如何使页脚中的图像响应？

Question

我们正在为此页面使用BootStrap和JavaScript，但我们不确定如何使页脚图像响应。页面上的其他元素是响应的，但它只是页脚图像。

我已经包含了整个HTML和CSS代码。

Answer 1

您可以使用以下内容。

<img class="img-responsive" src="/path/to/image/file">

你也可以检查bootstrap

http://getbootstrap.com/css/#images

Answer 2

看起来你已经在css中设置了宽度和高度：

#footlogo {
  float: left;
  margin-left: 0px;
  height: 130px;
  width: 188px;
  margin: 1%;
  padding: 10px;
}

您是否尝试过移除此功能并应用＆＃34; img-responsive＆＃34;？

Answer 3

将尺寸（宽度和高度）添加到图像的容器中，然后添加宽度：100％;到img元素本身。
