display old label style in new R leaflet 2.0

Viewed 231

The R leaflet labels have changed in the latest release 2.0 and now have a solid white background without a border. Is there a way to print a label that's similar to the old style without installing an old version?

leaflet() %>% addTiles() %>%
  addMarkers(
    lng=-118.456554, lat=34.078039,
    label='My label',
    labelOptions = labelOptions(noHide = TRUE))

You can achieve something similar by overriding the css, place the following code in your own CSS that is called after leaflet.css

.leaflet-tooltip{
    border:4px solid rgba(0, 0, 0, 0.7);
    background-color: rgba(255, 255, 255, 0.8);
}

You can play with the values to make it look any way you want, this goes for pretty much any element in leaflet, like the popups.
