CSS POSITIONING
INTRODUCTION
Positioning in CSS is no laughing matter for the novice or experienced designer. More often than not this can be one of these toughest stumbling blocks when learning CSS. To start things off I would like to point to an article by Noah Stokes which was published by A List Apart November 16,2010. The title of the article is called positioning 101. All participants and students becoming familiar with positing should begin by reading Noah's article before moving into the sections below.
STATIC POSITIONING *default
Just as Noah states in his article, think of static positioned elements in the documents normal flow as wooden blocks that stack upon one another.
RELATIVE POSITIONING
ABSOLUTE POSITIONING
FIXED POSITIONING
