Implementation of a horizontal slider component with Stimulus and Tailwind CSS

	<!--
	This code is meant to accompany the guide originally published at https://colby.so/posts/building-a-horizontal-slider-with-stimulus-and-tailwind
	It intentionally pulls in Tailwind CSS and Stimulus without a build system to simplify the guide. You shouldn't do this with a real application,
	you should use a build system like webpack!

Method for finding pythagorean triples in a given range. Returns the triple with the largest sum that is less than the given perimeter

	def find_biggest_triple(perimeter)
	all_triples = [] # Empty array to hold all of the triplets
	max_side_length = perimeter/2 # This isn't necessary because we filter but the method runs a lot faster if we cut down how many times the all_triples loops need to run. a + b should always be greater than c so no need to build triples that won't be selected

	# Run outer loop perimeter/2 times - This is our hypotenuse
	max_side_length.times do \|a\|
	a.times do \|b\|
	b.times do \|c\|
	# Pythagorean triplet is found if the square of the two shorter sides (the two interior loops) equals the square of the hypotenuse
	if c2 + b2 == a**2
