How can I make an accordion menu with CSS3?

问题

How can I create an expandable menu with only HTML5 and CSS3?

I want to display only 4 menu items and a view all list item, where clicking view all should expand all of the list items.

There are several ways to make it! For example the following. The HTML looks like this. There is a div, that you click and a div underneath that will expand. This is only possible with the pseudo-selector :target.

<div class="accordion">
    <div id="one" class="section">
            <h3>
                    <a href="#one">Heading 1</a>
            </h3>
            <div>
                    <p>Content</p>
            </div>
    </div>
    <div id="two" class="section">
            <h3>
                    <a href="#two">Heading 2</a>
            </h3>
            <div>
                    <p>Content</p>
            </div>
    </div>
</div>​




.accordion h3 + div {
        height: 0;
        overflow: hidden;
        -webkit-transition: height 0.3s ease-in;
        -moz-transition: height 0.3s ease-in;
        -o-transition: height 0.3s ease-in;
        -ms-transition: height 0.3s ease-in;
        transition: height 0.3s ease-in;
}

.accordion :target h3 + div {
        height: 100px;
}

.accordion .section.large:target h3 + div {
        overflow: auto;
}
