尝试使网站响应时出现图像问题答案

【问题标题】：Problems with images when trying to make a website responsive尝试使网站响应时出现图像问题
【发布时间】：2016-04-08 17:07:07
【问题描述】：

我在 Codeacademy.com 上了一门交互式网站课程并完成了它，我们建立的网站没有响应，所以我自己去学习它并尝试使其成为响应式网站。我现在对滑块上的图像有问题，它们只是从 div 中消失，我怎样才能让它们留在那里？

【问题讨论】：

你好，显示代码 sn-ps 的最佳方式是使用 jsfiddle.net/ 或 codepen.io 之类的东西，或者您甚至可以使用堆栈溢出自己的代码插入工具。
好的，非常感谢
img { 最大宽度：100% }
不行，已经试过了

标签： html css responsive-design web responsive

【解决方案1】：

由于您使用的是引导程序，因此您可以在图像标签中使用类 img-responsive 来使您的图像具有响应性。

<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：

【解决方案2】：

让任何图像自动响应

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

现在图像将根据其父宽度显示。

谢谢

【讨论】：

你好，图片还在div之外。

【解决方案3】：

作为您使用的引导程序，您可以使用“.img-responsive”类，例如：

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

【讨论】：

仍然图像超出边界，在我们在课程中制作的代码中，我们为 img 链接上的图像添加了宽度，如下所示：s3.amazonaws.com/codecademy-content/courses/ltp2/img/flipboard/…" width="540px" >
我不明白 .. 你在说哪个滑块？滑块在您的小提琴上不起作用。
它不起作用，因为图片正在禁用它，因为它超出了 div
