我刚刚开始学习前端网络开发。我正在制作我的投资组合模型，但我在调整图像大小方面遇到了问题。我正在使用 Bootstrap 框架。当我使用具有 img-responsive 类的图像时，我上传的图像的高度和宽度会自动设置。由于我想自己设置高度，所以我更改了图像的高度(在 css 文件中)。但是，现在当我减小浏览器的宽度以查看我的投资组合在移动 View 中的外观时，宽度会调整大小但高度保持不变。这使图像看起来不成比例。我怎样才能解决这个问题？如果我不使用自定义高度，则在移动 View 中一切正常。
最佳答案
这在我的谷歌浏览器中对我有用。至于移动 View 和其他设备，此元标记有助于“meta name="viewport"content="width=device-width, initial-scale=1.0"(请参阅我的 html head 元素中的元标记)
