CSS三角形广告文字_html/css_WEB-ITnose

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>
