Add font to index.css

[jtmiclat]

What I am changing

Add missing css to lonboard tooltip

How I did it

The problem is that when inside a jupyter notebook, the tooltip (and other html elements) inherit some css from jupyter lab/notebook compared to running it in exported form. In this cases, it was the font.

Here is the css of the tooltip when in jupyter lab. The one declaring the font is not related to the css of lonboard but the css of the body.

vs css of the tooltip when exported

To fix this I added the missing font to the lonboard css.

How you can test it

Export map

import geopandas as gpd
from lonboard import viz

gdf = gpd.read_parquet(...) # any file will do
map = viz(gdf)
map.to_html("test.html")
