Priority: External style
Priority, that is: the right side of the selector with the same name will cover the left side
1. Internal style sheet
<head> <style> /*内部样式表,一般用于覆盖公用样式*/ #headTip { color: 0xff5; } </style></head>
2. Use the link tag to declare the use of external resources in the document, the most commonly used a way.
The @CHARSET="utf-8"; that specifies the encoding of the css external style sheet needs to be placed on the first line.
<head> <link href="./my-common.css" rel="stylesheet" media="screen" type="text/css"/></head>
3.@ Method, introduce css. Note that this is loaded asynchronously. It is loaded after the entire html is loaded, which will cause the page to flicker. Not recommended.
<head> <style> @import 'my-common.css'; </style></head>
4. Inline style sheets have the highest priority and are the most straightforward, but they cannot be reused and are not easy to maintain.
<body> <input type="text" style="color:0x550;font-size:30px;"/></body>
