Answer 1

用div直接定位放上去
例如这种

<style>
.mydiv {
    index: 9999;
    position: absolute;
    top: 100px;
    left: 100px;
    border: 1px solid blue;
    border-right: none;
    color: blue;
    height: 21px;
    width: 35px;
}
.mydiv:after {
    display: block;
    content: '';
    width: 15px;
    height: 15px;
    border: 1px solid blue;
    border-left: none;
    border-bottom: none;
    transform: rotate(45deg);
    position: absolute;
    left: 82%;
    bottom: 6%;
}
<style>
 .mydiv {
    index: 9999;
    position: absolute;
    top: 100px;
    left: 100px;
    border: 1px solid blue;
    border-right: none;
    color: blue;
    height: 21px;
    width: 35px;
}
.mydiv:after {
    display: block;
    content: '';
    width: 15px;
    height: 15px;
    border: 1px solid blue;
    border-left: none;
    border-bottom: none;
    transform: rotate(45deg);
    position: absolute;
    left: 82%;
    bottom: 6%;
}
</style>    
<div class="mydiv">99.9%</div>
