“min-height”百分比仅在元素具有“display: flex”的间接父元素时适用
无法理解为什么 #inner
元素只有在 #main
得到 display:flex
规则时才具有其高度。
这是我的代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | #main {
display : flex
}
#wrapper {
background-color : violet
}
.content {
font-size : 2em
}
#inner {
min-height : 50% ;
background-color : green
}
|
1 2 3 4 5 6 7 8 | < div id = "main" >
< div id = "wrapper" >
< div class = "content" >Lorem Ipsum is simply dummy text of the printing and typesetting industry. </ div >
< div class = "content" >It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.</ div >
< div class = "content" >It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.</ div >
< div id = "inner" ></ div >
</ div >
</ div >
|
如果我删除 display: flex
规则 #inner
的高度等于 0:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | #main {
}
#wrapper {
background-color : violet
}
.content {
font-size : 2em
}
#inner {
min-height : 50% ;
background-color : green
}
|
1 2 3 4 5 6 7 8 | < div id = "main" >
< div id = "wrapper" >
< div class = "content" >Lorem Ipsum is simply dummy text of the printing and typesetting industry. </ div >
< div class = "content" >It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.</ div >
< div class = "content" >It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.</ div >
< div id = "inner" ></ div >
</ div >
</ div >

还有一件事。
当 #inner
内部有一些内容时,其高度将被累加为 #main
高度。
