value of field a
value of field b
-------------------------------------------------------
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah blah

so need create simple content skeleton, how?????

moving or removing author , date simple, component/com_content/content.html.php file , find there. adding more custom field not possible, you'll have hack content.html.php file careful since other contents output or display uses file too.
