There are a few ways by which sites connect with each other. Two common ways are linking and framing. Linking is a commonly known process among users, it is also known as hyper linking.
In this section we will talk about how users can embed content (videos, web pages etc) into the lesson pages on Teamie.
Besides using external links, another way to connect from one site to other sites is “framing.” Framing is similar to linking in a way that you code a word or image so that it will connect to another web page when the user clicks on it. What makes framing different is that instead of taking the user to the linked site, the information from that site is imported into the original page and displayed in a special 'frame'. But sometime embedding code URL becomes problematic if content does not appear in lesson after rendering and iFrame simply shows the blank page. The potential reasons behind this are listed below:
1. Other sites can decide whether or not a browser should be allowed to render a page in an iframe. Sites can use restrictions to ensure that their content is not embedded into other sites.
2. If you have insecure (HTTP) content being loaded into a secure (HTTPS) page or frame, it may get blocked. So if any embedded code URL does not work, check whether it has "http or https", if it has http, try replacing it with https. This might resolve the issue.
