How to adjust size of the stars ?

here is what i did and allows you to freely customise the size of the stars size.

`<style>

.txt-center {
text-align: center;
}
.hide {
display: none;
}

.clear {
    float: none;
    clear: both;
}

.rating {
    width: auto;
    unicode-bidi: bidi-override;
    direction: rtl;
    text-align: left;
    position: relative;
}

    .rating > label {
        float: none;
        display: inline;
        padding: 0;
        margin: 0;
        position: relative;
        width: 1.1em;
        cursor: pointer;
        color: #000;
        font-size: 36px;  /*Right here is where you change the size*/ 
    }

        .rating > label:hover,
        .rating > label:hover ~ label,
        .rating > input.radio-btn:checked ~ label {
            color: transparent;
        }

            .rating > label:hover:before,
            .rating > label:hover ~ label:before,
            .rating > input.radio-btn:checked ~ label:before,
            .rating > input.radio-btn:checked ~ label:before {
                content: "\2605";
                position: absolute;
                left: 0;
                color: #FFD700;
            }

</style>`
