I am confused by these colors. I noticed that in the left column of the FireBug DOM DOM tree, four colors are shown:
- Bold black
- The black
- Bold green
- Green
In the right column:
- blue
- Red
- Bold green
- Green
- Several color elements representing the structure of objects.
What are these colors? And why, for example, can I access window.document.URL, and I can’t access window.document.body in the console, although they are both in the non-greasy black category in the DOM tree?
thanks a lot
