<p>Calculates and sets the alignment of the element <code>element</code>.</p>
<h4 id="verticaloffset-number"><code>verticalOffset: number</code><a class="headerlink" href="#verticaloffset-number" title="Permanent link">#</a></h4>
<p><em>Defaults to <code>0</code>.</em></p>
<p>Creates a gap between the element and the reference element, in pixels.</p>
<h4 id="pointer-boolean"><code>pointer: boolean</code><a class="headerlink" href="#pointer-boolean" title="Permanent link">#</a></h4>
<p><em>Defaults to <code>false</code>.</em></p>
<p>Sets the position of the pointer element, requires an existing child of the
element with the CSS class <code>.elementPointer</code>.</p>
<h4 id="pointeroffset-number"><code>pointerOffset: number</code><a class="headerlink" href="#pointeroffset-number" title="Permanent link">#</a></h4>
<p><em>Defaults to <code>4</code>.</em></p>
<p>The margin from the left/right edge of the element and is used to avoid the
arrow from being placed right at the edge.</p>
<p>Does not apply when aligning the element to the reference elemnent's center.</p>
<h4 id="pointerclassnames-string"><code>pointerClassNames: string[]</code><a class="headerlink" href="#pointerclassnames-string" title="Permanent link">#</a></h4>
<p><em>Defaults to <code>[]</code>.</em></p>
<p>If your element uses CSS-only pointers, such as using the <code>::before</code> or <code>::after</code>
pseudo selectors, you can specifiy two separate CSS class names that control the
alignment:</p>
<ul>
<li><code>pointerClassNames[0]</code> is applied to the element when the pointer is displayed
   at the bottom.</li>
<li><code>pointerClassNames[1]</code> is used to align the pointer to the right side of the
  element.</li>
</ul>
<h4 id="refdimensionselement-element"><code>refDimensionsElement: Element</code><a class="headerlink" href="#refdimensionselement-element" title="Permanent link">#</a></h4>
<p><em>Defaults to <code>null</code>.</em></p>
<p>An alternative element that will be used to determine the position and dimensions
of the reference element. This can be useful if you reference element is contained
in a wrapper element with alternating dimensions.</p>

<p><em>Defaults to <code>"left"</code>.</em></p>
<p>Sets the prefered alignment, accepts either <code>left</code> or <code>right</code>. The value <code>left</code>
instructs the module to align the element with the left boundary of the reference
element.</p>
<p>The <code>horizontal</code> alignment is used as the default and a flip only occurs, if there
is not enough space in the desired direction. If the element exceeds the boundaries
in both directions, the value of <code>horizontal</code> is used.</p>
<h4 id="vertical-string"><code>vertical: string</code><a class="headerlink" href="#vertical-string" title="Permanent link">#</a></h4>
<p><em>Defaults to <code>"bottom"</code>.</em></p>
<p>Sets the prefered alignment, accepts either <code>bottom</code> or <code>top</code>. The value <code>bottom</code>
instructs the module to align the element below the reference element.</p>
<p>The <code>vertical</code> alignment is used as the default and a flip only occurs, if there
is not enough space in the desired direction. If the element exceeds the boundaries
in both directions, the value of <code>vertical</code> is used.</p>
<h4 id="allowflip-string"><code>allowFlip: string</code><a class="headerlink" href="#allowflip-string" title="Permanent link">#</a></h4>

<p><em>Defaults to <code>"both"</code>.</em></p>
<p>Restricts the automatic alignment flipping if the element exceeds the window
boundaries in the instructed direction.</p>
<ul>
<li><code>both</code> - No restrictions.</li>
<li><code>horizontal</code> - Element can be aligned with the left <em>or</em> the right boundary of

<li><code>vertical</code> - Element can be aligned below <em>or</em> above the reference element,
