Integrates with the Akismet content moderation service.

Installation

Ever wanted to use CSS Grid because you can, but don't want to mess up older browsers? Have no fear, this module adds a little CSS to make all multicolumn layouts from Backdrop core use CSS Grid.

This module provides a customisable 'maintenance mode' page, without the need
for theming.

It allows you to customise:

PDF to Image create images from PDF files automatically. This is useful if you'd
like to display a preview of the first page of your uploaded PDF, or showcase a
gallery of all the pages in a PDF file.

PDF.js project enables you to display PDF files in a web reader, using
Mozilla's PDF.js library.

See an example.

Extended functionalities

The Node Reference URL Widget module adds a new widget to the Node Reference
field type. It auto-populates a node reference field with a value from the
URL, and does not allow this value to be changed once set.

This simple utility provides a quick way for admin to review
the number of revisions stored in the system for individual
nodes and to delete some or all of them.

iframe filter embeds content in an iframe, which is useful for embedded
external content or widgets and speeding up ad provider load times.

This module provides a drop-down breadcrumb block, and a drop-down page title
block. Each use the active menu trail to build the drop-down menus.

Menu Trail by Path allows you to set the active-trail on menu items according to
the current URL. You can also optionally set the breadcrumb trail to the same.

Defines a field type Block reference which creates a relationship to a block
and allows the block to be displayed as the content of the field.
