Answer 3

或者，您可以使用box-shadow代替border：

＆＃13;

＆＃13;

.icon {
    text-align: center;
    position: relative;
}

.info {
    margin-top: -24px;
    background: hsla(0, 0%, 0%, 0.04);
    border: 1px solid hsl(0, 0%, 88%);
    padding: 15px 0 10px 0;
}

.image {
    position: relative;
    z-index: 2;
    margin: auto;
    width: 76px;
    height: 76px;
    /* border: 7px solid hsl(0, 100%, 100%); */
    line-height: 76px;
    border-radius: 50%;
    background: hsl(126, 37%, 55%);
    vertical-align: middle;
    -webkit-box-shadow: 0 0 0 7px white;
    -moz-box-shadow: 0 0 0 7px white;
    box-shadow: 0 0 0 7px white;
}

.icon:hover .image {
    -webkit-box-shadow: 0 0 0 7px black;
    -moz-box-shadow: 0 0 0 7px black;
    box-shadow: 0 0 0 7px black;
}

.image .glyphicon {
    font-size: 38px;
    line-height: 1.33;
    color: white;
}

＆＃13;

        <div class="info">
            <h3 class="title">Messages</h3>
            <p>
                7 new messages over the past 24 hours. 
            </p>
            <div class="more">
                <a href="#" title="Title Link"><i class="fa fa-plus"></i> Details
