    height: 3em;
    width: 3em;
    display: inline-block;
}

                <div class="img"></div>
                instagram
            </div>
            <div class="sm">
                <div class="img"></div>
                facebook
            </div>
            <div class="sm">

                isntagram
            </div>

Answer 1

Add vertical-align:middle; to img or div .

.img {
    background-color: red;
    height: 3em;
    width: 3em;
    display: inline-block;
    vertical-align: middle; /*CAN GO HERE*/
}

div {
    vertical-align: middle; /*OR HERE*/
}

You should add a margin to the elements after to ensure that they're not all stuck together.
