Im trying to create star rating based on score or percentage. I have created codepen for inline stars. But don’t understand how to do for stars shown in image. Stars should not be inline, they should formed a triangle.
Will you please help me with that.

and my codepen link

/*---------- general ----------*/
body {
    background: #ff7070;
    color: #F3FCF0;
    font-family: sans-serif;
    text-align: center;
}

/*---------- star rating ----------*/
%flex-display {
    display: flex;
}
.star-rating {
    @extend %flex-display;
    align-items: center;
    font-size: 3em;
    justify-content: center;
    margin-top: 50px;
}
.back-stars {
    @extend %flex-display;
    color: #bb5252;
    position: relative;
    text-shadow: 4px 4px 10px #843a3a;
}
.front-stars {
    @extend %flex-display;
    color: #FFBC0B;
    overflow: hidden;
    position: absolute;
    text-shadow: 2px 2px 5px #d29b09;
    top: 0;
}
<script src="https://use.fontawesome.com/f4e64b7c17.js"></script>
<div class="star-rating">
    <div class="back-stars">
        <i class="fa fa-star" aria-hidden="true"></i>
        <i class="fa fa-star" aria-hidden="true"></i>
        <i class="fa fa-star" aria-hidden="true"></i>>
        
        <div class="front-stars" style="width: 70%">
            <i class="fa fa-star" aria-hidden="true"></i>
            <i class="fa fa-star" aria-hidden="true"></i>
            <i class="fa fa-star" aria-hidden="true"></i>

        </div>
