How to add iFrame. Plugin or Code?
I want to add an iFrame on all external links. Means if anyone click on my coupon code or promotion button, they should redirect to some other page of mine and the external website should open in iFrame with keeping my header.
Please check this website.
(If you click on any post, it redirects to some url like parent website/posts/code)
This kind of pages open http://roofinfo.com/posts/stewardshi...ing-green-2068
In this page you can find that parent website header is there and its also good to reduce bounce rate.
Please tell me how to implement this as I am new in coding.
