今天我们要介绍100多个使用单个元素制作的CSS丝带。是的，只用到一个元素。

这可不是用旧的和过时的代码制作的CSS丝带，而是用现代CSS制作的，并对CSS变量进行了优化。没有幻数也没有固定尺寸。随你所愿可以将所有丝带放置于任何内容之中，通过调整变量即可轻松控制。

只需单击一下即可复制丝带的CSS代码，无论是经典的丝带，还是新式的、花哨的，总有一款让你眼前一亮。

你还在等什么？一起来看看吧。

多行丝带

当当当当，我可是我的最爱。创建适合多行文本的丝带是有挑战性的，但也难不倒我。

编辑文本我们可以看到丝带将自动调整以适应内容。

弯曲的丝带

将直线文本与弯曲的丝带结合起来并不容易，但成品效果也很有意思。

无限丝带

一直延伸的丝带？让我试着制作看看！这样的丝带可以向某个方向（顶部、底部、右侧、左侧）延伸直到屏幕的边缘。

因为是在没有伪元素的情况下构建的，所以不会产生任何溢出问题。请看下面的两个演示：
