HTML Mocker Demo
This script periodically randomizes the contents of your HTML tags to make it easy to test if your layouts will remain responsive with unexpected dynamic data. It can randomize text length, # of words in a text node, width and height of images via Unsplash, number of children elements (with recursion) and more.
The idea is to detect bugs during development and without having to do manual testing for various boundary conditions of data. This is a work in progress. You can file issues and send PRs on the GitHub repo.
