Question

我想在div内放置一个图像（紫色，见下图），其尺寸以％表示，并且该图像永远不会离开div，而是在需要时调整大小，并保持宽高比。< / p>

目前，我的代码如下，但是图像来自div，如下面的图片所示。

html {
  min-height: 100vh;
  position: relative;
}

body {
  height: 100vh;
  overflow: hidden;
}

#grille {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  overflow: hidden;
  flex-direction: row;
  display: flex;
  background-color: red;
}

#colonne {
  width: calc(100% / 3);
  height: 100%;
  background-color: green;
}

#cellule {
  flex-direction: column;
  width: 100%;
  height: calc(100% / 3);
  background-color: aqua;
}

#conteneurImage {
  width: 100%;
  height: 80%;
  background-color: violet;
}

#conteneurImage img {
  width: 100%;
  height: auto;
}

<!DOCTYPE html>
<html>

<head>
  <link rel="stylesheet" href="table.css" />
</head>

<body>
  <div id="grille">
    <div id="colonne">
      <div id="cellule">
        <div id="conteneurImage">
          <img src="home.png">
        </div>
        <div id="conteneurTexte">
          Accueil
        </div>
      </div>
    </div>
  </div>
  <script type="text/javascript">
  </script>
</body>

结果：

Answer 2

您可以在#conteneurImage中使用“ display：flex; justify-content：center;”。然后使用“ width：auto; height：100％;”在#conteneurImageImage img中。您可以在https://css-tricks.com/snippets/css/a-guide-to-flexbox/

body {
  height: 100vh;
  overflow: hidden;
}

#grille {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  overflow: hidden;
  flex-direction: row;
  display: flex;
  background-color: red;
}

#colonne {
  width: calc(100% / 3);
  height: 100%;
  background-color: green;
}

#cellule {
  flex-direction: column;
  width: 100%;
  height: calc(100% / 3);
  background-color: aqua;
}

#conteneurImage {
  width: 100%;
  height: 80%;
  background-color: violet;
  display:flex;
  justify-content: center;
}

#conteneurImage img {
  width: auto;
  height: 100%;

  #conteneurImage img {            
                display: block;
                width: 100%;
