我正在寻找一种脚本，使用CSS创建玻璃破碎效果，但没有找到任何内容。如何使用文本获得玻璃破碎效果
我用这个，但

转换代码块到一个片断，因为它更容易比CSS的整个大的代码块读+ JS + HTML。你的问题描述是不完整的，但是由于这个代码片段没有像在连接笔中那样执行，我认为你是在问为什么它没有在整体上工作。如果这确实是个问题，那么请查看该笔中链接的External JS文件（单击JS选项卡标题中的齿轮图标）。 – Harry
我们可以用CSS或javascript制作玻璃破碎效果我想用玻璃破碎做出带有文字的商标我的页眉颜色为浅蓝色，应该匹配 – deb
您必须先尝试。如果您遇到任何困难，请寻求帮助，并指出您需要帮助的问题到底是什么。如果你正在寻找人来编写整个事情，那么恐怕这个问题太广泛了。 – Harry
