[英]vertical align two elements within a div
我有以下div:
<div class="transparent-panel">
<h3>We asked some of our supports the following questions</h3>
<a href="#" class="button btn btn-white-big video-button-two">WATCH VIDEO</a>
</div>
我希望文本和按钮在div中居中显示。 当前看起来像这样:
而且我没有运气到中心。 这是transparent-panel
div的CSS:
.transparent-panel {
padding: 40px 20px 40px 20px;
width: 100%;
height: 100%;
background: rgba(51, 153, 51, 0.7);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#75FFFFFF, endColorstr=#75FFFFFF)";
}
我尝试使用position: relative;
在div上,然后position: absolute;
在h3
和a
标签上,但这h3
。
如果有人可以帮助我,将不胜感激。 我正在使用Bootstrap 3。

一种方法是将面板包装在容器中,将背景色放在容器上,然后使用几行CSS将面板在容器内垂直居中:
HTML:
<div class="panel-container">
<div class="transparent-panel">
<h3>We asked some of our supports the following questions</h3>
<a href="#" class="button btn btn-white-big video-button-two">WATCH VIDEO</a>
</div>
</div>
CSS:
html,body {
height:100%;
}
.panel-container {
height:100%;
background: rgba(51, 153, 51, 0.7);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#75FFFFFF, endColorstr=#75FFFFFF)";
}
.transparent-panel {
padding: 40px 20px 40px 20px;
width: 100%;
text-align:center;
/* Code to vertically center below */
position: relative;
top: 50%;
transform: translateY(-50%);
}
我发现将容器div设置为display: table
并将内容包装在设置为display: table-cell
的内部div中很有用。
然后,您可以使用vertical-align
属性:
/* CSS used here will be applied after bootstrap.css */ .teachers-image { background-size: cover; height: 418px; color: #ffffff; } .transparent-panel { padding: 0 20px; display: table; width: 100%; height: 100%; background: rgba(51, 153, 51, 0.7); -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#75FFFFFF, endColorstr=#75FFFFFF)"; } .transparent-panel > div { display: table-cell; vertical-align: middle; } .btn-white-big { background-color: #ffffff; height: 50px; color: #339933; font-size: 18px; font-weight: 500; line-height: 30px; @include add-border(3px, white, all); @include border-radius(30px); &:hover, &:focus, &.focus { background-color: #339933 !important; color: white; } }
<div class="teachers-image"> <div class="transparent-panel"> <div> <h3>We asked some of our supports the following questions</h3> <a href="#" class="button btn btn-white-big video-button-two">WATCH VIDEO</a> </div> </div> </div>
使用具有“查看高度”的容器从上到下居中:
height: 100vh;
视图高度将始终使用窗口显示高度。
HTML:
<div class="container">
<div class="transparent-panel">
<h3>We asked some of our supports the following questions</h3>
<a href="#" class="button btn btn-white-big video-button-two">WATCH VIDEO</a>
</div>
</div>
CSS:
.container {
height: 100vh;
background: rgba(51, 153, 51, 0.7);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#75FFFFFF, endColorstr=#75FFFFFF)";
}
.transparent-panel {
width: 100%;
text-align:center;
position: relative;
top: 50%;
}
