我的页面上有两个图像,一个是封面(.big-cover),另一个是卡片。当我添加卡时,封面图像缩小。我无法弄清楚原因。
var app = angular.module('StarterApp', ['ngMaterial']);
app.controller('AppCtrl', ['$scope', '$mdDialog',
function($scope, $mdDialog) {}
])
.controller('DialogController', function($scope, $mdDialog) {});

md-toolbar p {
font-size: 1.250em;
font-weight: 200;
margin: auto;
}
md-toolbar {
min-height: 30px;
}
.a133 {
background: blue;
}
.a666 {
background: red;
}
.big-cover {
background: url(http://wallpapers.wallhaven.cc/wallpapers/full/wallhaven-277559.jpg) center center;
background-repeat: no-repeat;
background-position: center;
height: 45vh;
}
.change-cover {
text-transform: capitalize;
}
