Errors:

The element “button” must not appear as a descendant of the “a” element.
Attribute “content” not allowed on element “span” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
