Have you ever found yourself either writing a CSS selector that winds up looking confusing as heck, or seen one while reading through someone's code? That happened to me the other day.

Here's what I wrote:

.site-footer__nav a:hover > svg ellipse:first-child { }

At the end of it, I honestly couldn't even explain what it does to myself. LOL, that probably means there was a better way to write it.

But Hugo Giraudel has this handy new tool that will explain any selector you throw at it.

Here's how it explained mine:

An <ellipse> element provided it is the first child of its parent somewhere

… within a <svg> element

… itself directly within an <a> element provided it is hovered

… itself somewhere

… within an element with class site-footer__nav .

Bravo! It even spits out the specificity of the selector to boot. 
