Ret*_*ros 1 html css twitter-bootstrap bootstrap-4
我正在制作一张 Bootstrap 4 卡片,它的标题需要有一个图像、标题、副标题、徽章和一个关闭按钮。并且徽章需要在右侧垂直居中,而图像、标题和副标题需要在左侧垂直居中。
这是一张图片,它会更好地解释事情:
而且我无法获得标题和副标题,也无法获得垂直居中的徽章。我必须仅使用 Bootstrap 实用程序来执行此操作,因此如果可能的话,不需要额外的 CSS(或者如果没有其他选择,则很少)。我怎样才能做到这一点?
这是我的代码:
.close {
font-size: 20px;
text-shadow: none;
color: #000;
opacity: 1;
position: absolute;
right: 0;
top: 0;
}
.card-title {
font-size: 18px;
}
.card-subtitle {
font-size: 11px;

使用Bootstrap 4 中的flexbox 实用程序类。如果您不熟悉,这里有一个很好的 flexbox 指南。
下面代码中添加的类是d-flex justify-content-between align-items-center,但您还需要一个带有自己类的标题和副标题的新包装器。
