, I wanted to know if there is a way to override the default search form block and remove the search box, leaving the search button only. Should I use the hook_form_alter  in the .theme file or should I change the block---search-form-block.html.twig file? And I also wanted to know how to add Font Awesome's search icon on the button.

Thank you for your replies in advance, and any solutions would be most welcome. I am still new to Drupal and I would be really grateful for any help that you provide me with.

Hello,
I am trying to upgrade to the latest version (Sept. 24) of animate_css by running "composer require 'drupal/animate_css:^1.1'". I am on Drupal 8.7.7. However, I get the error messages below:

Did you accidentally name your root package after an external package?

The composer.json file of animate_css contains the following lines:

Hi,

I have joined two tables in hook_views_query_alter(). But if I want to display the information stored in one of the columns of the joined tables, on making a GET request, what should I do?

Thanks,
