HTML5 series of NOP tags

Old Tags:

(1) <noscript> label

Role: A browser used to define alternative content (text) that can be used to identify <noscript> tag but cannot support scripts when the script is not executed

(2) <object> label

Role: Define an embedded object, use this element to add multimedia to your XHTML page. This element allows you to specify the data and parameters for inserting objects in an HTML document, as well as code that can be used to display and manipulate the data.

<object> tags are used to include objects, images, audio, video, Java applets, ActiveX, PDF, and Flash.

Object support for the browser depends on the object type. Unfortunately, mainstream browsers use different code to load the same object type.

Fortunately, object objects provide a solution. If the object element is not displayed, the code between <object> and </object> is executed. In this way, we can nest multiple object elements (each corresponding to a browser).
