An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
A slash was not immediately followed by “>”.
The “center” element is obsolete. Use CSS instead.

End tag “br”.
End tag “center” seen, but there were open elements.
Unclosed element “div”.
Warnings:
The “complementary” role is unnecessary for element “aside”.
