HTML srcdoc Attribute
Definition and Usage
The srcdoc attribute specifies the HTML content of the page to show in the
inline frame.
Tip: This attribute is expected to be used together with the sandbox
and seamless attributes.
If a browser supports the srcdoc attribute, it will override the content
specified in the src attribute (if present).
If a browser does NOT support the srcdoc attribute, it will show the file
specified in the src attribute instead (if present).
