How to ensure that all markers are visible when there is a custom GUI obscuring a portion of the map?

[glocore]

I'm plotting a set of markers on my map by setting their lat/long values, but I also have a translucent "HUD-style" UI obscuring a portion of the map, as shown in the image below. Some of the markers are under this HUD, and I need to drag the map to be able to see them/click on them. The HUD is a simple absolutely-positioned div.

My setup looks roughly like this:

<Map>
  <Hud/>
  <Marker/>
  <Marker/>
  <Marker/>
</Map>

Is it possible to define some kind of "safe zone" for the markers, so that they don't get obscured by custom overlaying UI? Or are there any other options to ensure that all markers are visible when the map loads?
