        <div>
            <section>
                <h2><span>CSS3实现一些标题样式</span></h2>
                <div class="ribbon"><span class="ribbon1"><span>这是一台机器</span></span></div>
                <div class="ribbon"><span class="ribbon2">这<br />是<br />一<br />台<br />机<br />机器</span></div>
                <div class="ribbon"><span class="ribbon3">这是一台机器</span></div>
                <div class="ribbon"><span class="ribbon4">这是一台机器</span></div>
                <div class="ribbon"><span class="ribbon5">这是一台机器</span></div>
