HTML markup errors and warnings

Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “text/html;” for attribute “content” on element “meta”: The legacy encoding declaration ended prematurely.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Stray end tag “div”.
The “width” attribute on the “table” element is obsolete. Use CSS instead.
Bad value “/Include/Scripts/Resize/resize.php?src=/Static/Images/UserUpload/1 fase groepenkast.png&w=99&h=148” for attribute “src” on element “img”: Illegal character in query: space is not allowed.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “center” element is obsolete. Use CSS instead.
Warnings:
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
The “language” attribute on the “script” element is obsolete. You can safely omit it.
This document appears to be written in Dutch but the “html” start tag has “lang="en"”. Consider using “lang="nl"” (or variant) instead.
