IAB Flex Ad Testing

This project supplies samples and test helpers for the coming Flexible Ad formats. It is broadly broken into two areas: code you might use as a publisher on your site (src) and sample code that shows some of the IAB test ads hosting within a flex container on sample pages (samples)

Project Structure

The below table highlights the main files of interest. There may be more files in a given directory that are for testing or explanation.

Directory or File	Description
src	Top directory holding SDK and styles
pub-flex-styles.css	CSS classes to define a flex container with current aspect ratios (2017).
slot_definition_techniques.html	Description of a variety of techniques to define flex unit containers on the publisher page
src/js	Fles Ad Testing Javascript code
iab-flex-ad-tester.js	Flex Ad Testing SDK file. Include this on your publisher pages to test or inject flex ad units
src/images	Minimal images that can be used for defining flex containers. This technique has been eclipsed by the padding-top technique for defining flex containers
samples	Top directory holding sample publisher pages and embedded ads for testing
three_column.html	Sample three column layout with sample flex ads inserted
twin_sidebars.html	Sample layout with twin sidebars and sample flex ads inserted
samples/dfp	Sample ads served from Google DFP (Doubleclick for publishers)

Defining Flex Containers with CSS and Markup

The IAB has developed and provided CSS styles and a recommended markup structure for flex ad containers. The provided structure and technique maximizes performance and compatibility by relying on CSS and simple markup instead of Javascript and manually measuring aspect ratios. You can read more about this in the file slot_definition_techniques. This code is offered under the MIT open source license.

Include the file pub-flex-styles.css or incorporate the style classes into your site's main CSS file.

Define the following markup (example is a 4x1 container). This establishes the container. Markup to anchor the ad being served from an ad server should be added at AD INSERTED HERE in the below sample

<link rel="stylesheet" href="//your-cdn.com/src/pub-flex-styles.css">
...
<div class="iab-flexad">
	<div class="iab-flexsizer flex-4x1" ></div>
	<div class="iab-adcontent">
		<!-- AD INSERTED HERE -->
	</div>
</div>

Using the Flex Ad Testing SDK

The IAB Flex Ad Testing SDK allows publishers to easily insert flex ad units into their existing page structure for the purposes of testing. This Javascript include does the (not so) heavy lifting of inserting the needed flex container styles and markup and allowing the user to insert flex containers and ads into their existing sit markup with minimal changes.

Example: Including the Flex Ad Testing SDK

<script src="http://flexads.iabtechlab.net:8080/src/js/iab-flex-ad-tester.js"></script>
<script>
	(function(){
		iab.flexAds.setup();
	})()
</script>

The above code will add the IAB Flex Ad Testing SDK menu to an existing page. This is a floating menu that helps by injecting flex containers and ads into an existing page.
