Hi everyone,

Can anyone explain me why some tags are highlighted in light grey? The text of some tags (divs) appears grey...
I have just started doing some html and css coding so unfortunately I'm not able to tell if I am doing anything wrong with my codes. I am happy with the way things appear on the page but I'd like to know why that particular object is highlighted. Here is the link. It's the div id="tag"...

Any help would be much appreciated!

Thanks

I don't really get the question. Do you mean gray in Firebug or in the browser?

Firebug usually set elements to light gray when they are hidden.

There's not much that the built-in Chrome Developer Tools can't do that Firebug can. Either way, Firebug is still an amazing plug-in.

One problem with Firebug is that when the page URL changes, the Net logging console resets/clears, giving you no ability to see what just happened if the page does an HTTP redirect. There are plans to fix this in version 1.5 of Firebug, but for now you're left with using Wireshark instead.
