Fixit – Viewport meta tag

Fixit – Image Maps

Best practice dictates that all style related information should be contained in CSS files and not be included in amongst markup...

Fixit – Inline Styles

Fixit – Empty Image

This test determines if your page has any empty image tags (image tags with no 'src' attribute or an empty 'src' attribute). Leaving image tags empty require processing that is ultimately wasted. When image tags need to be dynamically created this should happen with JavaScript programming...
