有没有可能有一个div标签，它有1px的黑色边框和透明背景，所以只显示边框？这可能吗？有什么例子吗？

CSS：
div.emptybox {
border: 1px solid black;
background: transparent;
}
HTML：
<div class="emptybox">
Hello World
</div>

#someDiv { border:1px solid #000; }
<div id="someDiv">The div must either have some content, or else have the height and width specified in the CSS above.</div>
