Question

我为我的画廊制作了悬停效果。该画廊位于Bootstrap网格内。悬停本身工作正常，但在某些屏幕尺寸中，叠加层会覆盖图库图像。

有没有人有这个问题的想法，解决方案或暗示？

这是一个例子：

HTML：

    <div class="container">
        <div class="row">

            <div class="col-md-4 col-sm-4">
                <a href="http://www.google.com">
                    <div class="box">
                        <img class="img-responsive" src="http://placehold.it/300x300" />
                        <div class="overbox">
                            <div class="title overtext">Client</div>
                            <div class="tagline overtext">Tag</div>
                        </div>
                    </div>
                </a>
            </div>

            <div class="col-md-4 col-sm-4">
                <a href="http://www.google.com">
                    <div class="box">
                        <img class="img-responsive" src="http://placehold.it/300x300" />
                        <div class="overbox">
                            <div class="title overtext">Client</div>
                            <div class="tagline overtext">Tag</div>
                        </div>
                    </div>
                </a>
            </div>

            <div class="col-md-4 col-sm-4">
                <a href="http://www.google.com">
                    <div class="box">
                        <img class="img-responsive" src="http://placehold.it/300x300" />
                        <div class="overbox">
                            <div class="title overtext">Client</div>
                            <div class="tagline overtext">Tag</div>
                        </div>
                    </div>
                </a>
            </div>

        </div>
    </div>

CSS：

.box {
    position: relative;
    cursor: pointer;
    width: 100%;
    min-height: 100%;
    overflow: hidden;
    margin-bottom: 30px;
}

.box .overbox {
    position: absolute;
    width: 100%;
    height: 100%;

    left: 0;
    z-index: 100;

.box .title {

    -moz-filter: grayscale(0%);

.img-responsive {
    margin: 0 auto;
}

Answer 1

叠加层覆盖图库图像，因为叠加层已width:100%;，当图像小于其容器宽度时，由于图像宽度，叠加层会覆盖图库图像

您有2个选项可以制作图片width:100%，或者您可以更改.box类的样式并移除width:100%;并制作其display:inline-block;

.box {
    position: relative;
    cursor: pointer;
    // width: 100%;          // remove this
    display:inline-block;    // add this
    min-height: 100%;
    overflow: hidden;
    margin-bottom: 30px;
}

Answer 2

当图像具有相同的固定大小时，Bootstrap列正在增长和缩小。因此.responsive-image小于其父div。有几个解决方案：

1）删除html中的图像并将其作为背景图像

.box {
   background: url(image-url) cover no-repeat;
}

2）使图像100％宽度

.response-image {
    width: 100%;
}

3）或正如Ahmed Salama建议的那样，删除width: 100%并添加display: inline-block;

Answer 3

您的占位符小于父div元素，该元素适合其父元素的整个元素。这是由类img响应引起的，它本身适合图像到＆＃34; max-width：100％＆＃34;。您应该使用更大的图像或使其适合您父盒的大小，不建议使用。

在这支笔中，我将占位符更改为767px x 767px：http://codepen.io/pure180/details/OXpNxM/ HTML：

            <div class="col-md-4 col-sm-4">
                <a href="http://www.google.com">
                    <div class="box">
                        <img class="img-responsive" src="http://placehold.it/767x767" />
                        <div class="overbox">
                            <div class="title overtext">Client</div>
                            <div class="tagline overtext">Tag</div>

                </a>
            </div>

            <div class="col-md-4 col-sm-4">

                        <div class="overbox">
                            <div class="title overtext">Client</div>

                    </div>
                </a>
            </div>

  height: 100%;
  left: 0;
  opacity: 0;
  position: absolute;
  top: 0;
  -webkit-transition: all 300ms ease-out;
  -moz-transition: all 300ms ease-out;
  -o-transition: all 300ms ease-out;
  -ms-transition: all 300ms ease-out;
  transition: all 300ms ease-out;
  width: 100%;
