jQuery - jQuery Slide Effects

 

 What Are jQuery Slide Effects?

jQuery slide methods change the height of an element, making it appear or disappear smoothly by "sliding" open or closed. It's perfect for things like menus, FAQs, or hidden messages.

 1. slideUp()

This makes an element slide up and disappear (like closing a curtain).

$("#box").slideUp();

You can add speed:

$("#box").slideUp(1000); // slides up in 1 second

 2. slideDown()

This makes a hidden element slide down and appear (like opening a drawer).

$("#box").slideDown();

Add speed if you want:

$("#box").slideDown("slow");

 3. slideToggle()

This switches between slideUp() and slideDown()—great for toggling visibility with one button.

$("#toggleBtn").click(function() {
  $("#box").slideToggle();
});

 Real Example:

<button id="toggleBtn">Show/Hide Box</button>
<div id="box" style="width:200px; height:100px; background:lightblue; display:none;"></div>

<script>
  $("#toggleBtn").click(function() {
    $("#box").slideToggle("fast");
  });
</script>

 When you click the button, the box slides down if it's hidden, or slides up if it's visible.
