Currently, most browsers support HTML5. However, some lower version browsers have some problems with HTML5 support.
Lower version browsers support HTML5
all browsers, and unrecognizable elements will be automatically processed as inline elements. Therefore, you can use the following method to teach the browser to handle "unknown" HTML elements.
Defining HTML5 elements as block elements
HTML5 defines 8 new HTML semantic elements. All these elements are block-level elements.
In order to allow older versions of browsers to display these elements correctly, you can set the display attribute of CSS to block:
header, section, footer, aside, nav, main, article, figure { display: block;
}Add new Element The following example adds a new element to HTML and defines a style for the element. The element name is : <!DOCTYPE html><html><head><meta charset="utf-8">
<title>为 HTML 添加新元素</title>
<script>document.createElement("myElement")</script>
<style>
myElement{
display: block;
background-color: #ddd;
padding: 50px;
font-size: 30px;
}
</style>
</head>
<body>
<h1 id="我的第一个标题">我的第一个标题</h1>
<p>我的第一个段落。</p>
<myElement>我的第一个新元素</myElement>
</body>
</html>
We can use the "HTML5 Enabling
JavaScript", "shiv" created by Sjoerd Visscher to solve this problem:
<!--[if lt IE 9]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]-->or
<!--[if lt IE 9]> <script src="http://apps.bdimg.com/libs/html5shiv/3.7/html5shiv.min.js"></script> <![endif]-->The above code is , when the IE browser version is smaller than IE9, the html5.js file will be read and parsed. The former one is the national Google resource, and the latter one is the domestic Baidu resource. For The following is an example of using the html5shiv solution:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>渲染 HTML5</title> <!--[if lt IE 9]> <script src="http://apps.bdimg.com/libs/html5shiv/3.7/html5shiv.min.js"> </script> <![endif]--></head><body><h1 id="我的第一个HTML-页面">我的第一个HTML5页面</h1> <article>Hello，world！</article> </body> </html>
