Question

我希望图像能够完全显示，即使包含的元素没有填充容器，同时也能够缩放。

HTML：

<div class="row">
    <div class="col-sm-6 wrap">
        <div class="content">
            <h3>Certified</h3>
             Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
        </div>
    </div>

    <div class="col-sm-6 wrap">
        <div class="content">
            <h3>Committed Consultants</h3>
             Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

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

CSS：

.wrap {
  background: url(http://home.iiserb.ac.in/~ankurg/img/gallery/800x600.png);
  background-repeat: no-repeat;
  background-size: cover;
}

.content {}

如果要在更改容器大小时使背景图像完全可见，则需要更改为background-size: 100% 100%。显然，图像将变形以填充容器区域。我给你看一个例子：

.wrap {
  background: url(http://home.iiserb.ac.in/~ankurg/img/gallery/800x600.png);
  background-repeat: no-repeat;
  background-size: 100% 100%;
}

.content {}
