如何在页面中间添加标题文字?我使用flask-bootstrap,我想用我自己的CSS样式自定义它。
这是我的示例代码:
HTML
{% extends "bootstrap/base.html" %}
{% block head %}
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
{{ super() }}
<!-- My ccs style -->
<link rel="stylesheet" href="{{url_for('.static', filename='start.css')}}">
<!-- Custom Fonts -->
<link href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font- awesome.css" rel="stylesheet">
{% endblock %}
{% block content %}
<header class="header">
<div class="text-vertical-center">
<h1>Welcome to my Site</h1>
<h3>My portfolio</h3>
<br>
<a href="#" class="btn btn-dark btn-lg">Next Site</a>
</div>
</header>
{% endblock %}
CSS
html,
body {
width: 100%;
height: 100%;
}
body {
font-family: "Source Sans Pro","Helvetica Neue",Helvetica,Arial,sans-serif;
}
.text-vertical-center {
display: table-cell;
text-align: center;
vertical-align: middle;
}
.text-vertical-center h1 {
margin: 0;
padding: 0;
font-size: 4.5em;
font-weight: 700;
}
.btn-dark {
border-radius: 4;
color: #fff;
background-color: rgba(0,0,0,0.4);
}

为了以这种方式使用display: table-cell;
,父元素必须设置为display: table;
。在此之后它应该工作。
.header {
display: table;
}

我认为这会对你有帮助。
.text-vertical-center{
height: 100px;
width: 100px;
background-color: #036;
left: 0;
margin: auto;
position: absolute;
top: 0;
right: 0;
bottom: 0;
}
<div class="text-vertical-center">
<h1>Welcome to my Site</h1>
<h3>My portfolio</h3>
<br>
<a href="#" class="btn btn-dark btn-lg">Next Site</a>
</div>

如果您尝试将内容(垂直和水平)放置在页面的中心,则可以position: absolute
使用2D Transforms。
*您可能希望对较小的视口使用媒体查询,但无需正常工作。
工作示例:
html,
body {
width: 100%;
height: 100%;
}
body {
font-family: "Source Sans Pro", "Helvetica Neue", Helvetica, Arial, sans-serif;
}
.header .text-vertical-center {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
text-align: center;
background: red;
}
.header .text-vertical-center h1 {
margin: 0;
padding: 0;
font-size: 4.5em;
font-weight: 700;
}
.header .btn-dark {
border-radius: 4;
color: #fff;
background-color: rgba(0, 0, 0, 0.4);
}
@media (max-width: 800px) {
.header .text-vertical-center {
position: absolute;
top: 50%;
left: 0;
right: 0;
transform: translateY(-50%);
}
}
