拉伸和调整html对象的大小以适应?

标签: html css resize object-tag

我正在制作一个页面,用于同时显示4个对象。这些对象将流式传输实时视频,并在单击主菜单中的项目时动态分配。我需要的是帮助自动调整页面上的所有内容,以便在不滚动的情况下尽可能地进行拉伸。

enter image description here

黑匣子是页面。顶部的标题框始终具有相同的高度,左侧的框始终具有相同的宽度。然而,绿色框需要自动调整大小以尽可能地适合,并且所有4个都是相同的大小。除主菜单外,任何地方都不应有滚动条。

最重要的是,当内容框调整大小时,对象也需要调整大小。我在IE中看到了“100%”宽度的对象无法正常工作的问题。

如何构建此页面?我还是相当新的HTML,不知道如何设置它来调整大小。这是我到目前为止的代码:

更新

在尝试了Ana使用display: table;的答案后,我得到了更好的表现,但它现在仍在填补所有空间。页面也取决于主要的高度是800像素,我需要100% - 由于标题div我无法弄清楚如何做,由于主菜单宽度相同。那么我如何A)确保页面在没有滚动条的情况下正确拉伸,以及B)如何用每个框填充其内容?

[PS - 这个新代码中将找不到图像,现在是3x3而不是2x2]

答案 0 :(得分:5)

在绿色框上使用position: absolute;并将其直接放入contentmain。然后将它们定位如下:

#divContent1 {top:0;left:0;bottom:50%;right:50%}
#divContent2 {top:50%;left:0;bottom:100%;right:50%}
#divContent3 {top:0;left:50%;bottom:50%;right:100%}
#divContent4 {top:50%;left:50%;bottom:100%;right:100%}

此外,请勿对float:left;的对象使用width: 100%;。更好的是,甚至不在块元素上设置width:100%; - 块元素自然地扩展以水平填充其父元素。不要在所有内容上设置position: relative。保留默认值(position: static),只在需要时设置position: relative。就像你想要绝对定位的某些元素的父元素一样 - 你可能想要阅读这个http://css-tricks.com/absolute-relative-fixed-positioining-how-do-they-differ/

或其他版本:使用display: table; - 演示http://dabblet.com/gist/2815688
