CSS and Javascript web development library that supplements Bootstrap.
For various fullscreen functionality of the Pineapple Library (Banner, Fullscren YouTube videos, etc), you will need to define the following somewhere in your css before it will take effect:
html,
body {
height: 100%;
}
Ajax allows you to replace the contents of an element with the contents of another HTML file without needing to reload the page. This can be accomplished by using the Javascript onclick function on the element you want to trigger the Ajax call. You then pass the path or URL to the content you’d like to swap in and the ID of the element where you want it to end up.
<div id="pa-ajax-content">
<button class="btn" onclick="pineapple.ajax('ajax.html', 'pa-ajax-content')">Press to make an Ajax call</button>
</div>
The .pa-animate-bottom class will give any object a sliding-in effect from the bottom of the screen upon page load. This is a simple way to add some visual effects to your page. Best if used on the <body> tag.
Create a customized countdown timer that updates each second and displays a message once the countdown is reached.
<div id="timer"></div>
<script>
pineapple.countdown.init(
'2018-12-15', // date to countdown to
'timer', // timer ID
'Timer has expired' // message displayed once countdown has expired
);
</script>
The .pa-nav-fade allows the navbar to fade in after scrolling past a certain pixel threshold. By default, if there is a pa-banner class on your page, the height of that element will be used. You can define your own value for when it should fade if desired:
<script>
pineapple.navFadeThreshold = 1000;
</script>
.pa-nav-fade {
/* Use a transparent nav background for full-screen banner images */
background-color: transparent;
color: #000;
}
.pa-nav-fade.opaque {
/* Fill in the nav background once we've scrolled past the full-screen banner image */
background-color: blue;
}
.pa-nav-fade a {
color: #fff;
}
.pa-nav-fade .dropdown-menu a {
color: #000;
}
.pa-nav-fade a.opaque {
color: #fff;
}
The .pa-loader and .pa-loader-div are used to create a loading spiral image upon opening your page. This is great if you have external content that needs to load and you want something visual to display while this happens. You can do this by using the following just after your <body> tag: <div id="pa-loader"></div> and <div id="pa-loader-div">. (Place the end </div> tag at the bottom of your page content you want hidden while the loading spinner is on screen.
<body onload="pineapple.pageLoader()">
<div id="pa-loader"></div>
<div id="pa-loader-div">
<!-- page content goes here -->
</div>
<script>
pineapple.pageLoader(1500); // the number of milliseconds to pause on the page loader, default is 1500
</script>
</body>
The .pa-slideanim class will give any element a sliding-in effect once the element comes into the viewport. This is a simple way to add some visual effects to your page. Best if used on elements that appear below the initial viewport of the page (eg: below the top items that load when a user first visits the page). This is a simple way to add some visual effects to your page.
Whenever a nav link (with a class of “nav-link” or “navbar-brand”), link, or link with the role of a button is selected on the same page as its anchor, the page will scroll smoothly to that portion of the page (this feature is enabled by default). Additionally, you can add the .pa-scroll class to any item with an anchor to have it scroll to that spot on the page. If you’d like to disable this feature for certain elements, you can simpley add the .pa-noscroll class.
Alternatively, you can disable Smooth Scrolling globally:
<script>
pineapple.disableSmoothScrolling = true;
</script>
Create stylized backgrounds.
Wrap a .pa-slanted-content <div> in a .pa-slanted-container <div> to create a slanted break in the page. Style as needed.
<div class="pa-slanted-container">
<div class="pa-slanted-content">
<p>Slanted Section</p>
</div>
</div>

The .pa-banner class will create a fully scalable “landing page” style image and appropriate text-scaling. (see below for details on text scaling)
The .pa-banner-darken class will darken your banner image to allow text overlayed over the banner to be seen easier.

The .pa-banner-sub-heading scales a sub-heading title in the banner based on screen size.
The .pa-banner-text scales normal paragraph text in the banner based on screen size.
