A single value such as <code>"right"</code> will be normalized to <code>"right center"</code>, <code>"top"</code> will be normalized to <code>"center top"</code> (following CSS convention). Acceptable horizontal values: <code>"left"</code>, <code>"center"</code>, <code>"right"</code>. Acceptable vertical values: <code>"top"</code>, <code>"center"</code>, <code>"bottom"</code>. Example: <code>"left top"</code> or <code>"center center"</code>. Each dimension can also contain offsets, in pixels or percent, e.g., <code>"right+10 top-25%"</code>.

Similar to <a href="#option-my"><code>my</code></a> and <a href="#option-at"><code>at</code></a>, this accepts a single value or a pair for horizontal/vertical, e.g., <code>"flip"</code>, <code>"fit"</code>, <code>"fit flip"</code>, <code>"fit none"</code>.</p> <ul> <li> <code>"flip"</code>: Flips the element to the opposite side of the target and the collision detection is run again to see if it will fit. Whichever side allows more of the element to be visible will be used.</li> <li> <code>"fit"</code>: Shift the element away from the edge of the window.</li> <li> <code>"flipfit"</code>: First applies the flip logic, placing the element on whichever side allows more of the element to be visible.

Both <code>target</code> and <code>element</code> have these properties: <code>element</code>, <code>left</code>, <code>top</code>, <code>width</code>, <code>height</code>. In addition, there's <code>horizontal</code>, <code>vertical</code> and <code>important</code>, giving you twelve potential directions like <code>{ horizontal: "center", vertical: "left", important: "horizontal" }</code>.</p> </div> </li> <li> <div> <strong>within</strong> (default: <code>window</code>)</div> <div>Type: <a href="http://api.jquery.com/Types/#Selector">Selector</a> or <a href="http://api.jquery.com/Types/#Element">Element</a> or <a href="http://api.jquery.com/Types/#jQuery">jQuery</a> </div> <div>Element to position within, affecting collision detection.
