我如何给div响应高度 [英] how do I give a div a responsive height

问题描述

我要学习响应式设计，但是到目前为止，我似乎还没有发现一件事...

I'm stating to learn responsive design, but there's one thing I can't seem to figure out, so far...

这是一个工作示例: http://ericbrockmanwebsites.com/dev1/

我希望div元素(contactBg)的内部文本向下到图像底部.显然，我可以通过以px为单位定义高度来做到这一点，但是当窗口的其余部分重新调整大小而不是保持流畅时，便会保持该高度.

I'd like the div element (contactBg) with text inside of it to come down to the bottom of the image to the left. Obviously I can do that by defining the height in px, but then that height is maintained when the rest of the window resizes instead of being fluid.

如果您有任何好的文章可以解释如何做到这一点，那将非常有帮助，谢谢！

If there are any good articles out there you may know of that explains how to do this, that would be very helpful, thanks!

这是标记:

<div class="row-fluid">
        <div class="span10 offset1">
            <div class="container-fluid">
                <div class="row-fluid">
                    <div class="span5">
                        <img src="images/logo.jpg" alt="logo" />
                        <img src="images/store.jpg" alt="store" />
                    </div><!-- /span5 -->
                    <div class="span7">
                        <img src="images/portal.jpg" alt="portal">
                        <div class="contactBg">

                        </div><!-- /contactBg -->
                    </div><!-- /span7 -->
                </div><!-- /row-fluid -->
            </div><!-- /container-fluid -->
        </div><!-- /span10 offset1 -->
    </div> <!-- /row-fluid -->

这是CSS:

   body {
        background: url(../images/3D2A1698A177AF9B71_218.png) repeat;
    }

    img {
        max-width:100%;
        padding-bottom:1%;
    }

     .container-fluid {
        background:#fff;
        padding: 1%;
    }

      .row-fluid {
        width: 100%;
        *zoom: 1;
 }
      .row-fluid [class*="span"] {
        display: block;
        float: left;
        width: 100%;
        min-height: 30px;
        margin-left: 1%;
        *margin-left: 2.709239449864817%;

                box-sizing: border-box;
}

      .row-fluid .span10 {
        width: 82.87292817679558%;
        *width: 82.81973668743387%;
      }

      .row-fluid .span7 {

        *width: 57.12912895262725%;
      }

      .row-fluid .span5 {

推荐答案

我知道这晚了一点，但是您可以使用视口单位

I know this is a little late to the party but you could use viewport units

来自caniuse.com:

From caniuse.com:

视口单位:vw，vh，vmin，vmax-CR 长度单位代表视口大小的1％，即视口宽度(vw)，高度(vh)，两者中的较小者(vmin)或两者中的较大者(vmax).

Viewport units: vw, vh, vmin, vmax - CR Length units representing 1% of the viewport size for viewport width (vw), height (vh), the smaller of the two (vmin), or the larger of the two (vmax).

支持: http://caniuse.com/#feat=viewport-units

div {
/* 25% of viewport */
  height: 25vh;
  width: 15rem;
  background-color: #222;
  color: #eee;
  font-family: monospace;
  padding: 2rem;
}

<div>responsive height</div>
