/** |
|
* @file |
|
* Theme override for a menu block. |
|
* |
|
* Available variables: |
|
* - plugin_id: The ID of the block implementation. |
|
* - label: The configured label of the block if visible. |
|
* - configuration: A list of the block's configuration values. |
|
* - label: The configured label for the block. |
|
* - label_display: The display settings for the label. |
|
* - provider: The module or other provider that provided this block plugin. |
|
* - Block plugin specific settings will also be stored here. |
|
* - in_preview: Whether the plugin is being rendered in preview mode. |
|
* - content: The content of this block. |
|
* - attributes: HTML attributes for the containing element. |
|
* - id: A valid HTML ID and guaranteed unique. |
|
* - title_attributes: HTML attributes for the title element. |
|
* - content_attributes: HTML attributes for the content element. |
|
* - title_prefix: Additional output populated by modules, intended to be |
|
* displayed in front of the main title tag that appears in the template. |
|
* - title_suffix: Additional output populated by modules, intended to be |
|
* displayed after the main title tag that appears in the template. |
|
* |
|
* Headings should be used on navigation menus that consistently appear on |
|
* multiple pages. When this menu block's label is configured to not be |
|
* displayed, it is automatically made invisible using the 'visually-hidden' CSS |
|
* class, which still keeps it visible for screen-readers and assistive |
|
* technology. Headings allow screen-reader and keyboard only users to navigate |
|
* to or skip the links. |
|
* See http://juicystudio.com/article/screen-readers-display-none.php and |
