HTML

 <div class = "content-container">
<h1 class = "main-header"> Connect with Subscribers Effortlessly </h1>
 <p class = "sub-header"> Email Marketing Platform for Bloggers & 
Authors. </p>
 </div>

CSS

 .content-container  .main-header{

  box-sizing: border-box;
  font-weight: 600;
  font-size: 45px;
  height:75px;
  padding-left: 5px;
  padding-right: 5px;
  color: rgb(51, 51, 51);
  font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
  border-style: solid;

}

.content-container .sub-header {
  border-style: solid;
  display: flex;
  height: 25px;
  margin-top: 150px;
}

Answer 1

如果您移除margin-top规则中的.content-container .sub-header并将flex-direction: column; align-items: center;添加到.content-container，则文字将正确居中

* {
  box-sizing: border-box;
}

.header-container {
  display: flex;
  width: 100%;
  height: 100px;
  align-items: center;
  justify-content: space-between;
  padding-left: 50px;
  padding-right: 75px;
}

.header-container .logo {
  width: 250px;
}

.header-container .logo .sb {
  max-width: 100%;
}

.header-container .nav-bar-container {
  display: flex;
}

.nav-link {
  text-decoration: none;
  color: #4B4B4B;
  font-weight: bold;
  font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
  font-size: 14px;
  padding: 15px;
}

.content-container {
  width: 100%;
  height: 300px;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  border-style: solid;
  margin-top: 15px;
}

.content-container .main-header {

.content-container .sub-header {
  border-style: solid;
  display: flex;
  height: 25px;
}


/* Resize window to see its effect */

@media( max-width: 700px) {
  .header-container {
    flex-direction: column;
  }
}

<div class="header-container">
  <a class="logo"> <img class="sb" src="logo.png" alt="logo"> </a>
  <nav class="nav-bar-container">
    <a class="nav-link" href="#"> Tour </a>
    <a class="nav-link" href="#"> Pricing </a>
    <a class="nav-link" href="#"> Medium </a>
    <a class="nav-link" href="#"> Sign Up </a>
    <a class="nav-link" href="#"> Login </a>
  </nav>
</div>

<div class="content-container">
  <h1 class="main-header"> Connect with Subscribers Effortlessly </h1>
  <p class="sub-header"> Email Marketing Platform for Bloggers & Authors. </p>
</div>

如果您打算将.content-container .sub-header w / o考虑在内，请考虑.content-container .main-header，您需要定位.content-container .main-header绝对

有了这个，它将与我在第一个解决方案中添加的flex-direction: column;一起使用或没有。{/ p>

请注意，在较宽的屏幕上，您需要调整两者，否则它们会重叠

Updated codepen

在.content-container .main-header

中添加了这些属性

position: absolute;
top: 0;
left: 0;
right: 0;
text-align: center;

Answer 2

你只需做两件事。

1。添加

flex-direction: column;
align-items: center;

到你的.content-container班。

2。从margin-top: 150px移除.content-container .sub-header，应该是它。

* {
  box-sizing: border-box;
}

.content-container {
  width: 100%;
  height: 300px;
  display: flex;
  justify-content: center;
  border-style: solid;
  margin-top: 15px;
  flex-direction: column;
  align-items: center;
}

.content-container .main-header {
  box-sizing: border-box;
  font-weight: 600;
  font-size: 30px;
  height: 75px;
  padding-left: 5px;
  padding-right: 5px;
  color: rgb(51, 51, 51);
  font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
  border-style: solid;
}

.content-container .sub-header {
  border-style: solid;
  height: 25px;
}

＆＃13;

<div class="content-container">
  <h1 class="main-header"> Connect with Subscribers Effortlessly </h1>
  <p class="sub-header"> Email Marketing Platform for Bloggers & Authors. </p>
</div>
