JQuery: Syntax

The jQuery syntax is tailor made for selecting HTML elements and perform some action on the element(s).
Basic syntax is: $(selector).action()

• A dollar sign to define jQuery
• A (selector) to "query (or find)" HTML elements
• A jQuery action() to be performed on the element(s)

Examples:
$(this).hide() - hides current element
$("p").hide() - hides all paragraphs
$("p.test").hide() - hides all paragraphs with class="test"
$("#test").hide() - hides the element with id="test"
