i creating liquid layout example shown below using exact html example shown in book html , css jon duckett-

* {    font-family: arial, verdana, sans-serif;    color: #665544;    text-align: center;  }    body {    width: 90%;    margin: 0 auto;    min-width: 400px;  }    #content {    overflow: auto;  }    #nav,  #feature,  #footer {    margin: 1%;  }    .column1,  .column2,  .column3 {    width: 31.3%;    float: left;    margin: 1%;  }    .column3 {    margin-right: 0%;    /* no effect anyway float left */  }    li {    display: inline;    padding: 0.5em;  }    #nav,  #footer {    background-color: #efefef;    padding: 0.5em 0;  }    #feature,  .article {    height: 10em;    margin-bottom: 1em;    background-color: #efefef;  }
<!doctype html>  <html>    <head>    <title>liquid layout</title>  </head>    <body>    <div id="header">      <h1>logo</h1>      <div id="nav">        <ul>          <li id="home"><a href="">home</a></li>          <li><a href="">products</a></li>          <li><a href="">services</a></li>          <li><a href="">about</a></li>          <li id="contact"><a href="">contact</a></li>        </ul>      </div>    </div>    <div id="content">      <div id="feature">        <p>feature</p>      </div>      <div class="article column1">        <p>column one</p>      </div>      <div class="article column2">        <p>column two</p>      </div>      <div class="article column3">        <p>column three</p>      </div>    </div>    <div id="footer">      <p>&copy; copyright 2011</p>    </div>  </body>    </html>

when viewed in full screen, ul list isn't in centre of div. thought, centre div, should 2 things

  1. define width less container.
  2. set margin 0 auto

so, set ul element width 70% , margin 0 auto. result in snippet below produces strange result. 

		* {  			font-family: arial, verdana, sans-serif;  			color: #665544;  			text-align: center;  		}  		  		body {  			width: 90%;  			margin: 0 auto;  			min-width: 400px;  		}  		  		#content {  			overflow: auto;  		}  		#nav, #feature, #footer {  			margin: 1%;  		}  		.column1, .column2, .column3 {  			width: 31.3%;  			float: left;  			margin: 1%;  		}  		.column3 {  			margin-right: 0%;  			/* no effect anyway float left */  		}  		ul {  			width: 70%;  			margin: auto;  		}  		li {  			display: inline;  			padding: 0.5em;  		}  		#nav, #footer {  			background-color: #efefef;  			padding: 0.5em 0;  		}  		#feature, .article {  			height: 10em;  			margin-bottom: 1em;  			background-color: #efefef;  		}
<!doctype html>  <html>  <head>  	<title>liquid layout</title>  </head>  <body>  	<div id="header">  		<h1>logo</h1>  		<div id="nav">  			<ul>  				<li id="home"><a href="">home</a></li>  				<li><a href="">products</a></li>  				<li><a href="">services</a></li>  				<li><a href="">about</a></li>  				<li id="contact"><a href="">contact</a></li>  			</ul>  		</div>  	</div>  	<div id="content">  		<div id="feature">  			<p>feature</p>  		</div>  		<div class="article column1">  			<p>column one</p>  		</div>  		<div class="article column2">  			<p>column two</p>  		</div>  		<div class="article column3">  			<p>column three</p>  		</div>  	</div>  	<div id="footer">  		<p>&copy; copyright 2011</p>  	</div>  </body>  </html>

all of padding lost, , list still not centered. doing wrong?

you need add padding-left:0px; ul. style default web automatically provides -- add padding ul elements.

here's screenshot computer. chrome browser gives ul's default styling below.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
