CSS repeat-x但只需要图像中的一部分

Question

我使用了background-size: cover用于移动屏幕尺寸的background-size: cover 。

但是，对于台式机，如果我使用background-size: cover ，则在图像中看不到猫。 因为，我图像的原始大小是高度远大于宽度。

因此，我只想重复图像中没有出现猫的一部分。 但是，如果我使用background-size: contain ＆ background-repeat: repeat-x ，则看到的是以下内容：

（图像中的猫出现了3次。）

我想要做的是如下所示： （仅重复左右不出现猫的部分。）

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

Answer 1

并且想法是使用彼此之上的多个背景来模拟这种效果：

 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; } 

您可以根据图像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，它通过减少重复步骤来隐藏左侧不需要的部分：

在全屏上运行并与之前的代码进行比较

 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; } 

UPDATE

这是带有您的图片的代码：

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

Answer 2

也可以使用渐变来绘制不应重复图像的区域。

 html { min-height:100vh; background-image: url(https://s25.postimg.cc/kw0l49gz3/original.png), linear-gradient(to top, rgb(116, 164, 61) 27.5%, gray 27.5%, gray 27.6%, rgb(67, 97, 32) 27.6%); background-position:center center; background-repeat:no-repeat; background-size: auto 100%; } 

如果图像本身可以匹配，则可以使用图像的一部分并进行拉伸。

 html { min-height:100vh; background-image: url(https://s25.postimg.cc/kw0l49gz3/original.png), url(https://s25.postimg.cc/kw0l49gz3/original.png ); background-position:center center, 10% center ; background-repeat:no-repeat; background-size: auto 100%, 2000% 100%;/* stretch part of image behind the other one with a hudge value*/ }
