Embeds are a concept within WordPress that lets you … well … embed content by pasting a URL on it’s own line.
In addition to all the defaults in WordPress (YouTube, Twitter, etc), the following sites have support added:
- IndieGoGo
- Gleam
Examples:
https://www.indiegogo.com/projects/riley-parra-season-2-lgbt
or
https://gleam.io/iR0GQ/gleam-demo-competition
Yep, just paste that on a line all it’s own and WordPress handles the rest.
