这是我的CSS
#snackbar {
float: bottom;
visibility: hidden;
min-width: 250px;
margin-left: -125px;
background-color: #009688;
color: #fff;
text-align: center;
border-radius: 2px;
padding: 16px;
position: fixed;
z-index: 1;
right: 5%;
top: 10%;
font-size: 17px;
}
#snackbar.show {
visibility: visible;
-webkit-animation: fadein 0.5s, fadeout 0.5s 2.5s;
animation: fadein 0.5s, fadeout 0.5s 2.5s;
}
@-webkit-keyframes fadein {
from {top: 0; opacity: 0;}
to {top: 10%; opacity: 1;}
}
@keyframes fadein {
from {top: 0; opacity: 0;}
to {top: 10%; opacity: 1;}
}
@-webkit-keyframes fadeout {
from {top: 10%; opacity: 1;}
to {top: 0; opacity: 0;}
}
@keyframes fadeout {
from {top: 10%; opacity: 1;}
to {top: 0; opacity: 0;}
}
是否可以更改typescript中的所有顶级值我需要使用@Input从html中给出最高值,是否可以使用角度2替换css“top”和css“bottom”?
您需要使用ngClass:
<some-element [ngClass]="{'first': true, 'second': true, 'third': false}">...</some-element>
我认为没有别的办法。在这里阅读更多关于ngClass的信息:https://angular.io/api/common/NgClass
