HTML markup errors and warnings
(Rescan now...)
Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
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.
Duplicate ID “layout-css”.
Duplicate ID “aday”.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “0"” not allowed on element “img” at this point.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Bad value “” for attribute “border” on element “img”: Only “0” is a permitted zero literal.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “uyari”.
Warnings:
The first occurrence of ID “layout-css” was here.
The first occurrence of ID “aday” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Attribute “0"” is not serializable as XML 1.0.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “uyari” was here.
