目前,越来越多的网站使用HTML5进行开发,本文提供了10段HTML5代码,它们可以帮你快速启动HTML5项目。

随着HTML5的流行,许多网站开始介绍HTML5元素和属性的用法,以及各种教程,并且越来越多老的浏览器开始兼容HTML5。

本文作者编译了10段非常实用的HTML5代码片段,开发者可以直接拿过去使用,帮你快速完成HTML5项目的开发工作,你也可以把它们当做一个学习资源,进行参考。

1.HTML5编写的CSS Reset

CSS Reset也可以写成Reset CSS,即重设浏览器样式。

/*   html5doctor.com Reset Stylesheet (Eric Meyer's Reset Reloaded + HTML5 baseline)  v1.4 2009-07-27 | Authors: Eric Meyer & Richard Clark  html5doctor.com/html-5-reset-stylesheet/*/html, body, div, span, object, iframe,h1, h2, h3, h4, h5, h6, p, blockquote, pre,abbr, address, cite, code,del, dfn, em, img, ins, kbd, q, samp,small, strong, sub, sup, var,b, i,dl, dt, dd, ol, ul, li,fieldset, form, label, legend,table, caption, tbody, tfoot, thead, tr, th, td,article, aside, figure, footer, header, hgroup, menu, nav, section, menu,time, mark, audio, video {margin:0;padding:0;border:0;outline:0;font-size:100%;vertical-align:baseline;background:transparent;}article, aside, figure, footer, header,hgroup, nav, section { display:block; }nav ul { list-style:none; }blockquote, q { quotes:none; }blockquote:before, blockquote:after,q:before, q:after { content:''; content:none; }a { margin:0; padding:0; font-size:100%; vertical-align:baseline; background:transparent; }ins { background-color:#ff9; color:#000; text-decoration:none; }mark { background-color:#ff9; color:#000; font-style:italic; font-weight:bold; }del { text-decoration: line-through; }abbr[title], dfn[title] { border-bottom:1px dotted #000; cursor:help; }/* tables still need cellspacing="0" in the markup */table { border-collapse:collapse; border-spacing:0; }hr { display:block; height:1px; border:0; border-top:1px solid #ccc; margin:1em 0; padding:0; }input, select { vertical-align:middle; }/* END RESET CSS */

2.HTML5 Video with Flash Fallback

解释下该段代码,如果浏览器不支持HTML5视频播放,那么会自动跳回Flash播放。

<video width="640" height="360" controls>	<source src="__VIDEO__.MP4"  type="video/mp4" />	<source src="__VIDEO__.OGV"  type="video/ogg" />	<object width="640" height="360" type="application/x-shockwave-flash" data="__FLASH__.SWF">		<param name="movie" value="__FLASH__.SWF" />		<param name="flashvars" value="controlbar=over&image=__POSTER__.JPG&file=__VIDEO__.MP4" />		<img src="__VIDEO__.JPG" width="640" height="360" alt="__TITLE__"		     title="No video playback capabilities, please download the video below" />	</object></video>
3.HTML5 Starter页面

<!DOCTYPE HTML><html>	<head>		<meta charset = "utf-8">		<title></title>		<link rel="stylesheet" href="style.css">		<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>		<!--[if IE]><script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]-->		<script scr ="script/script.js"></script>	</head><body>     <header>       <nav>       </nav>    </header>    <footer>    </footer>  </body><html>
4.创建谷歌静态地图

<!DOCTYPE html><html lang="en"><head>	<meta http-equiv="content-type" content="text/html; charset=utf-8">	<meta name="viewport" content="width=device-width, initial-scale=1.0 maximum-scale=1.0, user-scalable=no" />	<title>Geo Location</title>	<style type="text/css" media="screen">		html{ height: 100%; }		body{ height: 100%; margin: 0; padding: 0; }		#map{ width: 100%; height: 100%; }	</style>		<!-- jQuery Min -->		<script type="text/javascript" charset="utf-8" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>		<!-- Google Maps -->		<script type="text/javascript" charset="utf-8" src="http://maps.google.com/maps/api/js?sensor=true"></script>		<script charset="utf-8" type="text/javascript">		mapWidth = screen.width;		mapHeight = screen.height;		$(document).ready(function(){			var geo = navigator.geolocation;			if( geo ){				//Used for Static Maps				geo.watchPosition( showLocation, mapError, { timeout: 5000, enableHighAccuracy: true } );			}			function createStaticMarker( markerColor, markerLabel, lat, lng ){				return "&markers=color:" + markerColor + "|label:" + markerLabel + "|" + lat + "," + lng;			}			function createStaticMap( position ){				var lat = position.coords.latitude;				var lng = position.coords.longitude;				var zoom = 20;				var sensor = true;				var img = $("<img>");					img.attr( { src: "http://maps.google.com/maps/api/staticmap?" +								"center=" +								lat + "," +								lng +								"&zoom=" + zoom +								"&size=" + mapWidth + "x" + mapHeight +								createStaticMarker( "blue", "1", lat, lng ) +								"&sensor=" + sensor } );					return img;			}			function showLocation( position ){				var lat = position.coords.latitude;				var lng = position.coords.longitude;				var latlng = new google.maps.LatLng( lat, lng );				$("#map").html( createStaticMap( position ) )			}			function mapError( e ){				var error;				switch( e.code ){					case 1:						error = "Permission Denied";					break;					case 2:						error = "Network or Satellites Down";					break;					case 3:						error = "GeoLocation timed out";					break;					case 0:						error = "Other Error";					break;				}				$("#map").html( error );			}		});		</script>	</head>	<body>		<div id="map">		</div>	</body></html>
5.纯HTML5 Starter模板

<!DOCTYPE html>	<html>		<head>			<meta charset="utf-8">			<title>Untitled</title>			<!--[if lt IE 9]>			<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>			<![endif]-->		</head>		<body>		</body>	</html>
6.HTML5页面结构

<!DOCTYPE HTML><html><head>        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />        <title>Your Website</title></head><body>        <header>                <nav>                        <ul>                                <li>Your menu</li>                        </ul>                </nav>        </header>        <section>                <article>                        <header>                                <h2>Article title</h2>                                <p>Posted on <time datetime="2009-09-04T16:31:24+02:00">September 4th 2009</time> by <a href="#">Writer</a> - <a href="#comments">6 comments</a></p>                        </header>                        <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.</p>                </article>                <article>                        <header>                                <h2>Article title</h2>                                <p>Posted on <time datetime="2009-09-04T16:31:24+02:00">September 4th 2009</time> by <a href="#">Writer</a> - <a href="#comments">6 comments</a></p>                        </header>                        <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.</p>                </article>        </section>        <aside>                <h2>About section</h2>                <p>Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>        </aside>        <footer>                <p>Copyright 2009 Your name</p>        </footer></body></html>
7.上下文菜单

8.HTML5 Datalist

<input name="frameworks" list="frameworks" /><datalist id="frameworks">	<option value="MooTools">	<option value="Moobile">	<option value="Dojo Toolkit">	<option value="jQuery">	<option value="YUI"></datalist>
9.从谷歌地图上获取路线

<form action="http://maps.google.com/maps" method="get" target="_blank">   <label for="saddr">Enter your location</label>   <input type="text" name="saddr" />   <input type="hidden" name="daddr" value="350 5th Ave New York, NY 10018 (Empire State Building)" />   <input type="submit" value="Get directions" /></form>
