Reenabled Caption on Main-Article-ImageReenabled Caption on Main-Article-Image
In the Drupal 7 version the caption of the main article images was handelt by two bits:
- The function hook_preprocess_image() in the theme to add the class "caption" to the image tag
- The module image_caption which added a jQuery-Function to do the work
The module doesn't exist for Drupal 8. The preprocess_image hook luckily still is available.
- With adding the function in the .theme-file of our theme, it was feasable to add the class "caption" to an image set by an image-field when the images style is w225xh150.
- The jQuery-Function was put into the themes js directory into the file "drupal8_w3css_subtheme.theme". There the function worked as in the Drupal 7 version.
Caution: when in Drupal 10 jQuery is eliminated, the script has to be rewritten.
