Smoother Burger Menu Transition

Hi Guys,

I have a burger menu for mobile screens, and I'm using Jquery to toggle a class changing the height. Here is my code:

HTML: 

     <a class="btn-menu" href="#"><span>MENU</span></a>
        <div class="nav hide">
            <ul>
                <li><a href="#">Home</a></li>
                <li><a href="#">About</a></li>
                <li><a href="#">Media</a></li>
                <li><a href="#">Contact</a></li>
            </ul>
        </div>

Sass: 

/*========================
 Base Styles
 ========================*/

.hide {
height: 0;
overflow: hidden;
}

.show {
height: 100%;
}

/*========================
Navigation
========================*/

.header {
background-color: $background;
.logo {
    margin-top: 5px;
    display: inline-block; 
    img {
        margin-left: 5px;
        width: 200px;
        height: 65px;
    }
}
.nav {
    ul {
        padding: 0;
        padding-bottom: 10px;
        li {
            list-style-type: none;
            text-align: center;
            padding: 7px;
            background-color: $orange;
            border-radius: 10px;
            box-shadow: 2px 3px 5px black;
            margin: 8px auto;
            width: 80%;
        }
        a {
            text-decoration: none;
            color: $blue;
            font-size: 1.2em;
            font-weight: 500;
            display: block;
            width: 100%;
        }
    }
}
}

jQuery:

<script> $(".btn-menu").click(function(){ $(this).toggleClass("btn-menu-open"); $(".nav").toggleClass("show"); }); </script>

This works, however I was hoping to use a transition to make the change of width smoother over 2s. Any help will be much appreciated!

Thanks in advance!

Matt

Since you already have JQuery, try this: in the HTML remove the "hide" class from the div, and in the JavaScript replace toggleClass("show") with slideToggle(2000).

Personally, I think 2 seconds (2000 ms) is a bit long.

2 Seconds was a bit long, changed to 1s. This is exactly what I'm looking for however, I need the code to hide the menu on load and show the menu on click? This solution shows the menu on load and then when I click the button hides the menu... ideally I need this to be reversed?

Thanks for your help!

:point_right: No problem. Just add this line to the bottom of your JavaScript to make it hidden initially:

$(".nav").hide();

:information_source: FYI: You can use the string "slow" as the argument to slideToggle() for a peppier but smooth 800 ms.

jQuery('a.btn-menu').on('click', function(event) { event.preventDefault(); jQuery('.nav').slideToggle(200); });

You can leave .hide on your nav this way.

Thanks both for your help! In the end I read the jQuery documentation for slideToggle() and set the .nav to "display: none" in the css, this is the desired effect needed.

The $(".nav").hide(); also worked, however there was a split second I could see the menu on load before the browser got to the javascript and hid the menu.

Thanks again for your help!
