HTML Learning Note 4: Document declarations and coding tags

① Document DeclarationFunction: In order for the browser to display HTML files better, you must inform the browser of your file as HTML syntax:<! DOCTYPE html>

• The declaration must be placed in the first line of the HTML document
• Declaration is not an HTML tag

Ii Coded LabelsIf you do not set the encoding type correctly, garbled characters are displayed when you need to display a character that is not a browser-set encoding type

Workaround:

1. Use the <meta/> tag to set the encoding type in the
2. The <meta/> element provides meta-information about the page, which contains information about the corresponding HTML, and the client browser or server-side program processes its properties based on this information:

• HTTP-EQUIV, like the HTTP header protocol, will respond to the browser with some useful information that has helped to better display
• Contents (content type), such as content= "text/html"
• CharSet (encoding type), contained in content, such as content= "Text/html;charset=utf-8"

3. Full version <meta http-equiv= "Content-type" content= "Text/html;charset=utf-8"/>
