Question

$("p") references all paragraphs on the current web page. Is it possible to execute code for each element that matched the selector?

Here’s a simplistic example in pseudo-code:

// Show the background color of every paragraph on the page
foreach (object = $("p")) {
  alert(object.css("background-color"));
}

Answer 1

$('p').css('background-color', 'black')

If you need more flexibility:

$('p').each(function() {
    $(this).css('background-color', 'red');
});
