Sass 3.4.8 发布了,Sass 扩展了 CSS3,增加了规则、变量、混入、选择器、继承等等特性。Sass 生成良好格式化的 CSS 代码,易于组织和维护。 该版本包含两项改动: When @extending selectors inside :not(), don't add a complex selector where none existed before to avoid breaking selectors on browsers that don't support that. Add a deprecation warning for passing numbers with units to the alpha arguments to rgba() and hsla(). In a future release, a percentage will be interpreted according to the spec and other units will produce errors. 下载地址:https://github.com/sass/sass/archive/3.4.8.zip Sass 3.4.8 发布,CSS 框架下载地址
