NgStyle
一个属性指令,用于更新容器元素的样式。可以通过指定用冒号分隔的键值对来设置一个或多个样式属性。其键是样式名称,带有可选的 <unit>
后缀(比如 'top.px','font-style.em');其值是待求值的表达式。如果求值结果不是 null,则把用指定单位表示的结果赋值给指定的样式属性;如果是 null,则删除相应的样式。
An attribute directive that updates styles for the containing HTML element. Sets one or more style properties, specified as colon-separated key-value pairs. The key is a style name, with an optional .<unit>
suffix (such as 'top.px', 'font-style.em'). The value is an expression to be evaluated. The resulting non-null value, expressed in the given unit, is assigned to the given style property. If the result of evaluation is null, the corresponding style is removed.
