Customizing Size of LinearColormap

Is there a way to resize the colormap?
Line 147 in cd22245
I'm testing this on mobile and it looks a bit off.
I was running into this, too. The _repr_html_() method uses a fixed width of 500, which is a bit unfortunate because one cannot use it in an arbitrary context. See this image.
It would be nice to give the colormap instances a width attribute that could be used by the _repr_html_() method. A workaround would be to scale the returned SVG which you can using code below, but it will also scale the number labels:
import io
from branca.colormap import step
from ipywidgets import HTML
from reportlab.graphics.renderSVG import drawToString
from svglib.svglib import svg2rlg
colmap = step.Accent_03
drawing = svg2rlg(io.StringIO((colmap._repr_html_())))
drawing.scale(0.5, 1)
scaled_svg = drawToString(drawing)
HTML(scaled_svg)You're right that currently the color scales have a fixed size. I get that you may want to change that. While looking into this I tried something out to add this functionality. Maybe you want to test it?
If we scale the thing, is the numbers also resizing a good or a bad thing?
Scaled (squeezed or stretched) would be very ugly. One might want to drop them entirely and leave only ticks as an option. In the end it’s a simple mini plot with its own axis which can easily mean introducing a bunch of config options...
I'll try, but I don't see any info about building it locally.
