margin-left (CSS2)

The CSS3 border-radius property allows web developers to easily utilise rounder corners in their design elements, without the need for corner images or the use of multiple div tags or JavaScript.

jQuery.support is a collection of properties that represent the presence of different browser features or bugs. Primarily intended for jQuery's internal use; specific properties may be removed when they are no longer needed internally to improve page startup performance.

The jQuery slideUp and slideDown methods gradually change the height of the selected elements.

jQuery.browser contains flags for the useragent, read from navigator.userAgent. We recommend against using this property; please try to use feature detection instead (see jQuery.support). jQuery.browser may be moved to a plugin in a future release of jQuery.

CSS margin and padding properties are used to spacing out the elements. A margin is the space outside of the element, whereas padding is the space inside the element.

This example shows you how to use an internal CSS StyleSheet to apply margin options. The top line has no margin, whereas the second line of text has a margin on both sides of 50px.
