jquery add to class code example

Example 1: jquery add class

$('some_element').addClass('some-class');

// You can add more than one class at one time
$('some_element').addClass('some-class another-class yet-another-class');

// Even thought jQuery allows you to do this
$('some_element').addClass('some-class').addClass('another-class').addClass('yet-another-class');

// That would be really wasteful, think of the planet!
// But more importantly, your RAM
// oh and those poor folks who be viewing your website
