你如何防止在 CSS 中调整图像大小? [英] How do you prevent resizing of images in CSS?

问题描述

我有以下代码来创建图像库.他们需要做出回应.但问题是，当窗口宽度发生变化时，图像也会调整大小并失去纵横比.

I have the following code to create a gallery of images. They need to be responsive. But the problem is, when the window width changes, the images also get resized and lose their aspect ratios.

我该如何解决这个问题?我是 CSS 新手.

How can I fix this? I am new to CSS.

推荐答案

img {
    max-width: 100%;
    height: auto;
    width: auto9; /* ie8 */
}

然后您只需使用 img 标签添加的任何图像都将是灵活的

and then any images you add simply using the img tag will be flexible

要使图像灵活，只需添加 ma​​x-width:100% 和 height:auto.图片 max-width:100% 和 height:auto 在 IE7 中有效，但在 IE8 中无效(是的，另一个奇怪的 IE 错误).要解决此问题，您需要为 IE8 添加 width:auto9.

To make the images flexible, simply add max-width:100% and height:auto. Image max-width:100% and height:auto works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to add width:auto9 for IE8.
