      <h2>How It Works</h2>
      <p>
        The footer is comprised of two layers, the filter control layer and the
        avatar layer. The filter layer sits on top of the avatar layer, both of
        them absolutely positioned within the footer, which is fixed to the
        bottom of the screen.
      </p>
      <p>
        Both layers are flex containers that take up the entire width of the footer.
      </p>

      <h3>Filter Layer</h3>
      <p>
        The filter layer is comprised of three divs, one for the type filter,
        one for the search filter, and one to fill the space in between. The
        left and right divs use default flex rules, the center one uses
        <code>flex:1</code> to force it to fill.
      </p>

      <h3>Avatar Layer</h3>
      <p>
        The avatar layer is comprised of three divs. The center one has a hard
        width of 45px. The left and right columns share the remaining space
        equally.
      </p>
      <p>
        On initialization, avatars are moved from the center into the left and
        right column, alternating. By setting the proper margin (left margin
        for right column, right margin for left column) you can control the
        spacing of each avatar uniformally.
      </p>

      <h3>Punching Through The Filter</h3>
      <p>
        Because we want the avatars to be vertically centered according to the
        entire page, not to it's bounding box, I elected to put them on two
        different layers. The problem then is that the center column for the
        filter control layer covers the avatar layer, and so pointer events
        aren't registered.
      </p>
      <p>
        To fix this, the filter control layer has the CSS property
        <code>pointer-events: none</code>, which prevent it from receiving any
        mouse or touch events (hover, click, everything). Then, because we *do*
        want to support pointer events on the left and right columns (where the
        controls are), we manually reenable pointer-events for those
        (<code>pointer-events: all</code>).
      </p>
      <p>
        Combine the pointer-event disable with setting the opacity of the
        center filter column to 0 and it appears that you are interacting
        directly with the underlying layer (the avatar layer); effectively
        punching a hole through the dead space on the top layer to the one
        underneath.
      </p>

      <div id="instructions">
        <h2>Instructions</h2>
        <p>
          Click an avatar to expand, click it again after expanding to select.
          You can use the buttons below as well. Hover the two controls on the
          left and right to watch them expand without the avatars moving at
          all. Resize the screen and watch as the avatars stay perfectly
          centered.
        </p>
        <p>
          <strong>Reset</strong> will stack all of the avatars on top of one
          another. <strong>Expand</strong> will show the full expansion where
          each avatar has breathing room. <strong>Collapse</strong> will put the
          avatars back into the fan-out stack, which is the default
          representation.
        </p>

	<h2>How It Works</h2>
	<p>
	The footer is comprised of two layers, the filter control layer and the
	avatar layer. The filter layer sits on top of the avatar layer, both of
	them absolutely positioned within the footer, which is fixed to the
	bottom of the screen.
	</p>
	<p>
	Both layers are flex containers that take up the entire width of the footer.
	</p>

	<h3>Filter Layer</h3>
	<p>
	The filter layer is comprised of three divs, one for the type filter,
	one for the search filter, and one to fill the space in between. The
	left and right divs use default flex rules, the center one uses
	<code>flex:1</code> to force it to fill.
	</p>

	<h3>Avatar Layer</h3>
	<p>
	The avatar layer is comprised of three divs. The center one has a hard
	width of 45px. The left and right columns share the remaining space
	equally.
	</p>
	<p>
	On initialization, avatars are moved from the center into the left and
	right column, alternating. By setting the proper margin (left margin
	for right column, right margin for left column) you can control the
	spacing of each avatar uniformally.
	</p>

	<h3>Punching Through The Filter</h3>
	<p>
	Because we want the avatars to be vertically centered according to the
	entire page, not to it's bounding box, I elected to put them on two
	different layers. The problem then is that the center column for the
	filter control layer covers the avatar layer, and so pointer events
	aren't registered.
	</p>
	<p>
	To fix this, the filter control layer has the CSS property
	<code>pointer-events: none</code>, which prevent it from receiving any
	mouse or touch events (hover, click, everything). Then, because we do
	want to support pointer events on the left and right columns (where the
	controls are), we manually reenable pointer-events for those
	(<code>pointer-events: all</code>).
	</p>
	<p>
	Combine the pointer-event disable with setting the opacity of the
	center filter column to 0 and it appears that you are interacting
	directly with the underlying layer (the avatar layer); effectively
	punching a hole through the dead space on the top layer to the one
	underneath.
	</p>

	<div id="instructions">
	<h2>Instructions</h2>
	<p>
	Click an avatar to expand, click it again after expanding to select.
	You can use the buttons below as well. Hover the two controls on the
	left and right to watch them expand without the avatars moving at
	all. Resize the screen and watch as the avatars stay perfectly
	centered.
	</p>
	<p>
	<strong>Reset</strong> will stack all of the avatars on top of one
	another. <strong>Expand</strong> will show the full expansion where
	each avatar has breathing room. <strong>Collapse</strong> will put the
	avatars back into the fan-out stack, which is the default
	representation.
