边框图像路径 | border-image-source (Backgrounds & Borders) - CSS 中文开发手册
border-image-sourceCSS属性定义<image>,而不是使用边框的风格。如果此属性设置为none,border-style则使用由其定义的样式。
/* no border-image, use the specified border-style */ border-image-source: none; /* the image.jpg is used as image */ border-image-source: url(image.jpg); /* a gradient is used as image */ border-image-source: linear-gradient(to top, red, yellow); /* Global values */ border-image-source: inherit; border-image-source: initial; border-image-source: unset;
注意:虽然<image>CSS属性可以使用任何CSS,但浏览器支持仍然有限,某些浏览器仅支持使用url()功能符号定义的图像。
