Tachyons comes with two convenient modules to help debug layout issues you might be having.
The debug_children module allows you to use a class called "debug" on any element. That element along with any child node will have an outline of 1px solid gold placed on it.
The debug module is commented out at the bottom of the src/tachyons.css file. If you uncomment it a 1px outline will be placed on every element on the page. Each element has a different color outline. The purpose of this is to help distinguish elements that are close together by giving them different colors. This has been helpful at times when the outlines are overlapping by 1 or 2 pixels and it's hard to tell where one element ends and the other begins.
