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”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
No space between attributes.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “”.
Element “input” is missing required attribute “alt”.
The “center” element is obsolete.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.
Malformed byte sequence: “a3”.
Bad value “calendar.php?
do=getinfo&e=436” for attribute “href” on element “a”: Tab, new line or carriage return found.
Bad value “calendar.php?
do=getinfo&e=437” for attribute “href” on element “a”: Tab, new line or carriage return found.
Bad value “calendar.php?
do=getinfo&e=434” for attribute “href” on element “a”: Tab, new line or carriage return found.
Element “option” without attribute “label” must not be empty.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The first occurrence of ID “” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
