Answer 1

If you want two boxes side by side then remove the br then wrap with a div and make it as flex.

Updated code :

.tile {
    background: rgb(80, 80, 80);
    width: 300px;
    height: 300px;
    border-radius: 15px;
    display: flex;
    justify-content: center;
    align-items: center;
    margin-right: auto;

}

.tile img {
    width: 50px;
}

a {
    color: #fff;
    text-decoration: none;
}

.container {
    display: flex;
}

    <div class="container">
        <a href="https://classroom.google.com/u/0/h" target="blank_">
            <div class="tile">
                <img src="icons/classes.png" alt="Classroom Image">
                <p>Google Classroom</p>
            </div>
        </a>
        <a href="https://wakeid2.wcpss.net/ui/applications" target="blank_">
            <div class="tile">
                <img src="icons/portal.png" alt="WakeID Portal Image">
                <p>WakeID Portal</p>
            </div>
        </a><br>
    </div>
