Firefox Dev Ed is a great browser for web development and tweaking CSS. But sadly it does not always show default property values. A classic example of this is the <ul> element's default ''padding-left'' property. This apparently is set at ''40px'' automatically unless overridden by the web designer. I think that '''ALL inherited or default properties of elements ought to be clearly shown in the inspect tool's styling listings.''' You could spend hours maddeningly trying to find the cause of some of these offsets to what you expected to display. The curious thing is that '''some''' inherited or default property values are shown on the inspect tool - which leads us to assume that what is seen on inspect is all that there is . . . This change should not be too difficult to implement. And it would be a great thing to have when searching down unexpected behaviour in webpage displays.
