html - 使 div 固定在另一个 div 之上的底部

我一直在开发带有水平滚动条的移动布局。

但是现在我遇到了一个问题:

页面底部有一个 NAV 元素，没问题，但我想在顶部和底部实现“软木板”的效果，并带有相应的“框架”。再一次，顶部的完全没有问题，但我在试图让底部的保持在底部并高于 NAV 栏时遇到了很多麻烦。

事情是这样的: enter image description here

基本上，红色方 block 是当前 View /屏幕，导航栏固定在底部，如果我滚动到另一个部分，它会按预期停留在屏幕底部，顶部蓝色条(顶部框架)也是如此).

如何使底部的蓝色条保持在预期/示例的位置？

我已经尝试了所有方法，包括边距、填充、高度和最小高度，但无法达到预期的效果。谁能指出我做错了什么？

最佳答案

如果我没看错，问题是背景卡在元素的顶部而不是底部？

将 background-position: bottom; 添加到该元素的样式中。

编辑以添加我的解决方案 css:

  • HTML 与原始帖子没有变化
  • “Meyerweb”CSS 保持不变
  • 更改的 CSS:
html, body { 
    height: 100%;
    overflow: hidden;
}
body {
    overflow-x: auto;
    /* allows that horizontal scrolling */
}

#wrapper {  
    width: 350%; 
    position: absolute;
    top: 0px;
    bottom: 0px;
    /* ^-- these three lines replace height:100%
     * and correct some layout quirks */
}
#wrapper > section { 
    display: inline-block; 
    height: 100%;
    margin-left: -4px;
    margin-bottom: -4px;
}

#wrapper > section:first-child  {
    margin-left: 0px;
    /* combined with -4px margin above, eliminates gaps between sections */
}

#wrapper > section, section > header, section > div {
    width: 25%;
    /* not sure why 25%, since you seem to only
     * have three sections... but either way,
     * the same value is needed in multiple locations
     * so it's pulled out on its own here for
     * ease of maintenance  */
}

section > header {
    position: absolute;
    top: 0px;
    height: 3em;
}
section > div {
    position: absolute;
    top: 0px;
    height: 100%;
    padding-top: 3em;
    padding-bottom: 3em; 
    box-sizing: border-box;
}

section#splash { /*unchanged*/
    background: url("../img/bg_grey.png") repeat;
}
section#next { /*unchanged*/
    background: url("../img/cork.jpg") repeat;
    z-index: 1;

section#next > header#frame-top { /*unchanged*/

    background-position: top;
    z-index: 3;

    /* Let's enforce some hardware acceleration */
    -webkit-transform: translate3d(0, 0, 0);
    -webkit-backface-visibility: hidden;
}

nav {
    bottom: 0;
    left: 0;
    position: fixed;
    background: -webkit-gradient(
        linear,
        left bottom,
        left top,
        color-stop(0.3, #303030),
        color-stop(0.5, #212121),
        color-stop(0.7, #575657)
    );
    background: linear-gradient(to top, #303030 30%, #212121 50%, #575657 70%);
    /* ^-- for non-webkit */
    height: 3em;
    width: 100%;
    z-index: 5;
}

nav ul { /*unchanged*/
    width:  50%;
    height: 100%;
    color: #FFF;
    margin-right: auto;
    margin-left: auto;
}

nav ul li{ /*unchanged*/
    width: 25%;
    height: 100%;
    display: inline-block;
}
