Paragraphs is the new way of content creation!
It allows you — Site Builders — to make things cleaner so that you can give more editing power to your end-users. Instead of putting all their content in one WYSIWYG body field including images and videos, end-users can now choose on-the-fly between pre-defined Paragraph Types independent from one another. Paragraph Types can be anything you want from a simple text block or image to a complex and configurable slideshow.
This demo creates some default Paragraph types from which you can easily create some content (Nested Paragraph, Text, Image + Text, Text + Image, Image and User). It also includes some basic styling and assures that the content is responsive on any device.
Apart from the included Paragraph types, you can create your own simply by going to Structure -> Paragraphs types.
