Hiding skin when using a hash link with a hotspot

[petersmall]

I want to be able to use a hash link to bring up a popup image when I click on a hotspot (i.e., URL = #MyImage).
This works fine except that the skin (control buttons) is visible over the image. How can I arrange for the skin to be under my image (or to be invisible)?

Hi Peter,
Can you post your skin?

Hi Hopki,

It doesn't happen in the skin. The skin can be any skin.
The popup is triggered from the URL field of the hotspot
i.e., #myPopUp
This hash link takes the page view to a <div> with an id name matching the hash call
i.e., <div id = "myPopUp">
This div (with its class i.e., class="popUp1") describes the popup but has an opacity = 0, which means it does not show on the page.
However, if a pseudo class is created:
.popUp1:target {opacity:1; pointer-events:auto;}
This can reset the opacity to 1 - allowing the popup to be visible when the hash link is called.

This technique is described in detail in:

What it needs now is for the pseudo class to be able to make the skin disappear - or at least the control buttons

regards

Peter
