The html5 code is as follows:

 

By default, placeholder prompts the character autofocus. When the page is loaded, a focus button x-webkit-speech is obtained for Voice Search, the webkit kernel supports the types of files that can be uploaded according to accept (only applicable to type = file)

Alt specifies that the image input control replaces the text autocomplete and specifies whether to use the automatic completion function of the input field. The required input field is required. The interval pattrn between input numbers is used to perform regular matching on the input content.
