Too Long; Didn't Read
Google Chrome has a security feature that blocks a frame with origin from accessing a cross-origin frame. This can happen when you try to show material from another website on your own. The same-origin policy prevents scripts from accessing content of sites with different origins. Using a local web server or using a browser with cross-domain web security/same-origin is the best way to deal with this issue. Using extensions like “xampp’s” or “Live Server” is another way to solve it.
