CSSLint

Parsing errors should be fixed(应当修正解析错误)

 

The most important rule, as far as CSS Lint is concerned, is to ensure there are no parsing errors in the CSS. Parsing errors usually mean you mistyped a character and caused the code to become invalid CSS. These errors may cause the browser to drop a property or an entire rule. Parsing errors are always presented as errors by CSSLint, the most important issues to fix.

 

解析错误是指代码编写的错误导致的浏览器弃掉这栏规则或者是整个栏目的规则.
