Definition
The CSS margin-bottom property allows us to specify the margin space below the padding and border for an element.
Applies To
All elements except elements with table display types other than inline-table, table and table-caption.
Property Values
CSS allows specification of a margin width.
negative values are acceptable for when you want to overlap elements.
auto - The browser sets the bottom margin and this can vary from browser to browser.
inherit - The margin-bottom properties are inherited from the parent element.
length - Defines a bottom margin space in a unit measurement such as em or pixel.
n% - A percentage value relative to the parent element where n is a number.
Default Value
Default value of margin-bottom is set to 0.
Inheritance
The margin-bottom property is NOT inherited from the parent element unless specified using the inherit property value.
Browser Anomalies
IE5, IE6 and IE7 do not support the inherit property value.
IE8 does with a valid !DOCTYPE.
IE9+ supports the inherit property value.
As mentioned above setting the property value to auto is browser dependant.
