CSS repeat-x 但只是图像中我想要的部分

Question

我使用 background-size: cover 作为移动屏幕尺寸。

但是，对于桌面，如果我使用 background-size: cover ，我在图像中看不到猫。因为，我的图像的原始大小是高度比宽度长得多。

所以，我想只重复图像中没有出现猫的部分。但是，如果我使用 background-size: contain & background-repeat: repeat-x，我会看到以下内容:

(图中的猫出现了3次。)

我想做的是类似下面的事情: (只重复左右两边猫没有出现的部分。)

我在谷歌上搜索了很多，并阅读了 StackOverflow 中的几篇文章。但是，我找不到我想要的答案。如果您能给我任何建议，我将不胜感激!

Answer 1

想法是使用多个背景叠加在一起来模拟这样的效果:

body {
 margin:0;
 min-height:500px;
 height:100vh;
 background:
   /*the main background*/
   url(https://picsum.photos/3744/5616?image=742) center,
   /*repeat the left part*/
   url(https://picsum.photos/3744/5616?image=742) 40% 50%,
   url(https://picsum.photos/3744/5616?image=742) 30% 50%,
   url(https://picsum.photos/3744/5616?image=742) 20% 50%,
   url(https://picsum.photos/3744/5616?image=742) 10% 50%,
   url(https://picsum.photos/3744/5616?image=742) 0% 50%,
   /*repeat the right part*/
   url(https://picsum.photos/3744/5616?image=742) 60% 50%,
   url(https://picsum.photos/3744/5616?image=742) 70% 50%,
   url(https://picsum.photos/3744/5616?image=742) 80% 50%,
   url(https://picsum.photos/3744/5616?image=742) 90% 50%,
   url(https://picsum.photos/3744/5616?image=742) 100% 50%;
  background-repeat:no-repeat;
  background-size:contain;
}

根据图像，您可以调整背景的百分比和数量以控制重复。这是对第一个代码的改进，通过减少重复的步骤来隐藏左侧不需要的部分:

全屏运行并比较这段代码和之前的代码

body {
 margin:0;
 min-height:500px;
 height:100vh;
 background:
   /*the main background*/
   url(https://picsum.photos/3744/5616?image=742) center,
   /*repeat the left part more than the right*/
   url(https://picsum.photos/3744/5616?image=742) 45% 50%,
   url(https://picsum.photos/3744/5616?image=742) 40% 50%,
   url(https://picsum.photos/3744/5616?image=742) 35% 50%,
   url(https://picsum.photos/3744/5616?image=742) 30% 50%,
   url(https://picsum.photos/3744/5616?image=742) 25% 50%,
   url(https://picsum.photos/3744/5616?image=742) 20% 50%,
   url(https://picsum.photos/3744/5616?image=742) 15% 50%,
   url(https://picsum.photos/3744/5616?image=742) 10% 50%,
   url(https://picsum.photos/3744/5616?image=742) 5% 50%,
   url(https://picsum.photos/3744/5616?image=742) 0% 50%,
   /*repeat the right part*/
   url(https://picsum.photos/3744/5616?image=742) 60% 50%,
   url(https://picsum.photos/3744/5616?image=742) 70% 50%,
   url(https://picsum.photos/3744/5616?image=742) 80% 50%,
   url(https://picsum.photos/3744/5616?image=742) 90% 50%,
   url(https://picsum.photos/3744/5616?image=742) 100% 50%;
  background-repeat:no-repeat;
  background-size:contain;
}

更新

这是带有您的图片的代码:

body {
 margin:0;
 min-height:500px;
 height:100vh;
 background:
   /*the main background*/
   url(/image/76q2w.png) center,
   /*repeat the left part*/
   url(/image/76q2w.png) 40% 50%,
   url(/image/76q2w.png) 30% 50%,
   url(/image/76q2w.png) 20% 50%,
   url(/image/76q2w.png) 10% 50%,
   url(/image/76q2w.png) 0% 50%,
   /*repeat the right part*/
   url(/image/76q2w.png) 60% 50%,
   url(/image/76q2w.png) 70% 50%,
   url(/image/76q2w.png) 80% 50%,
   url(/image/76q2w.png) 90% 50%,
   url(/image/76q2w.png) 100% 50%;
  background-repeat:no-repeat;
  background-size:contain;
}
