For MIME types, please refer to IANA MIME typesFor example: 2. Introduction to IANA MIME The multi-purpose Internet mail extension type is a type that sets a file with a certain extension to be opened by an application. When the file with the extension is accessed, the browser will automatically use the specified application to open it. Open. It is mostly used to specify some client-defined file names and some media file opening methods. Each MIME type consists of two parts. The first part is the big category of data, such as sound audio, image, etc., and the second part defines the specific type.

Introduction to HTML5 Html5 will become the new standard for HTML, XHTML and HTML DOM. The last version of HTML was created in 1999. The world of the Web has changed dramatically since then. HTML5 is still a work in progress. However, most modern browsers already have some HTML5 support. HTML5 is the result of a collaboration between the W3C and the WHATWG. ——W3C refers to World Wide Web Consortium, World Wide Web Consortium. ——WHATWG refers to Web Hypertext Application Technology Working Group. The WHATWG works on web forms and applications, while the W3C focuses on XHTML 2.0. In 2006, the two parties decided to collaborate to create a new version of HTML. Some rules established for HTML5: New features should be based on HTML, CSS, DOM and JavaScript. Reduce the need for external plug-ins (such as Flash) - many powerful multimedia tags are built-in Better error handling More tags to replace scripts HTML5 should be device independent - run perfectly on PC and mobile devices The development process should be transparent to the public Some interesting new features in HTML5: Canvas element for drawing Video and audio elements for media playback Better support for local offline storage New special content elements, such as article, footer, header, nav, section New form controls, such as calendar, date, time, email, url, search For more detailed information on HTML5, please refer to my blog topic: http://blog.csdn.net/column/details/dawanganban-html5.htmlLatest Versions of Safari, Chrome, Firefox, and Opera support certain HTML5 features. Internet Explorer 9 will support certain HTML5 features. 4. Global attributes in HTML5 The following global attributes can be used for any HTML5 element Attributes Description accesskey Specifies the keyboard shortcut to access the element class Specifies the class name of the element (used to specify the class in the style sheet). contenteditable Specifies whether users are allowed to edit content. contextmenu Specifies the context menu of the element. dir Specifies the text direction of the content in the element. draggable Specifies whether the user is allowed to drag the element. dropzone Specifies what happens when the dragged item/data is dropped into the element. hidden Specifies that the element is irrelevant.
