This is the second category under which Drupal offers exclusive modules to its users which enable them to design and create functional sites without the need of manual code editing.

The paragraphs which are already configured, to provide you tabs on desktop and an accordion on mobile are added by this module. There is no need to configure anything from your end. The three new paragraphs created by this module consist of:

Decorative Image Widget
The Decorative Image Widget proves to be a solution for the site builders that prefers the option of leaving an image’s alternative text blank explicit (by checking a new “Decorative” checkbox) instead of implicit (by simply leaving the alt text field blank). To put it simply, the editors are made to affirm the reason behind leaving alt text empty, which is because of the decorative image that needs to be hidden from the screen readers. The primary features of this module consist of:
- Providing an option of a “Decorative” checkbox to image widgets that has to be checked if the user chooses to leave the alt text empty.
- Forcing users to focus upon alternative text instead of leaving it blank.
- Working with any existing image widget which extends from core’s default. For example, it can be used with the default image widget or the one offered by Image Widget Crop.
- Lastly, there is no need for any kind of data model changes, since the position of the state of the “Decorative” checkbox is completely inferred from the value of the alt text.
