I recently used Drupal's Feature Toggle module<\/a> to set a data attribute which enabled some new styling for buttons.<\/p>\n\n

Firstly, within the theme's .theme file, I added this code:<\/p>\n\n

\/**\n * Implements hook_preprocess_html().\n *\/\nfunction mytheme_preprocess_html(array &$variables): void {\n  $variables['attributes']['data-use-new-button-styles'] = \\Drupal::service('feature_toggle.feature_status')->getStatus('use_the_new_button_styling');\n}\n<\/code><\/pre>\n\n

If the feature toggle is enabled, it adds a data-use-new-button-styles=\"\"<\/code> attribute to the body<\/code> element.<\/p>\n\n

If it is disabled, the attribute is not added, so I can write CSS that's applied when the data attribute is present:<\/p>\n\n

[data-use-new-button-styles] .btn-primary {\n  background-color: red;\n}\n<\/code><\/pre>\n\n

In a Tailwind CSS project (this isn't), the same could be achiveable with a custom interaction state - similar to hover<\/code>, focus<\/code> and active<\/code>. Something like new-button-styles:bg-red-500<\/code>.<\/p>\n\n

I like using feature flags and was happy to find a way to use them when adding this new CSS.<\/p>\n\n ", "format": "full_html", "processed": "\n
