Instance Method Details

#add_protected_condition(expression, options = {}) ⇒ Object

Add a protected condition.

The contents of a protected condition will be hidden inside a comment and will not be added to the DOM by other browsers.

def add_protected_condition(expression, options = {})
  add_condition(ProtectedCondition, expression, options)
end

#add_unprotected_condition(expression, options = {}) ⇒ Object

Add an unprotected condition

The contents of an unprotected condition will NOT be hidden from other browsers. There should only be one of these configured.

This is commonly used for the modern/up-to-date/non-IE version, eg when expression is “!IE” or “gt IE 9”. Note you can add an unprotected condition using on if you use the former expression (the latter may be too optimistic!)

def add_unprotected_condition(expression, options = {})
  add_condition(UnprotectedCondition, expression, options)      
end

#on(expression, options = {}) ⇒ Object

Add a condition

Unless expression is “!IE”, this will add a “protected” condition, meaning that the contents of the condition will be hidden inside a comment and will not be added to the DOM by other browsers.

You can also use the more specific add_protected_condition and add_unprotected_condition directly.

call-seq:

on 'lt 7', :class => 'ie6'
on '!IE' # for other browsers
