Line 1, Column 123: Missing xmlns attribute for element html. The value should be: http://www.w3.org/1999/xhtml.…html1/DTD/xhtml1-transitional.dtd"> <html dir="ltr" lang="tr"> <head> <meta ✉
Many Document Types based on XML need a mandatory xmlns="" on the root element. For example, the root element for XHTML will look like:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> - Line 281, Column 3660: end tag for "thead" which is not finished.…100%" align="center"> <thead> </thead> <!-- google_ad_section_start --><tbody ✉
Most likely, you nested tags and closed them in the wrong order. For example <p><em>...</p> is not acceptable, as <em> must be closed before <p>. Acceptable nesting is: <p><em>...</em></p>
Another possibility is that you used an element which requires a child element that you did not include. Hence the parent element is "not finished", not complete. For instance, in HTML the <head> element must contain a <title> child element, lists (ul, ol, dl) require list items (li, or dt, dd), and so on.
