为了使问题更易于分析,我创建了this jsFiddle:
代码:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<style>
body {margin:0; }
#mainContainer { position: absolute; right: 4%; left: 4%; height: 100%; }
#headerContainer { width: 100%; z-index: 10; position: absolute; background: #323232; color: white; height: 30px; }
#middleContainer { height: 100%; }
#leftSection { position: absolute; float: left; width: 175px; background: #71ABD1; height: 100%; overflow: auto; color: black; padding-top: 30px; }
#middleSection { position: absolute; height: 100%; background-color: yellow; left: 175px; right: 175px; color: black; padding-top: 30px; }
#rightSection { float: right; height: 100%; width: 175px; border-left: 1px dotted black; background: red; color: black; padding-top: 30px; }
#footerContainer { position: absolute; bottom: 0; width: 100%; height: 30px; background: #323232; color: white; }
</style>
</head>
<body>
<div id="mainContainer">
<div id="headerContainer">
headerContainer
</div>
<div id="middleContainer">
<div id="leftSection">
leftSection
</div>
<div id="middleSection">
middleSection
</div>
<div id="rightSection">
rightSection
</div>
</div>
<div id="footerContainer">
footerContainer
</div>
</div>
</body>
</html>
使用顶部,中部和底部部分的标记,问题是:
1-正如您可以看到,尽管页脚div上有position:absolute
和bottom:0px
,但页面底部的页脚并不是真正的黑色
2-更重要的是,leftSection,middleSection和rightSection DIV与页眉和页脚DIV重叠,事实上,在这个小提琴中,查看3个中间部分显示的文本的唯一方法是放置填充以避免它显示在标题DIV下面。
我尝试在middleContainer上放置30px的顶部和底部值以修复重叠问题,但这并没有解决问题,我想要的是将headerContainer保持在顶部,将footerContainer保持在底部,而所有3个中间部分都调整为100%高度。 leftSection和rightSection具有固定的宽度,但middleSection具有灵活的宽度和高度。

“填充顶部:30px;”在你的3个内部元素上,它们比实际身体的高度高30px,造成你的问题。
从这3个元素中删除顶部填充,然后使页眉和页脚相对定位,而不是绝对,并且应该设置。

您的问题是您在headercontainer
和footercontainer
,solution
HTML:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<div id="mainContainer">
<div id="headerContainer">
headerContainer
</div>
<div id="middleContainer">
<div id="leftSection">
leftSection
</div>
<div id="middleSection">
middleSection
</div>
<div id="rightSection">
rightSection
</div>
</div>
<div id="footerContainer">
footerContainer
</div>
</div>
</body>
</html>
CSS:
body { margin:0; }
#mainContainer
{
position: absolute;
right: 4%; left: 4%;
height: 100%;
}
#headerContainer
{
width: 100%;
z-index: 10;
position: relative;
background: #323232;
color: white;
height: 30px;
}
#middleContainer { height: 100%; }
#leftSection
{
position: absolute;
float: left;
width: 175px;
background: #71ABD1;
height: 100%;
overflow: auto;
color: black;
padding-top: 30px;
}
#middleSection
{
position: absolute;
height: 100%;
background-color: yellow;
left: 175px;
right: 175px;
color: black;
padding-top: 30px;
}
#rightSection
{
float: right;
height: 100%;
width: 175px;
border-left: 1px dotted black;
background: red;
color: black;
padding-top: 30px;
}
#footerContainer
{
position: relative;
bottom: 0; width: 100%;
height: 30px;
background: #323232;
color: white;
}
回顾整个小提琴我注意到你在每个div
使用绝对定位。这是错误的。
你应该只在绝对定位时:
div
内使用div
,但这只有在父定位设置为relative
时才有效。答案 3 :(得分:0)
您可以删除所有3个
padding-top: 30px;
像
#leftSection { position: absolute; float: left; width: 175px; background: #71ABD1; height: 100%; overflow: auto; color: black; }
#middleSection { position: absolute; height: 100%; background-color: yellow; left: 175px; right: 175px; color: black; }
#rightSection { float: right; height: 100%; width: 175px; border-left: 1px dotted black; background: red; color: black; }
并像这样更改你的HTML
<div id="mainContainer">
<div id="headerContainer">
headerContainer
</div>
<div id="middleContainer">
<div id="leftSection">
<div style="margin-top:30px;">leftSection</div>
</div>
<div id="middleSection">
<div style="margin-top:30px;">middleSection</div>
</div>
<div id="rightSection">
<div style="margin-top:30px;">rightSection</div>
</div>
</div>
<div id="footerContainer">
footerContainer
</div>
</div>
我希望这会有所帮助。
