标签: html css background background-image

我想制作一个带有背景图像的div,顶部将有3个社交媒体图标,如下所示:

我想要的是: what i wanted

div#second-footer-container {
  background-image: url("https://i.imgur.com/0qRwdSI.png");
  width: 100% !important;
  background-size: 100% 100%;
  background-repeat: no-repeat;
  height: 100%;
}

p#socmed-container {
  text-align: center;
}

p#socmed-container a {
  padding: 0 5px !important;
}
<div id="second-footer-container">
  <p id="socmed-container">
    <a href="https://www.facebook.com/test/">
      <img id="fb-img" width="25" src="https://i.imgur.com/6ye5lwf.png" alt="Facebook" />
    </a>
    <a href="https://www.instagram.com/test/">
      <img id="ig-img" width="25" src="https://i.imgur.com/SEsRzFL.png" alt="Instagram" />
    </a>
    <a href="https://www.twitter.com/test/">
      <img id="twitter-img" width="25" src="https://i.imgur.com/y8o23cc.png" alt="Twitter" />
    </a>
  </p>
</div>

但是结果看起来不是我想要的,我的结果是背景似乎只跟随主要内容的高度: result

我希望宽度为100%,高度也为100%,并且希望它具有响应性

使用background-size:contain

  

在不裁剪或拉伸图像的情况下尽可能放大图像。

background-size - reference

body,html{
  height: 100%;
}
div#second-footer-container {
  background-image: url("https://i.imgur.com/0qRwdSI.png");
  width: 100% !important;
  background-size: contain;
  background-repeat: no-repeat;
  height: 100%;
}

p#socmed-container {
  text-align: center;
}

p#socmed-container a {
  padding: 0 5px !important;
}
<div id="second-footer-container">
  <p id="socmed-container">
    <a href="https://www.facebook.com/test/">
      <img id="fb-img" width="25" src="https://i.imgur.com/6ye5lwf.png" alt="Facebook" />
    </a>
    <a href="https://www.instagram.com/test/">
      <img id="ig-img" width="25" src="https://i.imgur.com/SEsRzFL.png" alt="Instagram" />
    </a>
    <a href="https://www.twitter.com/test/">
      <img id="twitter-img" width="25" src="https://i.imgur.com/y8o23cc.png" alt="Twitter" />
    </a>
  </p>
</div>
