The “font” element is obsolete. Use CSS instead.

Element “p” not allowed as child of element “font” in this context. (Suppressing further errors from this subtree.)

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Attribute “border” not allowed on element “input” at this point.

Warnings

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
