Hi Craig,
so the easiest way to display other content form another site is to use a iFrame.
This would be the HTML for your iframe, link included:
<div class='embed-container'><iframe src='https://v360.in/viewer4.0/vision360.html?d=VETRING1&surl=https://s4.v360.in/images/company/289/' style='border:0'></iframe></div>
The we can add some CSS to style it – you can add this to the Customiser > Additional CSS or your Child Theme Style sheet if you have one:
.embed-container {
position: relative;
padding-bottom: 56.25%;
height: 0;
overflow: hidden;
max-width: 100%;
}
.embed-container iframe, .embed-container object, .embed-container embed {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
You could just add the HTML to your product description and see if it works 🙂
If you want it in a pop up or in a modal window the next step would be to get a plugin that allows you to add an iframe and create a button shortcode that you add to the description.
