HTML5 Recommendations

• It’s recommended that additional content such as CSS, JS, images, etc, be politely loaded, including shared libraries.
• At this time, it’s preferred to use internal CSS Style Sheets within the <HEAD> of your HTML code.
• Use CSS for animations where possible.
• To reduce file sizes, please consider using:
• HTML, JS & CSS code minifiers.
• Sprites, SVG or compressing images using ‘Save for Web’.
• Web fonts. Consider only loading the characters that the creative is using.

Backup ‘non-flash’ file (JPG or GIF) must accompany every ad.
