Scroll Watch

Skill Level: 
Advanced

The Scroll-Watch Plugin gives you specific controls over band imagery. In the sections below we will examine the different types of band imagery scroll-watches that can be implemented. The specific modifiers for each will be listed out and links to an example page will be given.

The Scroll-Watch plugin encompasses a variety of effects. Start with a <div class="wdn-band"> add place a div nested in it. Apply the wdn-scroll-watch class to it, which should look like this: <div class="wdn-scroll-watch">. You will also need to initialize it with the following JavaScript:

<script>
    WDN.initializePlugin('band_imagery');
</script>

Add the desired effect properties to that same div (these are gone into detail below). Enter in the property values that give you the desired effect. Save, test and revise as needed.

Band Imagery, Scroll-Watch Plugin Samples

Scale

Scale properties control the scaling applied to the band image. By setting different values you can control when and how much an image will scale.

data-lerp="scale" Tells the plugin to use the Scaling effect.
data-lerp-scale-start="#attribute1" Tells the plugin when to begin the effect.
data-lerp-scale-end="#atribute2" Tells the plugin when to end the effect.

The scale-start and scale-end are set to trigger at specific IDs. These could be existing page IDs, like #header or #maincontent or a custom ID that you place on your page, such as #scalestart and #scaleend. Use a naming convention that helps to easily identify it.

data-scale-start="1" Tells the plugin what size the image should be at the beginning of the effect.
data-scale-end="1.1" Tells the plugin what size the image should end at.

The data-scale-start and data-scale-end values can range from .1 to 3 or more. The value represents percentage of size; .1 equals 10% of original size while 3 would be 300%.
Example of Scale

Here's how you do it Source code


<div class="wdn-band">
        <div class="wdn-stretch wdn-scroll-watch" data-lerp="scale" data-lerp-scale-start="#header" data-lerp-scale-end="#maincontent" data-scale-start="1" data-scale-end="1.1">
            <figure>
              <img src="samplecontent/unsplash_525a7e89953d1_1.jpg" alt="Black and white sunset">
         </figure>
        </div>
    </div>

Opacity

Opacity properties control the opacity of the band image. By setting different values you can control when and how opaque an image will start and end at.

For this effect you will want to choose a background-color for the wdn-band the opacity div will be nested in. Whatever color you choose will show through when your band image's opacity drops, so keep that in mind.

data-lerp="opacity" Tells the plugin to use the Opacity effect.
data-lerp-opacity-start="#attribute1" Tells the plugin where to begin the effect.
data-lerp-opacity-end="#attribute2" Tells the plugin where to end the effect.

The opacity-start and opacity-end are set to trigger at specific IDs. These could be existing page IDs, like #header or #maincontent or a custom ID that you place on your page, such as #opacitystart and #opacityend. Use a naming convention that helps to easily identify it.

data-opacity-start="1" Tells the plugin what opacity to start at.
data-opacity-end="0.0" Tells the plugin what opacity to end at.

The data-opacity-start and data-opacity-end values can range from 0.0 to 1. The value represents percentage of opacity; 0.0 equals 0% opacity (or completely transparent) while 1 would be 100% (or fully opaque).

Our code example uses a slightly different way of implementing the start and stop of the Opacity effect. Here we rely on absolute positioning applied to our divs: <div id="opacity-start" style="position:absolute; bottom:75%;"></div> and <div id="opacity-end" style="position:absolute; bottom:10%;"></div>. This gives us a beginning and end to the effect relative to the page position of our band, it could be applied to any of our Scroll Watch effects, so play around with different techniques.

Example of Opacity

Here's how you do it Source code


  <div class="wdn-band" style="background-color:black;">
         <div class="wdn-stretch wdn-scroll-watch" data-lerp="opacity" data-lerp-opacity-end="#attribute2" data-lerp-opacity-start="#attribute1" data-opacity-end="0.0" data-opacity-start="1">
             <figure>
                 <img alt="Wheat field" src="samplecontent/unsplash_522af94630a3d_1.jpg">
             </figure>
         </div>
         <div id="opacity-start" style="position:absolute; bottom:55%;"> </div>
         <div id="opacity-end" style="position:absolute; bottom:30%;"> </div>
     </div>

Flipbook

Flipbook properties control a series of images that will display within the band image as the user scrolls the page. By setting different values you can control when and what images will cycle through the band image. A traditional flipbook is a crude form of animation, where you create a bunch of sequential images and flip through them quickly, creating the illusion of motion. While the Flipbook effect is named after this sequential animation, you need not implement it in such a fashion, meaning the photos don't need .

data-lerp="flipbook" Tells the plugin to use the Opacity effect.
data-lerp-flipbook-start="#attribute1" Tells the plugin where to begin the effect.
data-lerp-flipbook-end="#attribute2" Tells the plugin where to end the effect.

The flipbook-start and flipbook-end are set to trigger at specific IDs. These could be existing page IDs, like #header or #maincontent or a custom ID that you place on your page, such as #flipbookstart and #flipbookend. Use a naming convention that helps to easily identify it.

After you've created the wdn-band nest within it a div with the class wdn-scroll-watch, you will also need to add wdn-stretch to that same div, or the images you use won't go fullscreen. Speaking of which, nested in the scroll-watch div, place the images you want to use in individual <figure> tags. Save and test your page. Don't forget your trigger IDs!

      <div class="wdn-band">
            <div class="wdn-stretch wdn-scroll-watch" data-lerp="flipbook" data-lerp-flipbook-start="#attribute1" data-lerp-flipbook-end="#attribute2">

            </div>
        </div>

Locked Aside

Locked Aside properties sets an image as a static, or locked, background image, with an area of scrolling text layered over it, usually with a transparent layer beneath the text. When the effect triggers, the background image will expand to take up the entire screen, and return to normal width when the end effect ID triggers.

data-lerp="locked" Tells the plugin to use the Locked Aside effect.
wdn-scroll Tells the plugin to scroll the content.

Start by creating a div with the classes wdn-stretch, wdn-scroll-watch and locked applied to it and nest it within your wdn-band. Nested in the locked div nest the image you want as your Locked Aside background in a figure tag. Create a new div nested in the wdn-band apply the wdn-grid-set and wdn-scroll classes to it. This is where you will place your scrolling text. In the example we use a half column but you could use nearly any width of column you wanted. Add a float and background color to the wdn-col with a style tag. Add your content (HINT! you will need enough text/content to warrant scrolling or there won't be a visible effect!). Save and revise as needed!

Locked Flipbook Aside

The Locked Flipbook Aside might sound like a mashup of the previous two styles. That's because it is! For this effect you will use a set of images for the image band. When the initial effect trigger is tripped, the first image in the set will expand to fit full screen. As you scroll through the content in the 'aside' box the images will switch to the next image in the set. The final image will return to normal width when the end trigger is tripped.

Follow the steps for setting up a Flipbook found above. Add the class locked to the wdn-scroll-watch div to add the Locked style to the Flipbook. It should look something like this: <div class="wdn-stretch wdn-scroll-watch locked" data-lerp="flipbook" data-lerp-flipbook-start=".locked-lerp-start" data-lerp-flipbook-end=".locked-lerp-end">. To finish the effect create the wdn-grid-set for the scrolling text. Detailed instructions can be found in the Locked Aside section above, but in short, after placing your images for the Flipbook, add a div with wdn-grid-set and wdn-scroll classes applied to it. Add your wdn-col that will hold your content, style it, add your content. Save. Test. Revise.

Somewhere on this page I think it should mention that you need the javascript to initialize the plugin – had to grab it off of one of the demo pages:

<script>

</script>
