Question

我试图修改Bootstrap的主题名为＆＃39; Agency＆＃39;。我遇到的具体问题是，当屏幕缩小时，我希望圆形徽标（右上角）响应和缩小。我已经尝试将img-responsive类标记添加到图像中，但这并不起作用。我想知道以前的班级是否覆盖了img-responsive类？

这是导航部分的html ...

Answer 1

图像宽度和高度不够大，因此随着屏幕缩小，图像不会适应。作为测试，尝试使图像大小更大并添加引导程序class="img-responsive"类，您将看到它的工作原理。

你可以做的是在特定的断点处为图像元素添加100％的高度，因为它适合其父级，即50px的navbar-brand，然后相应地覆盖填充。然后在桌面断点处取下此100％高度并将其设置为auto以包含该元素。

希望这是有道理的。

Answer 2

尝试这样做

img {
max-width: 100%;
height: auto;
width: auto\9; /* ie8 */
}
