我在 Codeacademy.com 上了一门交互式网站的类(class)并完成了它，我们建立的网站没有响应，所以我自己去学习并尝试让它成为一个响应式的网站。 我现在遇到 slider 上的图像问题，它们刚从 div 中消失，我怎样才能让它们留在那里？

最佳答案
由于您使用的是 Bootstrap ，因此您可以在图像标签中使用类 img-responsive 来使您的图像响应。
<div class="slide-img col-xs-7">
<img class="img-responsive" src="http://s3.amazonaws.com/codecademy-content/courses/ltp2/img/flipboard/home.png">
</div>
您的 HTML 将如下所示:
