javascript inserting code into website

Site URL: https://www.rentat45.com

I have been supplied code from a vendor that needs to be added to my website. I have successfully added iframes but this is beyond my skills/abilities. Can someone help or guide me in the right direction?

This is the information I was sent:

 
Tour URL - https://viewer.panoskin.com?tour=61f7f7cf7721160624bd5910
 
Embed Info
 
1. Create the following container within your webpage
            <style>
                #tour {
                  width: 100%;
                  height: 100%;
                  min-height: 562px;
                  margin: 0 auto;
                }
            </style>
            <div id="tour"></div>
           
2. Add the following JavaScript snippet before the end of your closing body tag </body>
            <script src="//lcp360.cachefly.net/panoskin.min.js"></script>
            <script>
                PANOSKIN.createViewer({
                  id: 'tour',
                  tour: '61f7f7cf7721160624bd5910'
                });
            </script>
