Content width question

Hi
There is one thing that confuses me. How does the Content Width override works in Template layouts. If I for example would like all other pages except the front page main body wider, how can I do that?
Another thing, in the Fashion template sample data there is a content widths override on itemid 101 and 127, what do they refer to? I can’t for example don’t find id 127 anywhere.
And what is an "option"?
(I am a bit of a newbie on Gavick and K2 but have been using Joomla for a long time)

Hi

To make a different widths for elements in some pages only you can use a direct menuitem Id and point the exact change. To be honest I prefer more old school way to use a mod blank with overrides of CSS and attached to desired pages only.
