Introduction
Since I first started using Backdrop CMS, I have been contributing to both the Backdrop CMS core product and the large number of add-on modules and themes.
While many modules listed here are modules I ported (and in most cases improved), I created three (Layout Custom Theme, Admin Bar This Page Content Type, Paragraphs jQuery UI Accordion2) for Backdrop CMS and also some modules I joined as a co-maintainer to help fix bugs and add features or took over being the maintainer where the original maintainer was unable to continue.

Sometimes you might have a page with a lot of content that the reader may not need to access all of. A common example is a frequently asked questions page or installation instructions that might have different parts for different systems. An accordion structure can reduce the amount...
Paragraphs is one of the most powerful modules that Backdrop CMS has for presenting content in the way you need. Different paragraph types can have different field types and different arrangements allowing...
If you want to enter your content using Parsedown, then this provides an input filter to do so. It also includes Markdown Extra.
Sometimes you don't want to fully take the site offline but you do want to stop content being added, changed or deleted or configuration being changed; this module allows that. You can configure forms that are allowed (perhaps the form goes to an external service or just to email without being...
If your site is a church website, a Christian ministry of some sort, or a blog that covers Christian matters you may well want to refer to Bible verses in your text. This module will convert standard bible references (e.g. John 3:16) into links to a small popup window with the text of short...
