【问题讨论】：

标签： html css ruby-on-rails ruby twitter-bootstrap

【解决方案1】：

您需要在 head 标签中添加这两行，这将解决您的响应问题

<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

最后一行用于响应目的

你还有一个 CSS 问题，你的图片太大了

在css下面应用它会处理它

.resume-itself img{
  max-width: 100%;
}

【讨论】：

对中间部分有效，但是顶部和底部都变小了，顶部的单词不再可见

【解决方案2】：

使用引导程序提供的适当类。您以错误的方式使用引导类
