- Create a large mapframe, e.g.:
<mapframe text="some text" latitude=55.596667 longitude=38.145833 zoom=14 width="900" height="900" align="center">
{
"type": "ExternalData",
"service": "geoline",
"ids": "Q4277109",
"properties": {
"stroke-width": 4
}
}
</mapframe>- Decrease browser's width, or increase font size (ctr-+)
- Observe that the moment mapframe is wider than the screen, there is a lot of extra space at the top and at the bottom
