Overview

HTML5 Single Expandable base format is built using a single page architecture, with both banner and panel markup contained in a single html file.

Although the HTML5 Single Expandable is not a Custom Format (base format), we encourage the use of curated templates for all "HTML5 Single Expandable ad executions" as they are consistently maintained and tested, and have recently been updated with new capabilities, such as support for running in both mobile web and MRAID in-APP environments.

The templates can be customized and extended to include additional userActionCounter's, automaticEvent Counters, or any of our HTML5 features from features block.

The ad starts as a collapsed panel and can then be either expanded or clicked through to another site.

On the expanded panel, the user can either click the UserAction button, or close the ad and return it to the collapsed state. Clicking the UserAction button records a custom interaction and is hence being tracked in reports. Some expandable templates contain a video element, which is pre-set to track video interactions.

While the HTML5 Single Expandable can be customized to any size, industry standard banner dimensions are made available within the template, to cover a  wide array of browsers, screens and devices.

See below for complete list of available templates:

Customizing HTML5 Single Expandable in HTML

All of the HTML5 Single Expandable functionalities are coded within the template files. At a minimum, the only change you will need to make is to the image ".jpg" and video ".mp4" assets, and their respective styles and markup. 

To update the layout and design of a template, open the index.html and style.css files in a text editor.

Resize Banner:
To customize the dimensions of a main banner update the style.css file to match your new size, and generate a default image for the ad.Upon ad setup on the platform, the dimensions of the default image will be used to set the size for the banner.

Resize expansion:
To resize the expansion, you would need to edit both css as well as EB.initExpansionParams() methods arguments. You will find this method invocation in the index.html usually around line 15.
All you need to do is update the values of the arguments so that they fit the size of your expanded panel.

E.g.
if(0)EB.initExpansionParams(xPosition, yPosition, width, height);
When populated it looks like this:
if(0)EB.initExpansionParams(140, 0, 300, 600);

Line 15 of our template's index.html filee:
<script>if(0)EB.initExpansionParams(140, 0, 300, 600);</script>


Authoring tools and 3rd party JS libraries:
If you are developing ads with non-sizmek authoring tools or 3rd party libraries, please use sizmek hosted versions of dependencies listed on this page: Shared Libraries

For guides on building sizmek base formats with Animate CC, Hype or Google web designer, please visit 3rd party authoring tools page.

Features and Dynamic Creative:
Additional features can be added to all adkit based templates, please see this page for a full list of available features.

You can make some of your ads elements(Video, Image, HTML or String) Dynamic (DCO ready) by following the guide on this page.

Below are explanations of the variables and functions used in the template.

Variables

Variable Name

Description

bannerDiv, panelDiv, expandButton, clickthroughButton, userActionButton, video

Global variable(s) used to select DOM elements.

Add/Edit/Remove these variable(s) as you modify elements in index.html.

sdkData, adId, rnd, uid, isMRAID, useCustomClose

These variables store values that are necessary for the ad to run properly once uploaded to the platform.

Please do NOT make any change to these variables.

autoPlayVideo

Set this value to true if you wish the video auto played as soon as the panel expand. You can modify this variable from scripts/settings.js. (This variable only available for the template that come with video)

useDefaultCloseButtonInMRAID

Set this value to true if you wish to use MRAID default close button instead of the custom close button from template when panel expand. You can modify this variable from scripts/settings.js.
Functions

These functions will be chain-triggered when the window is loaded and adkit API is ready - initiated by checkIfAdKitReady function invoking initializeCreative.

Function Name

Description

checkIfAdKitReady

Check to see if the adKit is ready and then proceed to initialize creative.

initializeCreative

Initialize the creative.

initializeGlobalVariables

This is where we initialize the global variables for HTML elements.

initializeCloseButton

This is where we initialize the close button, depending on the serving environment and the variable useDefaultCloseButtonInMRAID, we show/hide our custom close button and/or notify the MRAID API if it needs to hide the default SDK (MRAID) close button.

initializeVideoTracking

This function initializes video tracking by creating a new instance of EBG Video Module.

addEventListeners

This is where we add all the event listeners. In the template, we have added the click event for click through and user action counter, as well as expand / collapse buttons.

registerInteraction

If you're adding dynamic user interactions, make explicit calls to them here, but never call this function. The platform will read from this function to register possible interactions.
if this function is invoked, it will track all of the interactions defined inside it, distorting the metrics.

handleExpandButtonClick

Click event handler function for the expand button.
It also contains auto play video functionality for video templates.

handleCloseButtonClick

Click event handler function for the close button.

handleUserActionButtonClick

Click event handler for user action button.

handleClickthroughButtonClick

Click handler for the click through button.

pauseVideo

The function that pauses the video.
