html - Inspecting Hover-state in Firebug or Chrome DevTools

Question

I've got an HTML element that has a CSS hover-state. There's a bug with the margin or padding on hover and every time I mouseover, the contents of the element slide a little, its annoying.

I'd like to debug using FireBug or Chrome Dev Tools, but a common problem I've had with these tools is that after I select the element from Firebug/devtools I obviously need to move the mouse back to the dev tools and the hover state is no longer enabled.

How do I inspect/debug an HTML element using these tools with the element in its hover state?

Answer 1

Chrome Dev Tools has a built-in :hover state selector in the Elements > Styles panel. You can toggle other pseudo-classes (like :active) there as well.
