如何切换div以使用CSS显示内容

Question

所以我有一个div应该扩展以显示切换时的列表.在这里可以看到前后状态http://reversl.net/box/但是我需要添加到我的样式中才能实现这一点？我想使用css过渡来增加效果.我并不担心浏览器兼容性,因为它仅用于学习目的.有小费吗？

<div class="box"><img src="http://www.placehold.it/250x300" alt="" />
        <div class="section progress">
            <h4>
                <a href="#">Div Before</a>
            </h4>
            <div class="metrics">
                <div class="meter">
                    <span style="width: 75%"></span>
                </div><!--.meter-->
            </div><!--.metrics-->
        </div><!--.section-progress-->
</div><!--.box-->

<div class="box"><img src="http://www.placehold.it/250x300" alt="" />
        <div class="section progress">
            <h4>

            </h4>
            <div class="metrics">
                <div class="meter">
                    <span style="width: 75%"></span>
                </div><!--.meter-->
            </div><!--.metrics-->
        </div><!--.section-progress-->
        <div class="sub_section">
            <ul class="list">
                <li>Item 1</li>
                <li class="last">Item 2</li>

我担心我无法解决您的示例代码和图像,您想要点击的内容以及您想要显示的内容.但是,以下onclick使用纯CSS 的-like事件:

<div id="wrapper">
    <ul id="top">
        <li><a href="#one">One</a></li>
        <li><a href="#two">Two</a></li>
    </ul>
    <div class="box" id="one">
        <p>One</p>
        <span><a href="#top">Close</a></span>
    </div>
    <div class="box" id="two">
        <p>Two</p>
        <span><a href="#top">Close</a></span>
    </div>
</div>

CSS:

.box {
    position: absolute;
    top: 20%;
    left: 50%;
    width: 50%;
    margin-left: -25%;
    border: 4px solid #000;
    background-color: #f90;
    /* the CSS, above, is all for aesthetic purposes, what matters is the following */
    opacity: 0;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    -0-transition: all 1s linear;
    transition: all 1s linear;
}

.box:target {
    opacity: 1;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    -0-transition: all 1s linear;
    transition: all 1s linear;
}

不幸的是,似乎(在Chromium 17/Ubuntu的11.04),不可能从动画display: none;到display: block;同样的转变,从height: 0以height: auto也失败(在突然出现的,而不是一个过渡试图要么结果.所以,在演示的内容始终是"有",但简单地隐藏(使用不透明度),然后在单击相关链接后显示.

但是对于滑动切换效果:

.box {
    /* aesthetic stuff excised for brevity */
    opacity: 0;
    height: 0;
    overflow: hidden;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    -0-transition: all 1s linear;
    transition: all 1s linear;
}

.box:target {
    opacity: 1;
    height: 3em;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    -0-transition: all 1s linear;
    transition: all 1s linear;
}
