#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 let me know if you use Pushy in one of your websites.

##Install

Download the packaged source file, this includes everything you need to get Pushy running on your site.

Add the stylesheet (pushy.css) in your head and the JS (pushy.min.js) file in your footer.
If you are using submenus, then you'll need to add the arrow.svg file into your img directory (optional).
Insert the following markup into your body.

<!-- Pushy Menu -->
<nav class="pushy pushy-left">
    <ul>
        <!-- Submenu -->
        <li class="pushy-submenu">
            <a href="#">Submenu</a>
            <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>
</nav>

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

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

##Bower

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

bower install pushy

##Tips

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">
    <ul>
        <li class="pushy-link"><a href="#">Item 1</a></li>
        <li class="pushy-link"><a href="#">Item 2</a></li>
    </ul>
</nav>

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">
    <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>
</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;
}
