CSS 中的 if条件语句
from Web技术动态
该博客文章来自 Chrome for Developers，重点介绍了从 Chrome 137 开始推出的 CSS if() 函数。此函数引入了一种更简洁的方式来创建 CSS 内联条件语句，支持 style()、media() 和 supports() 查询。文章通过 内联媒体查询（用于根据指针类型调整按钮大小）、内联支持查询（用于检查颜色空间支持）和可视化 UI 状态（基于数据属性设置元素样式）等示例，展示了 if() 函数的实际应用。该功能旨在为开发人员提供新的 CSS 架构机会，允许更灵活、更直接地进行样式控制，而无需依赖父元素进行查询。
