The Safari web browser from Apple doesn't by default provide a menu option that will allow you to view the underlying HTML code on a web page. But the browser does provide that capability, you merely need to enable the "Show Develop menu in menu bar" option.
Safari does provide a capability to change the user agent string it sends to websites, which sites use to identify the browser a visitor is using. Some sites may even limit access to material on the site to specific browsers. By changing the user agent the browser reports, you may be able to still view the content in such cases.
