The meta tag in HTML5 and the hook that IE browser can recognize, html5meta
I. Use meta tags 1. Use the description attribute to increase the click rate

<meta name="description" content="A general guide on the use of meta tags in html pages" />

2. Set character sets

<meta charset="UTF-8" />

3. redirection and timed refresh

<! -- Refresh regularly every 5 seconds --> <meta http-equiv = "refresh" content = "5; url = http://www.sitepoint.com/"/>

4. adaptive device width (for mobile devices)

<Meta name = "viewport" content = "width = device-width, initial-scale = 1.0"> <meta name = "viewport" content = "width = device-width, initial-scale = 1, maximum-scale = 1, minimum-scale = 1, user-scalable = no "> content parameter: width viewport width (numeric value/device-width) height viewport height (numeric value/device-height) initial-scale initial scaling ratio maximum-scale maximum scaling ratio minimum-scale minimum scaling ratio user-scalable allow user Scaling (yes/no) minimal-ui iOS 7.1 beta 2 adds properties on the page Minimize the upper and lower status bars during loading. This is a Boolean value and can be written as follows: <meta name = "viewport" content = "width = device-width, initial-scale = 1, minimal-ui">

5. Use the highest mode rendering for IE

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

[Endif]-> 7. <! -[If lt IE 6]> versions earlier than IE6 and IE6 are recognizable <! [Endif]-> 8. <! -[If gte IE 6]> IE6 and IE6 or later versions are recognizable <!
