街上经常碰到一些发各类广告传单的，有一次收到一张房地产广告的传单，顺手留下来，看着里面有些广告挺吸引人，同时也想练练自己css技术，故抽空做了一下。
原图某区域如下：
实现上图效果是需要一些想象力的，比如三角形的构成和左右两边的空白间距，懂的这个原理，然后熟练运用border属性，一切就OK了
比如其中一个三角形
<div class="arrow_ltitle1"> </div>
div.arrow_ltitle1 { width: 0; height: 0; border-top: 35px solid white; border-bottom: 35px solid white; border-left: 25px solid #68C339; }
HTML代码如下：
<div class="fl arrow_shadow"> <div class="arrow_lcontent1 fl"> <div style="margin-top: 10px"> <div> 低容积率</div> <div> <b style="font-size: 15pt">仅2.8</b></div> </div> </div> <div class="arrow_ltitle1 fl"> </div> <div class="arrow_rtitle1 fl"> <div class="arrow_rcontent1"> <div> 同样的地块，那里建了10栋楼，这里仅仅7栋，居住舒适度你懂得！</div> </div> </div> </div> <div class="fr arrow_shadow"> <div class="arrow_lcontent2 fl"> <div style="margin-top: 10px"> <div> 低建筑密度</div> <div> <b style="font-size: 12pt">仅23.51%</b></div> </div> </div> <div class="arrow_ltitle2 fl"> </div> <div class="arrow_rtitle2 fl"> <div class="arrow_rcontent2" style="margin-top: 8px"> <div> 最大栋距达到近200米，</div> <div> 视觉空间超乎想象！</div> </div> </div> </div> <div class="empty10"> </div> <div class="fl arrow_shadow"> <div class="arrow_lcontent3 fl"> <div style="margin-top: 13px"> <div> 建材用的贵</div> <div> 品质有保障</div> </div> </div> <div class="arrow_ltitle3 fl"> </div> <div class="arrow_rtitle3 fl"> <div class="arrow_rcontent3"> <div> 含钢量超出市场同类产品约30%，品质有保障，给您一个五星级的家。</div> </div> </div> </div> <div class="fr arrow_shadow"> <div class="arrow_lcontent4 fl"> <div style="margin-top: 5px"> <div> 临江</div> <div> 瞰岛</div> <div> 官佛</div> </div> </div> <div class="arrow_ltitle4 fl"> </div> <div class="arrow_rtitle4 fl"> <div class="arrow_rcontent4"> <div> 远离噪音污染，</div> <div> 与佛相伴修生养性；</div> <div> 上风上水财运滚滚！</div> </div> </div> </div> <div class="empty10"> </div> <div class="fl arrow_shadow"> <div class="arrow_lcontent5 fl"> <div style="margin-top: 5px"> <div> 贴近自然</div> <div> 畅想都市</div> <div> 慢生活</div> </div> </div> <div class="arrow_ltitle5 fl"> </div> <div class="arrow_rtitle5 fl"> <div class="arrow_rcontent5"> <div> 太阳岛一墙之隔，</div> <div> 大佛景区近在咫尺，</div> <div> 远离都市尾气生活！</div> </div> </div> </div> <div class="fr arrow_shadow"> <div class="arrow_lcontent6 fl"> <div style="margin-top: 13px"> <div> 买房装修</div> <div> 一步到位</div> </div> </div> <div class="arrow_ltitle6 fl"> </div> <div class="arrow_rtitle6 fl"> <div class="arrow_rcontent6"> <div> 四川家装连锁品牌芙蓉锦城提供多种精装套餐服务，实体样板呈现，恭迎品鉴</div> </div> </div> </div>
