No, it’s not, although there is an open post for such a feature on the [ideas forum](https://ideas.inductiveautomation.com/ignition-features-and-ideas/p/expose-viewport-dimensions-in-perspective). ---

Be aware that pixel dimensions of various DOM elements are used in [browser fingerprinting](https://panopticlick.eff.org/), and browsers are actively trying to prevent that. Depending on javascript access to DOM dimensions is fraught with peril, or at least maintenance headaches. ---

So, could you please tell how to overlays component overlay on the map without causing it’s size scale when browser change size? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/6/67e431519e7a1a688932674461b0f27855e1f62e.png) For example how did you manage to maintain the zoom in out icon on map fix all the time? 1- I set z-index of map to 0 so I can now put item on map easily. 2 - I use coordinate with percent mode so map fill all the view area and can overlay other component on it. 3- This mode cause my elements scale and which is not wanted here. I’d like the size of them to be fix all the time like the map zoom button.
