我无法使用vertical alignment of text and icon in bootstrap button
中使用的vertical-align:middle样式垂直对齐按钮内的文本<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<body>
<div class="page-header">
<div class="row">
<div class ="col-md-3">
<h3 class="text-center" id="title">Kartikey</h3>
</div>
<div class ="col-md-1 col-md-offset-3" >
<button type="button" class="btn btn-default" ><h3 style="vertical-align:middle;">About</h3></button>
</div>
<div class="col-md-1">
<button type="button" class="btn btn-default"><h3 style="vertical-align:middle;">Portfolio</h3></button>
</div>
<div class="col-md-1">
<button type="button" class="btn btn-default"><h3 style="vertical-align:middle;">Contact</h3></button>
</div>
<div class="col-md-3">
</div>
</div>
</div>
</body>
这是我的code:
http://codepen.io/kartikeykant/pen/VPeWYN
.page-header{
height: 100px;
background-color: rgb(112, 137, 142);
margin-top: 0px;
}
#title{
font-size:400%;
color: white;
}
.btn{
margin-top:24px;
margin-right:50px;
margin-left:50px;
width:110px;
height:55px;
}
&#13;
<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<body>
<div class="page-header">
<div class="row">
<div class ="col-md-3">
<h3 class="text-center" id="title">Kartikey</h3>
</div>
<div class ="col-md-1 col-md-offset-3" >
<button type="button" class="btn btn-default" ><h3 style="vertical-align:middle;">About</h3></button>
</div>
<div class="col-md-1">
<button type="button" class="btn btn-default"><h3 style="vertical-align:middle;">Portfolio</h3></button>
</div>
<div class="col-md-1">
<button type="button" class="btn btn-default"><h3 style="vertical-align:middle;">Contact</h3></button>
</div>
<div class="col-md-3">
</div>
</div>
</div>
</body>
&#13;
此外,代码snipppet和codepen中的结果也不同。怎么回事?

只需在h3代码上使用.page-header{
height: 100px;
background-color: rgb(112, 137, 142);
margin-top: 0px;
}
#title{
font-size:400%;
color: white;
}
.btn{
margin-top:24px;
margin-right:50px;
margin-left:50px;
width:110px;
height:55px;
}
.btn h3{
margin:0 auto;
}
。
<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>

保证金最高:20px;在课堂上,h3将其推倒。尝试使用F12工具对其进行故障排除。
答案 2 :(得分:0)
您在<h3>
内使用<button>
,“不正确”,删除<h3>
并在“font-size: 24px;
”类中添加“.btn
”。
.page-header{
height: 100px;
background-color: rgb(112, 137, 142);
margin-top: 0px;
}
#title{
font-size:400%;
color: white;
}
.btn {
margin-top:24px;
margin-right:50px;
margin-left:50px;
width:110px;
height:55px;
font-size: 24px;
}
<head>
</head>
<body>
<div class="page-header">
<div class="row">
<div class ="col-md-3">
<h3 class="text-center" id="title">Kartikey</h3>
</div>
<div class ="col-md-1 col-md-offset-4" >
<button type="button" class="btn btn-default" >About</button>
</div>
<div class="col-md-1">
<button type="button" class="btn btn-default">Portfolio</button>
</div>
<div class="col-md-1">
<button type="button" class="btn btn-default">Contact</button>

答案 3 :(得分:0)
vertical-align:middle
也不适合我。我最终使用了flex。
在Bootstrap 4中,这仅是使用flex类的问题:
<div class="col-md-1">
<button type="button" class="btn btn-default d-flex align-items-middle justify-content-center">
<h3 class="m-0">Contact</h3>
</button>
</div>
如果您仍然对Bootstrap 3感兴趣,可以创建自己的课程:
CSS:
.valign-content {
display:flex;
align-items: center;
justify-content: center;
}
.valign-content>h3 {
margin:0;
}
HTML
<div class="col-md-1">
<button type="button" class="btn btn-default valign-content">
<h3>Contact</h3>
</button>
</div>
请注意,在两种情况下,您都需要从h3标签中删除边距。
