About Bugfixes:

1. Fix bug that border-image test is incorrect According to CSS Backgrounds and Borders Module Level 3, border-image property's fourth value is border-image-outset property's value, not border-image-width property's value. border-image-outset property doesn't accept a percentage value.

Name: border-image Value: <‘border-image-source’> || <‘border-image-slice’> [ / <‘border-image-width’> | / <‘border-image-width’>? / <‘border-image-outset’> ]? || <‘border-image-repeat’>

Name: border-image-outset Value: [ | ]{1,4}

2. Fix bug that Media Queries's "not" keyword test is incorrect According to Media Queries, "not" keyword cannot be put in expression.

media_query_list : S* [media_query [ ',' S* media_query ]* ]? ; media_query : [ONLY | NOT]? S* media_type S* [ AND S* expression ] | expression [ AND S* expression ] ; media_type : IDENT ; expression : '(' S* media_feature S* [ ':' S* expr ]? ')' S* ; media_feature : IDENT ;

3. Fix bug that cursor test is incorrect According to CSS Basic User Interface Module Level 3, in case of image cursors, cursor property is two-value syntax, not one-value syntax.

Name: cursor Value: [ [ [ ]?,]* [ auto | default | none | context-menu | help | pointer | progress | wait | cell | crosshair | text | vertical-text | alias | copy | move | no-drop | not-allowed | e-resize | n-resize | ne-resize | nw-resize | s-resize | se-resize | sw-resize | w-resize | ew-resize | ns-resize | nesw-resize | nwse-resize | col-resize | row-resize | all-scroll | zoom-in | zoom-out ] ] | inherit

4. Remove border-width from properties of Values and Units According to CSS Backgrounds and Borders Module Level 3 and CSS Values and Units Module Level 3, border-width property doesn't accept a value containing the percentage, like "calc(100%/3 - 2_1em - 2_1px)".

= | thin | medium | thick

http://www.w3.org/TR/css3-background/#ltborder-widthgt

If percentages are accepted in the context in which the expression is placed, a PERCENTAGE token has the type of the value that percentages are relative to; otherwise, a math expression containing percentages is invalid.
