html - 隐藏的溢出不适用于图像

Question

我试过使用 overflow: hidden;对于每个元素，但它似乎没有做任何事情

html 看起来像这样，显示是并排放置 2 个 div(对于较小的屏幕，堆叠在顶部)。左侧的 div 也将位于右侧的 div 之上。我也有屏幕截图和 fiddle 。

.sec {
  background-color: red;
  min-height: 100vh;
  overflow: hidden;
}

.sec2 {
  background-color: blue;
  min-height: 100vh;
  overflow: hidden;
}

.img1 {
  max-width: 100%;
  position: absolute;
}

.img1 {
  z-index: 1;
}

.leftCol {
  z-index: 10;
  width: 50%;
}

.info-row {
  display: flex;
  flex-direction: row;
  margin-left: 10vw;
  margin-right: 200px;
}

.rightCol {
  width: 50%;
}

<section class="sec">
  <div class="info-row">
    <div class="leftCol info-column">
      <h1>haheaheh</h1>
      <p>teataetetat</p>
    </div>
    <div class='rightCol info-column'>
      <img class="img1" src='https://kasonbloom.files.wordpress.com/2017/08/lamb-2.jpg' />
    </div>
  </div>
</section>

<section class="sec2">
  <div class="info-row">
    <div class="leftCol info-column">
      <h1>asdfasdfasdf</h1>
      <p>basfbasdfbasdfba</p>
    </div>
    <div class='rightCol info-column'>
    </div>
  </div>
</section>

Add position:relative; to your outer section .sec and it will work fine.

.sec {
  background-color: red;
  min-height: 100vh;
  overflow: hidden;
  position:relative;
}

.sec2 {
  background-color: blue;
  min-height: 100vh;
  overflow: hidden;
}

.img1 {
  max-width: 100%;
  position: absolute;
}

.img1 {
 z-index: 1;

}

.leftCol {
  z-index: 10;
  width: 50%;
}

.info-row {
  display: flex;
  flex-direction: row;
  margin-left: 10vw;
  margin-right: 200px;
}

.rightCol {
    width: 50%;
}

<section class="sec">
  <div class="info-row">
    <div class="leftCol info-column">
      <h1>haheaheh</h1>
      <p>teataetetat</p>
    </div>
    <div class='rightCol info-column'>
      <img class="img1" src='https://kasonbloom.files.wordpress.com/2017/08/lamb-2.jpg' />
    </div>
  </div>
</section>

<section class="sec2">
  <div class="info-row">
    <div class="leftCol info-column">
      <h1>asdfasdfasdf</h1>
      <p>basfbasdfbasdfba</p>

    </div>
    <div class='rightCol info-column'>
    </div>
  </div>
</section>
