让IE(ie6/ie7/ie8)支持HTML5元素,我们需要在HTML头部添加以下JavaScript,这是一个简单的document.createElement声明,利用条件注释针对IE来调用这个js文件。Opera,FireFox等其他非IE浏览器就会忽视这段代码,也不会存在http请求。
方式一:引用google的html5.js文件,代码内容可以自己下载下来看。
<!–[if lt IE9]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]–>
将以上代码放到head标签区间
方式二:自己coding JS搞定。
<script> (function() { if (! /*@cc_on!@*/ 0) return; var e = "abbr, article, aside, audio, canvas, datalist, details, dialog, eventsource, figure, footer, header, hgroup, mark, menu, meter, nav, output, progress, section, time, video".split(', '); var i= e.length; while (i--){ document.createElement(e[i]) } })() </script>
不管你用上面哪中方式,请记得在CSS中进行如下定义,目的是让这些标签成为块状元素,just like div。
/*html5*/ article,aside,dialog,footer,header,section,footer,nav,figure,menu{display:block}
再结合那篇让ie6\7\8支持css3的,是不是世界美好了许多?

The alt attribute is an important part of the tag in HTML and is used to provide alternative text for images. 1. When the image cannot be loaded, the text in the alt attribute will be displayed to improve the user experience. 2. Screen readers use the alt attribute to help visually impaired users understand the content of the picture. 3. Search engines index text in the alt attribute to improve the SEO ranking of web pages.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML is used to build web page structure; 2. CSS is used to beautify the appearance of web pages; 3. JavaScript is used to achieve dynamic interaction. Through tags, styles and scripts, these three together build the core functions of modern web pages.

Setting the lang attributes of a tag is a key step in optimizing web accessibility and SEO. 1) Set the lang attribute in the tag, such as. 2) In multilingual content, set lang attributes for different language parts, such as. 3) Use language codes that comply with ISO639-1 standards, such as "en", "fr", "zh", etc. Correctly setting the lang attribute can improve the accessibility of web pages and search engine rankings.
