html - 我怎样才能让我的侧边栏正确 float ？

Question

所以这让我发疯。在过去的两天里，我一直在努力让我的侧边栏向右浮动，但它一直出现在页面底部!答案可能很简单，但我似乎无法自己弄清楚...也许你们中的一个可以帮助我!

#wrap { 
	width: 1200px;
	/*margin: 0 auto;*/
	background-color:#e6fdff;
	color:#185358;
	padding:0;
}
#content {
	float:left;
	clear:right;
	padding:50px;
	padding-bottom:80px;
	/*margin:0 auto;*/
	right:250px;
}
#sidebar {
	float:right;
	width:300px;
}
#sidebar ul {
	list-style:none;
}
#sidebar ul a {
	text-decoration:none;
	font-family:'Crushed', cursive;
	color:#4B3C27;
}
#footer {
	width:100%;
	height:60px;
	position:fixed;
	bottom:0;
	left:0;
	border:1px solid #4B323F;
	border-width:1px 0;
	background-color:#E6FDFF;
}

<div id="wrap">
			<!--<div style="clear:both;"></div>-->
			<div id="content">
				<h2>Welcome to The Life of Esther!</h2>

首先需要从content div中取出sidebar，修改一些样式。请在此处查看更新代码 http://jsfiddle.net/w8gek7u8/

并查看下面的代码:

<style>
    #wrap { 
        width: 1200px;
        /*margin: 0 auto;*/
        background-color:#e6fdff;
        color:#185358;
        padding:0;
    }
    #content {
        float:left;
        clear:right;
        padding:50px;
        padding-bottom:80px;
        width:900px;
    }
    #sidebar {
        float:right;
        width:150px;
    }
    #sidebar ul {
        list-style:none;
    }
    #sidebar ul a {
        text-decoration:none;
        font-family:'Crushed', cursive;
        color:#4B3C27;
    }
    #footer {
        width:100%;
        height:60px;
        position:fixed;
        bottom:0;
        left:0;
        border:1px solid #4B323F;
        border-width:1px 0;
        background-color:#E6FDFF;
    }
    <style>

和 HTML 作为

<div id="wrap">
            <!--<div style="clear:both;"></div>-->
            <div id="content">
                <h2>Welcome to The Life of Esther!</h2>
