jQuery function , Selectors, Fade effect.

jQuery function

• You use this to select elements from an HTML page to manipulate.
• The $ shortcut means you don't have to type “jQuery" over and over.
• The jQuery function can handle selectors, straight HTML, and even JavaScript objects.

Selectors

• jQuery selects elements the same way CSS does: with selectors.
• Just about any kind of HTML element is fair game for a jQuery selector.

Fade effect

• Once you've selected an element, you can fade it in a variety of ways, using FadeIn, FadeOut, FadeTo, and FadeToggle.
• You can fade in all kinds of elements, from text to images and more.
• Control the speed of your fade effect by putting a time (in milliseconds) value inside the parentheses at the end of the statement.
