我有一个进度条

<div class="progress-bar-line red" role="progressbar"  
    aria-valuenow="redrated" aria-valuemin="0" aria-valuemax="100"
    ngStyle="max-width:{{redrated}}%"
>
    <span class="title">{{ redrated }}%</span>
</div>

字符串
我已经使用ngStyle="max-width:{{redrated}}%"并尝试过:
1.在组件中创建了一个对象,并以ng样式调用它
1.即使ngStyle="{'max-width': '20px' }"也给出了同样的错误,请帮助我解决这个问题

正确的语法是在键中定义像素,而不是在值中:

<div [ngStyle]="{'min-height.px':'700'}">
</div>
