Css3Renderer white border

I am using the CssRender and it have an annoying white border (see the picture)
How can I remove that?

@Antonio_Casula Hi :grinning:,can you share your test project link so we can have a check?

This type of white-border is somewhat a known issue to be caused by the HTML background being offsetted for various reasons, whether intentionally or unintentionally.

You can re-position your HTML background’s position to correctly display it by resetting its margin/padding:

html, body {
  margin: 0;
  padding: 0;

If the issue still persists, perhaps considering to go old school and simply match your HTML background’s color with your green panel’s background color.


#green-panel {
    background-color: green;

@FBPlus Thanks for answer! here is:


Sorry @RPaladin but, it’s not a problem with the hosted page …

Hi @Antonio_Casula! It’s completely white on my laptop.

I concur with @Albertos, apparently your resource server is blocking any external access outside of your own address/token?

A link to the editor page of your project should be usefull. Please make sure your project is not private, otherwise other users are unable to see your project.

I don’t see that warning/error message anywhere.

ops! this is the editor view:


I don’t get the blocked resource error anymore, however, for both Play & Editor project links I still am getting a blank screen… Maybe it’s my browser…
