I would like to ask how to achieve the following effect, move the mouse over the picture to show a complete text description

as shown in the picture, the effect is that the mouse moves over the picture, the picture is hidden, and the corresponding introduction is displayed. 

<li>
    <div><img src=""/></div>
    <div></div>
</li>
<li>
    <div><img src=""/></div>
    <div></div>
</li>

the method used now is to set the parent element li to position:relative;2 child elements to set absolute positioning position:absolute;, when the mouse moves over the parent element to change the child element zmuri index, the text part is displayed. But where there is a lot of text, it will be blocked by the following li element, which is only the size of the parent element, because the other li positioning is position:relative.

excuse me: how can the text display be completely unblocked when the mouse is moved up?

is it true that the width of a text box is twice as large as that of a picture box, and should be placed on top of it?
if yes, you need to change the previous layout.
as you said, set li to relative , then the text box inside will be obscured by the following elements.
so you can take a li as a whole row, that is, directly accommodate the first three li elements, and set it to relative . 

<ul>
  <li>
    <div>
      <div class="img-box"></div>
      <div class="info-box"></div>
    </div>
    <div>
      <div class="img-box"></div>
      <div class="info-box"></div>
    </div>
    <div>
      <div class="img-box"></div>
      <div class="info-box last"></div>
    </div>
  </li>
</ul>

<style>
  li {
    position: relative;
    width: 600px;
    height: 200px;
  }
  li>* {
    display: inline-block;
  }
  li .img-box {
    width: 200px;
    height: 200px;
    background: -sharpeee;
  }
  li .info-box {
    position: absolute;
    top: 0;
    width: 400px;
  }
  li .info-box.last {
    right: 0;
  }
</style>
