我在下面有以下 div 和 h2 元素。我试图用蓝色填充整个 div，而不是像我期望的那样填充整个 container2 类，它只填充 h2 部分。为什么要这样做以及如何填充整个 container2 部分(在 h2 区域之外有一些边距和填充？
h2 {
color: white;
font-size: 35px;
font-weight: 500;
}
.container2 {
text-align: center;
font-family: Carnas-Light;
background-color: #0f2c4d;
margin-top: 40px;
margin-bottom: 40px;
padding-right: 15px;
padding-left: 15px;
width: 83.33333333%;
margin-left: 8.33333333%;
height: 100%;
} <div class="container2">
<h2>WorkWave provides intuitive cloud-based field service & fleet management solutions that help organizations with a mobile workforce transform their business.</h2>
</div>最佳答案
只需将下一个样式代码添加到您的样式表中:
.container2 > h2 {
background-color: #0f2c4d;
}
你的方法行不通，因为你只为父元素 container2 设置了 BG-color，而不是为 h2 使用继承和元素。
运行代码:
h2 {
color: white;
font-size: 35px;
font-weight: 500;
}
.container2 {
text-align: center;
font-family: Carnas-Light;
background-color: #0f2c4d;
padding-top: 40px;
padding-bottom: 40px;
padding-right: 15px;
padding-left: 15px;
width: 83.33333333%;
margin-left: 8.33333333%;
height: 100%;
}
.container2 > h2 {
background-color: #0f2c4d;
