Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=ISO-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “android-touch-icon” for attribute “rel” on element “link”: The string “android-touch-icon” is not a registered keyword.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Attribute “viewstatemode” not allowed on element “div” at this point.
The element “input” must not appear as a descendant of the “a” element.
Duplicate attribute “async”.
The “align” attribute on the “img” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “div” 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.
Bad value for attribute “coords” on element “area”: Expected a minus sign or a digit but saw “ ” instead.
Bad value “226, 24, 225, 39, 231, 40, 235, 47, 237, 57, 245, 58, 257, 79, 276, 76, 285, 69, 285, 63, 281, 57, 281, 51, 275, 44, 270, 41, 272, 36, 266, 31, 259, 26, 256, 20, 246, 23, 242, 20, 232, 25” for attribute “coords” on element “area”: Expected a minus sign or a digit but saw “ ” instead.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
