这就是 div 当前的样子

如您所见 style属性放置 background-color属性为

style="box-sizing: border-box; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); background-color: rgb(232, 232, 232); 

但是，我想要不同的颜色，但我无法更改此 div直接，所以我添加了一个 CSS class叫toolbar看起来像

.toolbar {
    background-color: #37517e;
    color: #ffffff;
}

从div可以看出上面的代码。然而，背景颜色来自 .toolbar被忽略，并且来自 style 的那个被申请;被应用。我在DevTools中确认了这一点

如何应用我选择的颜色？

Answer 1

在 css 属性中使用了 !important

.toolbar {
    background-color: #37517e!important;
    color: #ffffff;
}

.rowTest{
 background-color:pink!important;
}

<div style="background-color:green;width:100%;height:50px;" class="rowTest"><div>
