问题描述
我在这里很困惑.既然body是100%(宽/高)，main-container也是100%(宽/高)，那为什么还有垂直滚动?
我创建了一个 jsFiddle 来解释这种情况:http://jsfiddle.net/dcnnvgs1/1/
body,html {宽度:100%；高度:100%；font-family: "Trebuchet MS !important";背景色:#00b3b3；}.主容器{显示:弹性；弹性方向:列；flex-wrap: nowrap;高度:100%；宽度:100%；box-sizing: 边框框；}.main-header {背景色:#099；高度:10%；}.main-footer {背景色:#099；高度:10%；}.main-content {背景色:#fff;高度:100%；}<div class="main-container"><div class="main-header">HEADER</div><div class="main-content">jecechejbhcbjbcjrbjb bbjbhbbk</div><div class="main-footer">FOOTER</div>谢谢各位
解决方案
body 标签默认有一个边距取决于浏览器，例如在 chrome 中它的 margin:8px你必须通过它来休息
body{保证金:0;}查看更新的fiddle
I am very much confused here. Since the body is 100% (width/height) and main-container is also 100% (width/height), why is there vertical scroll?
I created a jsFiddle to explain the situation: http://jsfiddle.net/dcnnvgs1/1/
body,
html {
width: 100%;
height: 100%;
font-family: "Trebuchet MS !important";
background-color: #00b3b3;
}
.main-container {
display: flex;
flex-direction: column;
flex-wrap: nowrap;
height: 100%;
width: 100%;
box-sizing: border-box;
}
.main-header {
background-color: #099;
height: 10%;
}
.main-footer {
background-color: #099;
height: 10%;
}
.main-content {
background-color: #fff;
height: 100%;
}
<body>
<div class="main-container">
<div class="main-header">HEADER</div>
<div class="main-content">jecechejbhcbjbcjrbjb bbjbhbbk</div>
<div class="main-footer">FOOTER</div>
</div>
</body>
Thanks guys

the body tag by default has a margin depend on the browser as example in chrome its margin:8pxyou have to rest it via

}
