html - 如何根据媒体查询更改图像大小？

Question

我正在尝试在此链接中实现此组合:

http://www.htmldrive.net/items/demo_show/1258

我在我的 mvc5 元素中下载并实现了它，它工作正常，但是我在这个组合中使用的 css 和媒体查询有一些问题。我想在缩小图像时对图像大小和列数进行一些更改浏览器。在这个作品集中，所有图像都应该是 144x144px 4 列，但我不想要它。我想要更大的图像，我也希望它像 bootstrap 网格系统一样工作，但是当我缩小浏览器列时更改为 1 列。任何人都可以帮助我吗？ 我对媒体查询一无所知。

Answer 1

您可以在带有较大图像的示例中使用相同的代码和样式。

删除或更改以下样式规则中的宽度。

.freshdesignweb {
  margin: 0 auto;
  width: 650px;
}
.image_grid {
  float: left;
  overflow: hidden;
  width: 700px;
  position: relative;
}
