HTML markup errors and warnings
(Rescan now...)
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “center” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
