This is placed immediately in front of the?feature, ?operator, or?subexpression?to reverse the Boolean meaning of the expression._ **NOT运算符。这是摆立即在前面的_功能_，_操作员_，或_子表达式_扭转布尔表达式的意义。** lt \[if lt IE 5.5\] _The less-than operator. Returns true if the first argument is less than the second argument._ **小于运算符。如果第一个参数小于第二个参数，则返回true。** lte \[if lte IE 6\] _The less-than or equal operator. Returns true if the first argument is less than or equal to the second argument._ **小于或等于运算。如果第一个参数是小于或等于第二个参数，则返回true。** gt \[if gt IE 5\] _The greater-than operator. Returns true if the first argument is greater than the second argument._ **大于运算符。如果第一个参数大于第二个参数，则返回true。** gte \[if gte IE 7\] _The greater-than or equal operator. Returns true if the first argument is greater than or equal to the second argument._ **大于或等于运算。如果第一个参数是大于或等于第二个参数，则返回true。** ( ) \[if !(IE 7)\] _Subexpression operators. Used in conjunction with boolean operators to create more complex expressions._ **子表达式运营商。在与布尔运算符用于创建更复杂的表达式。** & \[if (gt IE 5)&(lt IE 7)\] _The AND operator. Returns true if all subexpressions evaluate to true_ **AND运算符。如果所有的子表达式计算结果为true，返回true** \[if (IE 6)(IE 7)\] _The OR operator. Returns true if any of the subexpressions evaluates to true._ **OR运算符。返回true，如果子表达式计算结果为true。**   举个栗子 ``` ```
