前几天用css3实现了一些基本的泡沫对话框，今天在原来的原理的基础上做了一些复杂的。
html代码如下
<div class="content">
<p class="triangle-border">This only needs one HTML element.</p>
<p class="triangle-border top">For example, <code><p>[text]</p></code>.</p>
<p class="triangle-border left">But it could be any element you want.</p>
<p class="triangle-border right">The entire appearance is created only with CSS.</p>
<h2>Simple examples</h2>
<h3 class="example-commentheading">125 comments</h3>
<blockquote class="example-right">
<p>Design is directed toward human beings. To design is to solve human problems by identifying them and executing the best solution.</p>
</blockquote>
<p>Ivan Chermayeff</p>
<blockquote class="example-obtuse">
<p>It’s not what you look at that matters, it’s what you see.</p>
</blockquote>
<p>Henry David Thoreau</p>
<blockquote class="example-twitter" cite="/necolas/status/9880187933">
<p>Takes me longer to write up blog posts on experiments or projects than to create them in the first place.</p>

<h2>More complex CSS3 examples</h2>
<p>Some more experimental speech bubbles that try to limit the damage in browsers lacking the necessary CSS3 support.</p>
<div class="pinched">
<p><strong>It doesn’t matter what the first child element of this div is</strong>...but it does need a child element.</p>
</div>
<blockquote class="oval-speech">
<p>This is a blockquote that is styled to look like a speech bubble</p>
</blockquote>
<blockquote class="oval-thought">
<p>This is a blockquote that is styled to look like a thought bubble</p>
</blockquote>
</div>
