Errors:

End tag “div” seen, but there were open elements.
Unclosed element “ul”.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “yo,” not allowed on element “img” at this point.
Attribute “matías""” not allowed on element “img” at this point.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Attribute “yo,” is not serializable as XML 1.0.
Attribute “matías""” is not serializable as XML 1.0.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
