Blogger Add Show Hide FAQ Style Toggle Contents

To have a Frequently Asked Question FAQ page at your blog can be useful for you (& your blog),  when dealing with repeatative queries asked by your blog readers. Some call FAQ pages as a Question & Answer page, where blog owners can easily point users to this page if similar questions asked online. To create one on a Blogger blog post can be challenging, the Blogger blog post editor does not have a built in show & hide feature or auto create markups to toggle expand or collapse contents. By using this technique, you do not rely on 3rd party apps or services to create one. You only add, edit, style your contents anytime, just by editing the Posts/Pages where you've published them -- using the existing blog editor tool!
