Pushy

Pushy is a responsive off-canvas navigation menu using CSS transforms & transitions. This project was inspired by the off-canvas navigation menu seen on Medium.

Pushy has been implemented on many sites, check them out! Feel free to contact me if you use Pushy in one of your websites.

Pushy has been featured on the Treehouse Show and in a book!

Install

Download the latest release, this includes everything you need to get Pushy running on your site.

1. Add the stylesheet (pushy.css) in your head and the JS (pushy.min.js) file in your footer.

2. If you are using submenus, then you'll need to add the arrow.svg file into your img directory (optional).

3. Insert the following markup into your body.

<!-- Pushy Menu -->
<nav class="pushy pushy-left">
    <div class="pushy-content">
        <ul>
            <!-- Submenu -->
            <li class="pushy-submenu">
                <button>Submenu</button>
                <ul>
                    <li class="pushy-link"><a href="#">Item 1</a></li>
                    <li class="pushy-link"><a href="#">Item 2</a></li>
                    <li class="pushy-link"><a href="#">Item 3</a></li>
                </ul>
            </li>
            <li class="pushy-link"><a href="#">Item 1</a></li>
            <li class="pushy-link"><a href="#">Item 2</a></li>
        </ul>
    </div>
</nav>

<!-- Site Overlay -->
<div class="site-overlay"></div>

<!-- Your Content -->
<div id="container">
    <!-- Menu Button -->
    <button class="menu-btn">&#9776; Menu</button>
</div>

Development

Pushy CSS and JS are compiled and minified using Grunt. You'll need Node and Grunt installed globally.

From the root directory run:

$ npm install
$ grunt

Now you can edit files in /scss/ and /js/, which will be compiled to /css/pushy.css and /js/pushy.min.js automatically.

CDN

Link directly to Pushy files on cdnjs.

NPM

If your are comfortable with command line, you can install Pushy as a NPM package:

npm install @cmyee/pushy

Options

Menu Position

Use the .pushy-left or .pushy-right CSS class to specify the menu position.

<!-- Pushy will transition from the right -->
<nav class="pushy pushy-right">
    <div class="pushy-content">
        <ul>
            <li class="pushy-link"><a href="#">Item 1</a></li>
            <li class="pushy-link"><a href="#">Item 2</a></li>
        </ul>
    </div>
</nav>

data-focus

Use the data-focus attribute to give focus to a link when the menu is opened. Ideally the first link of the menu should be focused.

This data attribute accepts a CSS selector.

<nav class="pushy pushy-left" data-focus="#first-link">
    <div class="pushy-content">
        <ul>
            <li id="first-link" class="pushy-link"><a href="#">Home</a></li>
            <li class="pushy-link"><a href="#">About Us</a></li>
            <li class="pushy-link"><a href="#">Contact</a></li>
        </ul>
    </div>
</nav>

data-menu-btn-selector

Use the data-menu-btn-selector attribute to change the menu button CSS class for toggling the menu.

By default Pushy will use .menu-btn to toggle the menu.

This data attribute accepts a CSS selector.

Note: In v1.4.0 this attribute was renamed from data-menu-btn-class to data-menu-btn-selector

<!-- Pushy Menu -->
<nav class="pushy pushy-left" data-menu-btn-selector=".my-menu-btn">
	<!-- I've removed the inner markup for brevity -->
</nav>

<!-- Menu Button-->
<button class="my-menu-btn">Menu</button>

data-container-selector

Use the data-container-selector attribute to using a custom #container selector.

If you use a custom #container selector you'll need to update the necessary CSS in pushy.scss.

This data attribute accepts a CSS selector.

<nav class="pushy pushy-right" data-container-selector="#custom-container">

Tips

• Use the .push CSS class on HTML elements outside of the #container.

<header class="push">
    <h1>This is a Heading</h1>
    <h2>This is a subheading</h2>
</header>

<!-- Your Content -->
<div id="container"></div>

• If you are using SCSS, you can easily change the menu width by adjusting the $menu_width variable. The SCSS file will need to be compiled to CSS in order to see the change.

$menu_width: 400px;

• Not using SCSS? You'll have to update the multiple values (or do a find a replace!) in the pushy.css file.

.pushy{
    width: 400px; /* Changed the width to 400px */
}

.pushy-left{
    transform: translate3d(-400px,0,0); /* Updated the values */
    /* Don't forget the vendor prefixes */
}

.pushy-open-left #container,
.pushy-open-left .push {
    transform: translate3d(400px, 0, 0); /* Updated the values */
}

.pushy-right {
    transform: translate3d(400px, 0, 0); /* Updated the values */
    /* Don't forget the vendor prefixes */
}

.pushy-open-right #container,
.pushy-open-right .push {
    transform: translate3d(-400px, 0, 0); /* Updated the values */
    /* Don't forget the vendor prefixes */
}

• Only links with the CSS class of pushy-link will close the menu.

<nav class="pushy pushy-left">
    <div class="pushy-content">
        <ul>
            <!-- This link will close the menu -->
            <li class="pushy-link"><a href="#">Item 1</a></li>
            <!-- This link won't close the menu -->
            <li><a href="#">Item 2</a></li>
        </ul>
    </div>
</nav>

• If you want to prevent scrolling of your site when Pushy is open just add overflow-x: hidden and height: 100% to both the html & body tags.

html, body{
    overflow-x: hidden;
    height: 100%;
    -webkit-overflow-scrolling: touch;
}
