伙计们,我遇到了一个问题,我正在做的是创建一个具有叠加效果的图像网格,它不仅仅是一个具有绝对位置的容器,当有人悬停在它上面时会有一些标题和文本。
网格每行只能有 3 张图像。一切正常,但我想根据叠加效果的父元素将标题和段落文本垂直居中。我知道我可以通过使用 flexbox 来做到这一点,但我想要浏览器兼容性,这就是我不使用 flexbox 的原因。有没有一种方法可以不使用 flexbox 来做到这一点?

最佳答案

是的,您可以使用 CSS positioning properties .将您想要居中的内容包裹在其自己的容器中,然后使用 position: absolute

*,
.row,
.col {
box-sizing: border-box;
}

body {
font: 1em/1.5 'Open Sans', sans-serif;
color: #373737;
background: #eaeaea;
}

h1,
h2,
h3 {
text-transform: uppercase;
}

h2 {
font-size: 1.125em;
color: #4a89ca;
font-weight: 600;
margin: 0;
}

h3 {
font-size: 1.3em;
line-height: 1.25em;
margin-top: .85em;
margin-bottom: .5em;
}

p {
font-size: .875em;
line-height: 1.4;
margin: 0 0 1.5em;
}

.container {
max-width: 1260px;
width: 94.02985075%;
background: #fff;
margin: auto;
}

.row:before,
.row:after {
content: " ";
display: table;
}

.row:after {
clear: both;
}

.row {
text-align: center;
margin-bottom: 10px;
}

.row:last-child {
margin-bottom: 0;
}

.col {
position: relative;
float: left;
display: block;
}

.col + .col {
margin-left: 1.6%;
}

.col-4 {
width: 32.2666666667%;
line-height: 0;
overflow: hidden;
}

.col-4 img {
max-width: 100%;
display: block;
background-color: #eaeaea;
}

.photo-overlay {
position: absolute;
left: 0;
padding-left: 20px;
padding-right: 20px;
top: 0;
bottom: 0;
right: 0;
color: #fff;
background-color: rgba(0, 0, 0, .5);
}

.photo-overlay {
opacity: 0;

}

.photo-overlay:hover {

/* NEW */
.photo-overlay:hover > div {

}
<div class="container">
<div class="row">
<div class="col col-4">

<div class="photo-overlay">
<div><!-- START NEW CONTAINER -->
<h3>Some Caption</h3>
<p>Aenean lacinia bibendum nulla sed consectetur. Fusce dapibus, tellus ac cursus commodo</p>
</div><!-- END NEW CONTAINER -->
</div>
</div>
</div>
</div>

下面是对这种居中方法的解释:

这是使用 vertical-align 和表格属性的另一种方法:
