Is this good practice?

Question

Layout

Am I doing the right thing?
According to the layout corresponds

.title h2 {
margin-bottom: 17px;
position: relative;
}

.title h2::after {
    content: '';
    position: absolute;
    background-image: url(../img/Vector.svg);
    background-repeat: no-repeat;
    top: -25px;
    margin-left: -8px;
    width: 48px;
    height: 48px;
    }

<div class="title center">
            <h2>Надёжность</h2>
        </div>
