Let's try to control the start and stop
values for the colours in our
radial-gradient. Here's an example:
In the above example, the gradient starts with
red at 20% of the radial distance,
transitions to yellow at 30%, and
then transitions to green at 40%.
In the above example, the
gradient has four color stops red
from 0% to 20%, blue from 20% to 40%,
yellow from 40% to 60%, and
green from 60% to 100%.
The start and end percentages
for each colour stop are specified, resulting in
no mixing or overlapping of colours.
