HTML <iframe> Tag
An iframe is used to embed another document into a website, this can be a youtube vide, 360 virtual tour or even another webpage.
The iframe is used in Internet Explorer, Mozilla, Opera, Chrome and Safari which means it can be used safely on your website.
The use of iframes can be done in many ways and there is no real right or wrong way to do this as the best way depends on the final output required. Also for example if you use WordPress you use plugins to enalbe short codes.
In HTML5 we have new attributes that we can use such as sandbox, seamless and srdoc which we will show you how to use later.
Basic iframe coding:-
