A title can be contained in different HTML tags like div, h(n) or span. A contentPage_title can accommodate different predefined CSS classes to apply wanted style (see below).
Notes : The xLarge result variant is used only on Desktop. To keep the same DOM on mobile and desktop mode, the xLarge properties are overload on mobile to match with large properties.
