如何使手机（360X640px）和iPad（768X1024px）的图像响应？你能告诉我CSS代码吗？

我必须在移动设备中提供两个图像，在iPad中提供四个图像！

Answer 1

以下是您需要遵循的代码：

img {
    max-width: 100%;
    height: auto;
    }

参考：http://html5hub.com/html5-picture-element/

Answer 2

从width代码中移除height和img属性，并为此图片添加CSS文件max-width:100%; width:100%;

Answer 3

将您要设置的图像设置为div中的背景图像，并将背景大小设置为封面

background-image: url('YOUR URL');
background-size: cover;

Answer 4

以百分比设置宽度和高度

  <img class="img1" width="100%" height="100%"/>

使用媒体查询

/ *风景* /

@media screen and (min-aspect-ratio: 1/1) {

 //use your style for landscape
                                          }

/ * Portrait（即窄视口）* /

@media screen and (max-aspect-ratio: 1/1) {

// your style for portrait
                                          }

Answer 5

使用媒体查询，您可以根据需要分割图像。

.abc{padding:0; margin:0; box-sizing:border-box; width:100%;}
.bcd{display:inline-block;width:24%;}
@media all and (max-width: 360px){
   .bcd
   {
    display:inline-block;
    width:49%;
   }
}

Answer 7

    <style>
    @media only screen and (max-width: 1024px) {    
        .abc .bcd{max-width:100%;height:auto;border:1px solid #ff0000;width:24%;display:inline-block;}
        .abc .bcd a img{width:100%;height:auto;}
    }

    @media only screen and (max-width: 640px) { 
        .abc .bcd{max-width:100%;height:auto;border:1px solid #ff0000;width:48%;display:inline-block;}
        .abc .bcd a img{width:100%;height:auto;}
    }
    </style>

您可以删除边框。

如果删除边框，则可以在一行中使用4％的宽度，在一行中使用50％的2行。
