要将文本居中置于图像上，不需要FlexBox。 只需使用CSS定位属性。
.height-100vh {
height: 100vh;
position: relative; /* establish nearest positioned ancestor for
absolute positioning */
}
.text {
position: absolute;
left: 50%; /* horizontal alignment */
top: 50%; /* vertical alignment */
transform: translate(-50%, -50%); /* precise centering; see link below */
}
null
body {
margin: 0px;
}
.height-100vh {
height: 100vh;
display: flex; /* establish flex container */
flex-direction: column; /* stack flex items vertically */
position: relative; /* establish nearest positioned ancenstor for absolute positioning */
}
.text {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
color: white;
font-weight: bold;
}
.center-aligned {
display: flex;
align-items: center;
justify-content: center;
}<section class="height-100vh center-aligned">

<div class="text">SOME TEXT</div>

您只需用 null相对定位内联块包装图像，并按如下方式给出文本:
* {margin: 0; padding: 0; list-style: none;}
.img-holder {position: relative; display: inline-block;}
.img-holder img {display: block;}
.img-holder p {position: absolute; top: 50%; left: 0; right: 0; transform: translate(0, -50%); text-align: center; color: #fff; text-shadow: 0 0 15px;}<div class="img-holder">
<img src="http://bit.ly/1YrRsis" alt="">
<p>Text Aligned Centrally Vertical & Horizontal.</p>
</div>
我添加了另一个wrapperdiv来包围img和文本，并使用flex来定位文本。 查看此代码n
HTML:
<section class="height-100vh center-aligned">
<div class="wrapper">
<img class="background-image" src="http://bit.ly/1YrRsis" />
<div class="text">SOME TEXT</div>
</div>
</section>
CSS:
@import "bourbon";
body {
margin: 0px;
}
.height-100vh {
height: 100vh;
}
.center-aligned {
@include display(flex);
@include align-items(center);
@include justify-content(center);
}
.wrapper {
position: relative;
}
.text {
justify-content: center;
align-items: center;
display: flex;
color: #fff;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
}
