我无法使用垂直对齐:中间样式垂直对齐按钮内的文本,该样式用于引导按钮中文本和图标的垂直对齐

<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">

</div>
<div class="col-md-3">

这是我的代码:

.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;
}
<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>
此外,代码截图和代码笔中的结果也不同。怎么会这样?
只需在 h3 标签上使用margin:0 auto
即可。
.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"/>
<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>
vertical-align:middle
对我也不起作用。我最终使用了flex。
在 Bootstrap 4 中,这只是使用 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>
如果你仍然坚持使用 Bootstrap 3,你可以创建自己的类:
.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,这两种情况都需要从 h3 标签中删除边距。
上边距:20px;在类 H3 中将其向下推。尝试使用 F12 工具进行故障排除。
你在<button>
里面使用<h3>
,不是"正确的",删除<h3>
并在".btn
"类中添加"font-size: 24px;
"。
