如何将我的文本和图像放在 div 的中间？

Question

我有 4 行不同的两列，一列有图片，另一列有文本。由于文本和图像的大小不同，我希望它们垂直居中。

这是我的其中一列的代码和该 div 的 CSS

.col2 {
  float: left;
  width: 46%;
  padding: 2%;
  text-align: center;
  position: relative;
  justify-content: center;
  height: 300px;
}

<div class="col2">
        <img src="images/freelance.png" alt="three people watching a presentation">
</div>
<div class="col2">
    <h2>Work as a Freelancer</h2>
    <p>This session will set out the key points you need 
       to consider when taking on freelance work in order to make
       sure you gain maximum professional and personal benefit.</p>
    <div class="book">
        <a class="booked" href="#" target="_blank"><p><b>Book 14th March 6pm</b></p></a>
    </div>
</div>

This is the before with my code

This is with @N3v4da Stone 's changes

Answer 1

N3v4da 的解释确实有效，但我会尝试更详细地说明。

Wrapper div 使用 flexbox 来连续显示元素。

align-items: center; 沿 flex 行垂直居中项目（这意味着文本与图像居中）

justify-content: space-between 将 img 和 div 元素放在包装器 div 的相对两侧。

gap: 20px 确保img 和div 之间始终存在 20px 的间隙

.wrapper {
  display: flex;
  align-items: center;
  justify-content: space-between;
  gap: 20px;
  
  background-color: lightblue;
}

.wrapper img {
  width: 300px;
  height: 300px;
}

<div class="wrapper">

        <p><b>Book 14th March 6pm</b></p>
      </a>
    </div>
  </div>
</div>

确保删除任何可能干扰此代码的 CSS，这可能是 N3v4da 的版本不起作用的原因。 This is what my solution does

Answer 2

使用容器和 flexbox CSS 来包装你的 col。 如果不正确，可能会像这样，提供您想要的图像。

.flex-container {
        display: flex;
        flex-flow: row wrap;
        justify-content: space-between;
        align-items: center;
     }

   .col2 {
      width: 46%;
      padding: 2%;
      text-align: center;
  }

 <div class="flex-container">
       <div class="col2">
