block的高度是从最上面撑开的
那么inline-block呢？
直接上代码
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<style>
#test {
line-height: 0;
font-size: 80px;
background-color: gray;
}
#test span {
display: inline-block;
background-color: red;
height: 1px;
width: 150px;
}
#s1 { }
#s2 {
line-height: 1;
}
</style>
</head> <body>
<div style="height: 100px;"></div>
<div id="test">
<span id="s0"></span>
<span id="s1">33</span>
<span id="s2">33</span>
</div>
</body>
</html>
看到没？3个inline-block的撑开位置是不一样的。
同时把他们的父元素撑开了。
把3个inline-block高度加高试试
#test span {
display: inline-block;
background-color: red;
height: 10px;
width: 150px;
}撑开方向也不一样。
把span换成button试一试
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<style>
#test {
line-height: 0;
font-size: 80px;
background-color: gray;
}
#test button {
//display: inline-block;
line-height: 0;
font-size: 80px;
background-color: red;
height: 1px;
width: 150px;
}
#s1 { }
#s2 {
line-height: 1 !important;
}
</style>
</head> <body>
<div style="height: 100px;"></div>
<div id="test">
<button id="s0"></button>
<button id="s1">33</button>
<button id="s2">33</button>
</div>
</body>
</html>
height是1的时候跟span差不多的表现
增加height之后：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<style>
#test {
line-height: 0;
font-size: 80px;
background-color: gray;
}
#test button {
//display: inline-block;
line-height: 0;
font-size: 80px;
background-color: red;
height: 30px;
width: 150px;
}
#s1 { }
#s2 {
line-height: 1 !important;
}
</style>
</head> <body>
<div style="height: 100px;"></div>
<div id="test">
<button id="s0"></button>
<button id="s1">33</button>
<button id="s2">33</button>
</div>
</body>
</html>
中间元素的撑开方向与span不一样了
