Answer 1

所以你想让标题背景颜色为红色？

然后就这样做。

<div class="heading" id="seamless" style="display: none; background: red;">

Answer 2

添加一个css规则（如果类标题仅用于此目的）

.heading {
   background-color: red;
}

如果没有添加新类并向其添加css规则

.newclass {
    text-align: center;
    background-color: red;
}

然后

<div class="heading newclass " id="seamless" style="display: none;">

Answer 3

在css中使用

.heading {
  background : red;
}
