          <h6>响应式图片</h6>

          <p>在Bootstrap中，给图片添加 <code>.img-fluid</code> 样式，或定义 <code>max-width: 100%、height:auto;</code> 样式，即可赋得响应式特性，图片大小会随着父元素大小同步缩放。</p>

            <h6>IE 10问题以及SVG图形的特殊处理</h6>

            在IE 10浏览器中，带 <code>.img-responsive</code> 类的SVG图片尺寸可能会不均称，这是一个浏览器级的缺陷，你可以在相应图片元素上添加 <code>width: 100% \9</code> 来解决它（<code>width:100% \9</code> 方法不能普遍引用，否则会造成其它图片格式的混乱，所以Bootstrap没有全局自动引用之）。

          </div>

          <h6 class="mt-3">缩略图处理</h6>

          <p>除了我们的边框圆角外，您还可以使用 <code>.img-thumbnail</code> 为图像提供一个1px的圆形边框外观。</p>

          <h6 class="mt-3">图像对齐处理</h6>

          <p>对于 <code>.block</code> 属性的块状图片，我们也可以使用 浮动定义规范 或 文字对齐规范，来实现对图像的对齐、浮动控制，带 <code>.block</code> 块属性的图片，可以自动获得 <code>.mx-auto</code> 的位置对齐属性。</p>
