  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>

<!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

	<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>
