我有一张简单的表格:
<body>
<div class="wrapper">
<div class="board">
<div class="line">
<div class="position"></div>
<div class="position"></div>
<div class="position"></div>
</div>
<div class="line">
<div class="position"></div>
<div class="position"></div>
<div class="position"></div>
</div>
<div class="line">
<div class="position"></div>
<div class="position"></div>
<div class="position"></div>
</div>
</div>
</div>
</div>
</body>
用这个Css:
.wrapper {
width: 80%;
height: 80%;
margin: auto;
}
.board {
background-color: #37392e;
display: table;
table-layout: fixed;
width: 100%;
height: 100%;
}
.line {
display: table-row;
}
.position {
background-color: #DDCECD;
display: table-cell;
width: 33%;
}
当我指定尺寸和高度时,div不显示。我不会在div中使用文本,而是在他们的css“background”属性中显示图像。如何强制表元素遵循以%表示的大小。

将body,html高度设置为100%,然后您就可以使用board
中%
div的高度
高度为%的工作代码:
html,
body {
height: 100%;
min-height: 100%;
}
.wrapper {
width: 80%;
height: 80%;
margin: auto;
}
.board {
background-color: #37392e;
display: table;
table-layout: fixed;
width: 100%;
height: 100%;
}
.line {
display: table-row;
}
.position {
background-color: #DDCECD;
display: table-cell;
width: 33%;
}

这是因为正文高度等于零且0的80%仍为0.您需要为包装器设置特定高度,您可以使用HTML5 vh
单位将其设置为视图的80%端口。
.wrapper {
width: 80%;
height: 80vh;
margin: auto;
}

如果要使用百分比(%)的高度,则需要设置父级高度。只需在body和html标签上添加100%的高度。
html, body{
height: 100%;
}
.wrapper {
width: 80%;
height: 80%;
margin: auto;
}
.board {
background-color: #37392e;
display: table;
table-layout: fixed;
width: 100%;
height: 100%;
}
.line {
display: table-row;
}
.position {
background-color: #DDCECD;
display: table-cell;
width: 33%;
}
