use the browsers developer tools.  e.g. for chrome it is Ctrl+Shift+i or F12

More information here:

I often right click on an element on the page and click "inspect".  This also brings up the devtools, specifically targeting that element.  That's important as you can see on the CSS/Styles panel exactly what CSS has been applied AND what has been overridden.

What is the user agent style in the inspect window ... the one that I can't  see in my coding....

RobOwner (Aidellio)Commented:
You can find the user-agent on the network tab.  Just reload the page and look at any of the requests made by the browser. Is that what you are after?

I mean the one shown in the attached file.. Is it the one that applied by default browser setting ?

RobOwner (Aidellio)Commented:
Ah I see... for your nav element, yes the "user agent" is what the browser does by default.  In this case, just displays as "block"

Then above that I can see you're applying a custom style (can't see the actual file) to the nav element.

At the top of that window, click "computed" to see all the styles that affect that element.
