The “center” element is obsolete.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

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “350"” for attribute “height” on element “iframe”: Expected a digit but saw “"” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.

Warnings:

The “complementary” role is unnecessary for element “aside”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
