Question

我正在尝试使用css来填充我的表单/背景图像以占用整个屏幕，此时背景图像在底部被切除，表单没有完全占据屏幕上的所有空间相反，屏幕底部和顶部有空白区域。

以下是整个代码段。

</html>

Answer 1

从html标签中删除display：table并从css中的body标签中显示：table-cell。因为这个，身体居中在html标签中，这会在两侧产生空白。

Answer 2

将css更改为：

html {
    width: 100%;
    height: 100%;

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

form{
  position absolute;
  top: 0;
  left: 0;
  bottom:0;
  right: 0;
  overflow-y: auto;
  background: url('http://i.imgur.com/qhn5HDG.png');
  background-repeat:no-repeat;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

Answer 3

浏览器有自己的默认填充和边距。所以你必须使它们等于零。

for i in range(df_full.size):
    df_full[i] = df1[df_full.T == df1.T]

请告诉我这是否是你想要的。

html / css适合移动设备的整个屏幕
