you can select them in different ways
Here you can select the elements by number…
$("div").children(':nth-child(1)').css("background", "red");
// $("div").children(':nth-child(1)').html(); // for content
or
$("div p:nth-child(1)").css("background", "red");
than you could use the first-child selector
$("div").children(':first-child').css("background", "red");
or
$("div p:first-child").css("background", "red");
