HTML markup errors and warnings
(Rescan now...)
Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
Duplicate attribute “rel”.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “modulepreload”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Duplicate ID “cityId”.
CSS: “bottom”: only “0” can be a “unit”. You must put a unit after your number.
Duplicate ID “videoSource”.
No space between attributes.
Attribute “;” not allowed on element “iframe” at this point.
Bad value “1” for attribute “allowfullscreen” on element “iframe”.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
The first occurrence of ID “cityId” was here.
The first occurrence of ID “videoSource” was here.
Attribute “;” is not serializable as XML 1.0.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
