Question

如果我在bb类css代码之前移动代码，intro-block类背景颜色将为红色，但是如果我将其放在intro-block类css代码之后，则颜色不是改变，没有任何反应！有人能告诉我为什么会这样吗？！

.left-column {
  width: 35%;
  margin-left: 20px;
  margin-right: 50px;
  float: left;
  overflow: hidden;
}

.right-column {
  overflow: hidden;
}

.intro-block {
  background-color: #22AAA1;
  margin: 0 auto;
  /*max-width: 950px;*/}
}

.bb {
  background-color: red;
}

<body>
  <header>
    <section class="intro-block">
      <div class="left-column">
        <img class="profile-pic right-column" src="img/11.jpg">
      </div>
      <div class="right-column">
        <h1>lorem ipsum</h1>
        <p>
          <h4>lorem ipsum</h4>
        </p>
      </div>
    </section>
  </header>
  <main>
    <section class="bb">
      <h3>lorem ipsum</h3>
      <div class="left-column">
        <div>
          <p>lorem ipsum</p>
        </div>
      </div>
      <div class="right-column">
        <h5>lorem ipsum</h5>
      </div>

之前还有一个额外的}

注意：请勿在{{1}}

中打包标题（.bb {}至h1）

你应该缩进/整理你的代码以便更好地阅读，并且你会很容易发现这个错误

h6

Answer 2

/ max-width：950px; / }

你引用的行后面有一个额外的}，它与以下规则混淆了......
