CSS 文字描边效果全解
什么是文字描边?
CSS 文字描边(Text Stroke)是一种现代网页设计技术,它允许开发者为文本字符添加轮廓或边框效果。这种技术通过为文字创建可见的边界线,显著增强文本的视觉冲击力和可读性,特别是在复杂背景或图像上显示文字时特别有用。
文字描边效果由两个主要属性控制:
-
text-stroke-width:定义描边的粗细程度 -
text-stroke-color:定义描边的颜色
基本语法与浏览器兼容性
.selector {
-webkit-text-stroke: <width> <color>; /* WebKit 浏览器前缀 */
text-stroke: <width> <color>; /* 标准语法 */
}
由于文字描边仍处于标准化过程中,建议同时使用标准属性和浏览器前缀属性确保跨浏览器兼容性。
