What doesn't the validator like?

Question

HTML

Hello!
I checked my landing page ( spkuralgidro.pe.hu ) with a validator ( https://validator.w3.org) for errors, and it gave me 10 errors. But what is hidden behind them, I can’t figure it out ...
I ask you to explain to me exactly what to edit. And what the validator did not like, but if possible, explain in a "for those who are in the tank" principle.

Answer 1

Bad value img/favicon/favicon(2).ico for attribute href on element link

Links should not contain spaces. Replace with %20 (rawurlencode and urlencode functions in php).
The child element of a UL tag can only be LI and nothing else.
Obviously, the php code does not work, namely, the variables are not interpreted as intended.
The fourth mistake is a consequence of the third.
Fifth, sixth and seventh - superfluous closing DIV tags
Eighth - the BR tag is written incorrectly (the slash is not needed at all, or put it at the end)
Here I think it's obvious - you need to add a space before the attribute name
It's also pretty clear - the alt attribute is not allowed on the I tag (maybe you meant to put the title="") attribute
