javascript - 如何在 Bootstrap 中使用 img-circle 图像在悬停时添加标题

Question

我在 bootstrap 中有一个响应式 ing-circle 链接图像网格，我希望在悬停时显示标题。

我想不出一种方法来做到这一点而不扭曲圆形图像的形状，或者让它出现在圆圈之外。

我的 CSS:

.pic{
    -webkit-filter:   saturate(50%) opacity(80% ) sepia(15%) grayscale(15%);

}

.pic img{
  -webkit-transition: all 0.5s linear;
          transition: all 0.5s linear;
  -webkit-transform: scale3d(1, 1, 1);
          transform: scale3d(1, 1, 1);
}

.pic:hover img{
-webkit-filter:  opacity(00% )brightness(120%);
  -webkit-transform: scale3d(1.2, 1.2, 1);
          transform: scale3d(1.2, 1.2, 1);
}


.circular img {
    margin: 0 auto;
    border: 6px solid  #a9c3b1;
    box-shadow: inset 0 0 0 16px rgba(255,255,255,0.6),
        0 1px 2px rgba(0,0,0,0.1);
}

img {
display: inline-block;
height: auto;
max-width: 100%;
}




#hatch {
    background-image: url("../img/hatch.png");
    opacity: 1;

}

#nakashima {
    background-image: url("../img/carat.png");
    opacity: 1;

}

#areel {
    background-image: url("../img/animation.png");
    opacity: 1;
}

我试过这方面的变体:

.figcaption {
    position: absolute;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
    border-radius: 50%;
    padding: 50% 0;
    overflow: hidden;
    color: black

    opacity: 1;

    z-index: 10
}

这是我的 HTML:

div class="row ">

                <div class="col-sm-3 col-sm-offset-1">
                    <div class="circular pic img-circle" id='hatch'>
                        <h3 class="figcaption">hatch</h3>
                        <a href="hatch.html"><img src="img/hatch.png" class="img-responsive img-circle" alt="" >
                        </a>
                    </div>
                </div>

               <div class="col-sm-3">
                    <div class="circular pic img-circle" id='nakashima'>
                        <a href="hatch.html"><img src="img/carat.png" class="img-responsive img-circle" alt="" >
                        </a>    
                        </div>
                </div>

                <div class="col-sm-3">
                    <div class="circular pic img-circle" id='areel'>
                        <a href="reel.html"><img src="img/animation.png" class="img-responsive img-circle" alt="">
                        </a>
                    </div>
                </div>

        </div>

预计到达时间:我已经为演示制作了一个 jsfiddle:https://jsfiddle.net/4btssg6y/ 比较第一个添加了文本的圆圈与第二个没有添加文本的圆圈的结果。

嗯，我想我明白了。但我很想听听是否有更好的方法来做到这一点。

HTML:
