javascript - How to get a leaflet map canvas to have a 100% height?

Question

My leaflet canvas currently looks like the following, with a 700px height:

However I would like its height it be 100%, in order to take the whole white space.

height:100% doesn't work in the CSS properties of the map canvas. I found a few solutions but they are only good for Google Maps.

Does anybody has a solution, even if it's only a workaround ? Thanks !

The best way is to use the CSS length units vh and vw. These allow a block-level HTML element to have a dimension relative to the viewport size, instead of the size of its parent element (as % does).

e.g.:

#map {
  width: 100vw;
  height: 100vh;
}
