【问题描述】：
我在另一个div#zinc.container-fluid 中有一个div.container。我使用通常的flexbox 方法使用justify-content 和align-items 属性，但这似乎不起作用......我猜这是position: absolute 的东西。
这是我所有的代码：
body {
font-family: Montserrat, sans-serif;
font-weight: 200;
}
.navbar {
border-style: none;
border-radius: 0;
background-color: transparent;
}
.navbar .navbar-header [type="button"].navbar-toggle {
border-style: none;
border-radius: 0;
}
.navbar .navbar-header .navbar-brand {
color: #C70039;
}
.navbar .navbar-collapse {
border-style: none;
border-radius: 0;
}
.navbar .navbar-collapse ul {
background-color: #FF5733;
}
.navbar .navbar-collapse ul a {
color: #fff;
}
#zinc {
background-color: blue;
color: #fff;
position: absolute;
width: 100%;
height: 100%;
display: flex;
justify-content: center;
align-items: center;
}
#zinc #subtitle {
font-size: 24px;
}

</html>如何将div.container 置于div#zinc 的中心？
附：请注意我在我的项目中使用的是 Bootstrap 3。

块已经居中。你的意思是在块内居中文本？使用
text-align: center。 -
好像居中了吧？
