HTML5 Ad

A display ad built as a small web page (HTML, CSS, JavaScript) rather than a static image or the retired Flash format. HTML5 allows animation and interaction within the IAB file weight limits (typically 150 to 200 KB initial load) and is built in tools such as Google Web Designer, Adobe Animate, or a creative management platform.
