Chrome Developer Tools: How to find out what is overriding a CSS rule?

Question

Well, this is pretty straightforward. If Chrome's Developer Tools is showing me that a style is overridden, how to see what CSS rule is overriding it?

I want to know if is there anything like "Show me what overrides this".

OBS: Please, don't point me to Firebug.

Chrome's Developer Tools also show you the overriding rule – Wicket

Answer 1

Use the Computed Style panel of the element inspector. Expand the property of interest to see the list of applicable rules, and which one won.

For me the computed tab was open at default and therefore not listed as a tab, it should have had a header 'Computed', otherwise you could be looking for a long time. – Calvert

The technique has changed a little as Chrome has advanced. Instead of 'Expand the property of interest' click the spy-glass next to the property and it will show which style won back in the Styles tab. – Upbear

@intotecho: Chrome 47 has restored the expando in the Computed tab since the magnifying glass change sucked. crbug.com/496263 – Stochastic

what if ALL of them are cancelled? Probably due to a script? How do you find out who did it? – Brain

It's still there as the "Computed" tab on the Elements panel. – Stochastic

@josh3736,maybe my css has !important but can't find anything overriding in Computed or elsewhere – Bonkers

I would avoid trying to use !important to begin with. When you start tossing multiple css libraries into the mix, and then you add your own styling yielding unexpected results, you are in for an action-filled evening. – Manley

Answer 2

You can simply look at the ones with the same name which aren't striked out, remember the listing is by importance.

Or you can view the computed styles. They will be the actually applied styles.

Answer 3

crtrl + shift + c and inspect the element. Then find the style without a line through it, in the box in the down right corner.

the override is in most cases at the top (and without a line through it, as this style is the "winning" one).

It's not the case when a style is flagged as !important – Expedition
