带有粘性页脚的100%高度内容<div> </div>

标签: css height sticky-footer

我需要一个固定的高度标题,一个固定的高度页脚,以及夹在其间的100%高度div(它持有整页背景图像)。我正在使用粘性页脚,因为这是一个模板,也可用于具有可能溢出的常规内容的页面(没有背景图像)。这适用于常规页面,但在需要100%高度容器的页面上,它会失败。我无法将100%高度div扩展到100%。任何帮助将不胜感激。

这是测试页面,显示我在100%高度div时遇到的问题:http://www.dunnandtigheinteriors.com/new/wp-content/themes/dunntighe/testhome.html

html, body {
    margin: 0;
    padding: 0;
    height: 100%;
}
body {
    font-family: Georgia, Times, "Times New Roman", serif;
    background: #EFEFEF;
    font-size: 14px;
}
#wrapper {
    min-height: 100%;
/*    height: 100%;
    position: relative;  Required to absolutely position the footer 
    text-align: center;*/
}
#headerHolder {
    width: 100%;
    background: #FFFFFF;
    height: 50px;
}
#bkgHolder {
    width: 100%;
    height: calc(100% - 100px);
    background: #DEDFE1;
    padding-bottom: 25px;
    background-image: url('images/DunnTigheWhiteOverlay.png');
    background-repeat: no-repeat;
    background-position: center; 
    background-size: auto 100%;
    overflow:auto;
    padding-bottom: 25px; /* must be same height as the footer */
}
#footerHolder {
    text-align: center;
    font-size: 10px;
    height: 25px;
    color: #888888;
    background-color: #0074a2;
/*    position: absolute;*/
/*    bottom: 0;  Sit it on the bottom 
    left: 0;*/
    width: 100%; /* As wide as it's allowed */
    position: relative;
    margin-top: -25px;
    clear:both;
}
#footerHolder p {
    padding: 5px 0 0 0;
    margin: 0;
}
#pageText {
    overflow:auto;
    padding-bottom: 25px; /* must be same height as the footer */
}
.pageContent {
    text-align: left;
    width: 680px;
    margin: 0 auto;
    padding-bottom: 15px;
}

你总是可以这样做吗?

最后一个答案令人费解。让我确定一下它的作用:

查看此处:http://jsfiddle.net/SinisterSystems/8aLg3/9/

  • 位于页面顶部的静态标题
  • 将保留在页面底部的静态页脚
  • 实现了jQuery函数,该函数将在窗口上调整大小并调整大小,将图像大小调整为当前约束,而不会破坏纵横比。
  • BG Image将固有地居中。

对此javscript解决方案并不理想,但要求您完成此任务。


HTML:

<div id="bkgHolder"></div>

<div class="wrapper">
    <div id="header">
        <h1>I'm the Sticky Header</h1>
    </div>
    <div id='content'>
        <p>Some content here</p>
    </div>
</div>

<footer class="footer">
  I'm the Sticky Footer.
</footer>

CSS:

* {
  margin: 0;
}
html, body {
  height: 100%;
}
#header {
    background:#CCC;
    height:50px;
}
#bkgHolder {
    background-image: url('http://www.hdwallpapers.in/walls/abstract_color_background_picture_8016-wide.jpg');
    background-repeat: no-repeat;
    background-position: center; 
    background-size:contain;
    width:100%;
    height:100%;
    position:absolute;
    margin-top:50px;
    z-index:-10;
}
.wrapper {
  min-height: 100%;
  margin-bottom: -25px; 
  position:relative;
}
.wrapper:after {
  content: "";
  display: block;
}
.footer, .wrapper:after {
  height: 25px; 
}
.footer {
  background:#6AF;
}
p {
    color:#FFF;
}

jQuery脚本添加:

$(function() {
    var h = $(window).height();
    var w = $(window).width();
    $('#bkgHolder').css({
        'width': w,
        'max-height': h-75,
    });
    window.onresize = function(event) {
        h = $(window).height();
        w = $(window).width();
        $('#bkgHolder').css({
            'width': w,
            'max-height': h-75,
        });
    } 
});
