用纯CSS3实现网页中常见的小箭头,实现代码如下所示:
/* css3三角形(向上 ▲) */ p.arrow-up { width:0px; height:0px; border-left:5px solid transparent; /* 右透明 */ border-right:5px solid transparent; /*右透明 */ border-bottom:5px solid #2f2f2f; /* 定义底部颜色 */ font-size:0px; line-height:0px; } /* css3三角形(向下 ▼) */ p.arrow-down { width:0px; height:0px; border-left:5px solid transparent; border-right:5px solid transparent; border-top:5px solid #2f2f2f; font-size:0px; line-height:0px; } /* css3三角形(向左) */ p.arrow-left { width:0px; height:0px; border-bottom:5px solid transparent; /* left arrow slant */ border-top:5px solid transparent; /* right arrow slant */ border-right:5px solid #2f2f2f; /* bottom, add background color here */ font-size:0px; line-height:0px; } /* css3三角形(向右) */ p.arrow-rightright { width:0px; height:0px; border-bottom:5px solid transparent; /* left arrow slant */ border-top:5px solid transparent; /* right arrow slant */ border-left:5px solid #2f2f2f; /* bottom, add background color here */ font-size:0px; line-height:0px; }
