function template_preprocess_block

Prepares variables for block templates.

Default template: block.html.twig.

Prepares the values passed to the theme_block function to be passed into a pluggable template engine. Uses block properties to generate a series of template file suggestions. If none are found, the default block.html.twig is used.

Most themes use their own copy of block.html.twig. The default is located inside "core/modules/block/templates/block.html.twig". Look in there for the full list of available variables.

Parameters

array $variables: An associative array containing:

• elements: An associative array containing the properties of the element. Properties used: #block, #configuration, #children, #plugin_id.
