Question

我试图制作一个php画廊，这就是为什么我需要一个好的面具，以后可以显示图片。我希望Mask不要大于屏幕大小。我的意思是，必须没有滚动，整个<body>只需要浏览器窗口的宽度和高度，以便<body>中的每个子对象都限制在浏览器的帧大小如果它溢出，它将会缩小。我已在max-width上使用max-height和<body>进行了尝试，但它无法正常工作。

以下是我的index.html文件的内容：

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
  <div id="mother">
    <div id="header">
      <div id="back-link">
        <a href="../">Home</a>
      </div>
      <div id="prev">
        <a href="">next picture</a>
      </div>
      <div id="next">
        <a href="">previous picture</a>
      </div>
      <div id="headline">
        <p class="h2">Our Galery</p>
      </div>
    </div>

    <!-- Content -->
    <div id="container-bild">
      <img src="./bilder/P1130079.JPG" id="img-bild" />
    </div>
  </div>
</body>
</html>

以下是我的style.css文件的内容：

body {
  max-width: 100%;
  max-height: 100%;
}

/* mother-container */
div#mother {
  max-width: 100%;
  max-height: 100%;
  margin: auto;
}

/* main-container */
#container-bild {
  max-width: 100%;
  max-height: 100%;
}

/* picture in main-container */
#img-bild {
  max-width: 100%;
  max-height: 100%;
  border: 1px solid #280198;
}

以下是它的外观截图：

Answer 1

要将高度和宽度设置为窗口（视口）大小的100％，请使用：

height: 100vh;//100% view height
width: 100vw;// 100% view width

＆＃13;

div {
  background-color: blue;
  height: 100vh;
  width: 100vw;
  position: absolute;
  top: 0;
  left: 0;
  color: white;
}

＆＃13;

<div>some content here</div>

＆＃13;

Answer 2

尝试：

html,
body {
  height: 100%;
}

body {
  overflow: hidden;
}

你知道你的画廊中有多少个子元素吗？如果元素的数量是静态的，您可以使用vw和vh单位在CSS中设置它们的尺寸。不涉及JavaScript，元素永远不会溢出你的身体。

Answer 3

我不确定这是否可以用css，它可能是。我用javascript解决了类似的问题：

window.top.innerHeight;

获取可用高度，排除了borwser的菜单栏等。看看我是如何做到的，我的问题是即使内容是空的，页脚应该在底部 - ＆gt;

    <script>
        for (i=0;i<document.getElementsByClassName('mnuHorizontal').item(0).children.length; i++)
        {

        resizecontainer();

        function resizecontainer()

在上面的示例中查找此函数 - ＆gt;

            dbh     =   document.getElementsByClassName('divbottom').length *
                        document.getElementsByClassName('divbottom').item(0).clientHeight;

            dbt     =   document.getElementsByClassName('divtop').length    *
                        document.getElementsByClassName('divtop').item(0).clientHeight;

            dbbl    =   document.getElementsByClassName('divblueline').length   *
                        document.getElementsByClassName('divblueline').item(0).clientHeight;

            decrh = dbh + dbt + dbbl;

            document.getElementsByClassName('divcontainer').item(0).style.minHeight = (avh - decrh) + 'px';
        }

Answer 4

提醒我未来的自我：

.book {
    margin: auto;
    width: 100vh;
    max-width: 100vw;
    min-width: 500px;
}

虽然这完全不相关，但对于链接，您可能希望使用类似的内容：

a[href^="#"] {
    text-decoration: none;
    color: black;
    background: url("http://www.yaml.org/spec/1.2/term.png") no-repeat bottom right;
}
a[href^="#"]:hover {
    text-decoration: underline;
    color: blue;
    background: none;
}

Answer 5

我的CSS解决方案是：

position: absolute;
width: 100%;
height: 100%;
overflow: hidden;

Answer 6

这很好。这将使您的图像不会沿宽度方向过大地生长，并且也将保持其比例。

img {
    max-width: 100%;
    height: auto;
}

如何在CSS中限制屏幕大小的最大宽度和高度？
