Work with legacy and simple sites using jQuery selectors, events, AJAX, effects, and plugins.
Lessons
Use slideDown, slideUp, and slideToggle.
Sliding Effects is easiest to learn by reading the example, changing it, and observing the result.
$('#menu-toggle').on('click', function () {
$('#menu').slideToggle(300);
});
$('#open').on('click', () => $('#panel').slideDown());
$('#close').on('click', () => $('#panel').slideUp());Practice the Sliding Effects example in a small scratch file, then explain what changed and why.
