$("#results tr:first").css("background", "black");

$("#results tr:first").addClass("header");


//All span that are inside a div element (may not be immediate child of the div) will be selected.
$("div span").css("border", "1px solid");

//Here is how we can select a div with id mydiv 
$("div#mydiv")


// Here is how we select all links under div elements that have css class set to mycss
$("div.mycss a")

// if we want to find a link that points to http://www.google.com then we would write
$("a[href=http://www.google.com]")

$("div#mydialog").html("
Hi There!
");
$("#mytable").wrap("
");
