This is an article I have seen from other blogs, some of which are my own summaries, so I still want to locate the original and hope to provide more help to you.
Recently, I started to involve website knowledge and had to have a deeper understanding of html tags. I just saw a website that uses object tags to achieve some amazing results, so I searched for the relevant object content and wrote this blog post based on my own experiences.
HTML <object> tag
Definition and usage
Defines an embedded object. Use this element to add multimedia to your XHTML page. This element allows you to specify the data and parameters of objects inserted into the HTML document, as well as code that can be used to display and manipulate data.
<Object> tags are used to include objects, such as images, audios, videos, Java applets, ActiveX, PDF, and Flash.
The original intention of the object is to replace the img and applet elements. However, this is not implemented due to vulnerabilities and lack of browser support.
The support for browser objects depends on the object type. Unfortunately, mainstream browsers use different codes to load the same object type.
Fortunately, the object provides 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 ).
Instance
Add an object to HTML code:
Object tags can be used to implement flash animation with images.
<Object> attributes of a tag can be defined as long and wide as needed. Other values do not need to be added.
<Param value = "Path of the animation or image to be displayed"> </param>
<Param name = "vmode" value = "transparent"> </param> defines the transparency of two attributes.
</Object>
Browser support
Almost all mainstream browsers partially support <object> tags.
Differences between HTML and XHTML
NONE
Tips and notes:
Note: The <param> label defines the run-time settings of the object.
Note: Do not use the <object> label for the image. Use the label instead.
