基础 5:将我的 img 大小设置为 div 的 100%

Foundation 5: Styling my img size to the be 100% of a div

我正在使用 Foundation 5 来设置一个基本页面。我正在尝试获取一个按钮来更改某个 div 的背景图像。到目前为止这是有效的,但它只显示图像的特定区域。

这是我目前的代码:

function cW() {
  document.getElementById("panel").style.backgroundImage =
    "url('https://dl.dropboxusercontent.com/u/36821301/csgo%20backgrounds/crimson-web.jpg')";
  document.getElementById("panel").backgroundImage.style.maxWidth = "100%";
}

<body>
  <div class="row">
    <div class="medium-12 columns">
      <div id="panel" class="panel">
        <h1>Foundation Page</h1>
        <p>Resize this responsive page to see the effect!</p>
        <ul class="button-group round">
          <li>
            <button type="button" class="button" value="cW" onclick="cW()">Crimson Web</button>
          </li>
          <li>
            <button type="button" class="button" value="mF" onclick="mF()">Marble Fade</button>
          </li>
          <li>
            <button type="button" class="button" value="d" onclick="d()">Doppler</button>
          </li>
          <li>
            <button type="button" class="button" value="rC" onclick="rC()">Rust Coat</button>
          </li>
          <li>
            <button type="button" class="button" value="dS" onclick="dS()">Damascus Steel</button>
          </li>
          <li>
            <button type="button" class="button" value="s" onclick="hB()">Hyper Beast</button>
          </li>
        </ul>
      </div>
    </div>
  </div>
</body>

</html>

我想达到的目标: 我想在某个 div.

范围内显示完整尺寸的图像

谢谢

您需要将 background-size 添加到 div 的 CSS。像

background-size: 100% 100%;

background-size: cover;

background-size: contain;

您必须尝试各种方式才能看到您想要哪一种。无论哪种方式,背景都会整齐地适合 div

希望对您有所帮助

在您的 css 文件中添加以下样式

 #panel{
    width:100vw;
    height:100vh;
  }
