Close button for sticky element

[Sonya*]

I need a close button for a sticky element. The code I have:

<div id='cfWrapper'>
	<div id='cfSticky' data-ipsSticky data-ipsSticky-stickTo='bottom' class="ipsType_center ipsType_richText">
      The content of the sticky element using IPS template syntax.
   </div>
</div>

I need a button (a small cross in the right upper corner of the sticky element) that closes (removes) the sticky element. Desired features:

• Select what groups can see and use the close button
• Add a timer to display the element again after X milliseconds of time.

Alternative to sticky it can be simply a message like Guest Terms bar, placed at the bottom of the page.

Who can code this? 😏
