What are store procedures? How to use it with Drupal 8?

Is there any step by step document available to improve Drupal 8 website performance?

Hi,

What are slow query logs? How do we analyse these logs to improve site performance?

I have a link that displays a modal window.

When I click on it, it is marked in the title of the modal window "Array".

How to customize the title ?

Here is my Drupal module :

/src/Plugin/Commerce/CheckoutPane/MarketplaceTermsAndConditions.php :

I created a code that displays a link to open a modal window.

The problem is that the text comes out of the window.

When I inspect the code of my page, there is an online style `style="max-height: 570px;"`

How to remove the online style of modal ?
