尝试使网站响应时出现图像问题

Question

我参加了 Codeacademy.com 的交互式网站课程并完成了它，我们建立的网站没有响应，所以我自己去学习并尝试使它成为一个响应式的网站。我现在遇到滑块上的图像问题，它们刚从 div 中消失，我怎样才能让它们留在那儿？

Answer 1

让任何图片自动响应

img {
    max-width: 100%;
    display: block;
    height: auto;
}

现在图像将根据其父宽度显示。

谢谢

Answer 2

作为您使用 bootstrap，您可以使用 class ".img-responsive"，例如：

<img class="img-responsive" src="http://s3.amazonaws.com/codecademy-content/courses/ltp2/img/flipboard/logo.png">

Answer 3

由于您使用的是 bootstrap，因此您可以在图片标签中使用 class img-responsive 使您的图片响应。

<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>
