The current iteration of https://derivationmap.net/ uses data from a JSON file to dynamically generate page content.
On the front page of https://derivationmap.net/ there's currently an SVG. I wanted to place a PNG next to the SVG. Before placing the PNG, I wanted to make the SVG narrower. Looking at the source code for the page index.html, I see
Inspecting the source code of the rendered page, I see
var width = 600;
To test out a change to a narrower width, I start "Docker desktop" on my Mac and, in the directory
allofphysicsgraph/proofofconcept/v7_pickle_web_interface, run the command
docker-compose up --build --remove-orphans
In a web browser I was then able to access http://localhost:80 and got a warning from Chrome that the certs were invalid. Incognito mode seemed to be working better.
