Hi, I see some example that use ionic tags withou ionic prefix that is and not .
Why this?
The difference between the two are the pure html that just use the css, or the directives that have extended the functionality.
The ion- prefixed directives, ion-list,ion-item, etc, are angular directives that let you have extended features (swipe to delete, reorder, etc).
Make sense?
Uhm…Is it possibile to add css class to ion directive?
Of course 
. Thats actually how some attributes are applied to directives.
<ion-item class="my-item-settings"></ion-item>Any docs for this tags ?
http://ionicframework.com/docs/components/ ?
css = without prefix -> only css for the styling
javascript = with prefix -> directives with additional functionality
Oh, thanks, so special html tags in javascript section, ok.
