我试图在这里得到嵌套的div#canvas(白色区域):填充100%的空白空间

以下是html:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title>Ontario Shores Foundation</title>
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
    <link href="../css/styles.css" rel="stylesheet" type="text/css" />
    <telerik:RadStyleSheetManager ID="RadStyleSheetManager1" runat="server">
    </telerik:RadStyleSheetManager>
</head>
<body>
    <form id="form2" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager3" runat="server">
        <Scripts>
            <%--Needed for JavaScript IntelliSense in VS2010--%>
            <%--For VS2008 replace RadScriptManager with ScriptManager--%>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
        </Scripts>
    </telerik:RadScriptManager>
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    </telerik:RadAjaxManager>
    <div id="wrapper">
        <div style="padding-top: 20px;">
            <div id="canvas">
                <div style="text-align: right; width: 100%;">
                    <uc3:LoginView ID="LoginView1" runat="server" />
                </div>
                <uc1:Header ID="Header1" runat="server" />
                <div id="content">
                    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
                    </asp:ContentPlaceHolder>
                </div>
            </div>
        </div>
        <div class="push">
        </div>
    </div>
    <uc2:Footer ID="Footer2" runat="server" />
    </form>
</body>
</html>

我最终使用jquery函数来增加div的高度

$(document).ready(function () {
    var h = window.innerHeight - 20 - 132; //padding and footer height
    if (h > $('div#canvas').height()) {
        $('div#canvas').height(h);
    }

});
我仍然认为有一个更干净的css解决方案来解决这个问题

$(document).ready(function () {
    var h = window.innerHeight - 20 - 132; //padding and footer height
    if (h > $('div#canvas').height()) {
        $('div#canvas').height(h);
    }

});
