This paragraph should be green, because only the rotation should be ignored.

This paragraph should be green, since error-checking should be done before calculating specificity.

This paragraph should have a solid gray background (or a white grid), because in CSS1, inherit is an invalid keyword, and in CSS2, it will cause the gray background (not the white grid) to be inherited.

This paragraph should be black, since in CSS1, the selector is invalid, and in CSS2, it does not apply.

This paragraph should be black, since in CSS1, the selector is invalid, and in CSS2, it does not apply.

This paragraph should have a white background, since keywords cannot be quoted.

This paragraph should have a medium-width border around it (the same as the next three paragraphs). This should cause the user agent to use the default value of 'medium'.

This paragraph should have a medium-width border around it (the same as the previous and the next two paragraphs), because the border-width is invalid. This should cause the user agent to use the default value of 'medium'.

This paragraph should have a medium-width border around it (the same as the next and the previous two paragraphs), because the border-width units are invalid, and therefore the border-width should be ignored. This should cause the user agent to use the default value of 'medium'.

This paragraph should have a medium-width border around it (the same as the previous three paragraphs), because the border-width does not have any value to go with its pixel unit, and is therefore invalid. This should cause the user agent to use the default value of 'medium'.

This paragraph should be black, because the style declaration that applies to it is within an invalid at-rule.

This paragraph should be green. CSS is case-insensitive, unless required to be case sensitive due to interaction with other standards (e.g., font names or URLs.)

1. This ordered list item should be black, because the declaration has an invalid pseudo-class selector.

This paragraph should be black, because, in CSS1, :first-child is an invalid pseudo-class, and in CSS2, this paragraph is not the first child.

• This unordered list item should be black, because, according to CSS1, the selector is invalid, and according to CSS2, the selector should not apply.

This blockquote should be black, because, according to CSS1, the selector is invalid, and according to CSS2, the selector should not apply.

This paragraph should be black, because the style declaration that applies to it is within an invalid at-rule.

The text of this paragraph should be normal (that is, it should not be underlined, overlined, stricken, or bold), because diagonal is not a valid keyword, making the text-decoration invalid. In addition, highlighted is not a valid part of the font property, making it invalid. Therefore, this paragraph's font should be the UA default, and match the next paragraph. If this is not the case, then the font declaration is being improperly parsed.

In addition, highlighted is not a valid part of the font property, making it invalid. Therefore, this paragraph's font should be the UA default, and match the previous paragraph. If this is not the case, then the font declaration is being improperly parsed.

The text of this paragraph should be normal size because the selector is invalid. The emphasized text and the strong text within it should also be normal size, since the entire ruleset should be skipped (since in some future version of CSS, there could be an operator within the selector that has higher precedence than a comma).

This paragraph should be black, because the line before the declaration is not a comment and therefore the selector for P.nineteenb is invalid.

This paragraph should be blue, because only the first declaration is invalid.

This paragraph should be green, because only the first declaration is invalid.

This paragraph should be purple, because only the first declaration is invalid.

This paragraph should be green, because only the first declaration is invalid.
