HTML中利用div+CSS实现简单的箭头图标的代码

/*箭头向上*/
.to_top {
    width: 0;
    height: 0;
    border-bottom: 10px solid #ccc;
    border-left: 10px solid transparent;
    border-right: 10px solid transparent;
}
/*箭头向下*/
.to_bottom {
    width: 0;
    height: 0;
    border-top: 10px solid #ccc;
    border-left: 10px solid transparent;
    border-right: 10px solid transparent;
}
/*箭头向左*/
.to_left {
    width: 0;
    height: 0;
    border-right: 10px solid #ccc;
    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
}
/*箭头向右*/
    .to_right {
    width: 0;
    height: 0;
    border-left: 10px solid #cccf;
    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
}

<div class="to_left"></div>
<p>向右箭头</p>
<div class="to_right"></div>

.text{
    display: inline-block;

    width: 100px;
    height: 100px;
