what does trailing solidus not allowed mean in html

Question

Hello everyone, Im facing a strange sort of problem : in the code down bellow next to the <p> in a different terminal Im warned that " trailing soldus not allowed".
The code still works but I would like to know what does this mean if sometime in the future I find this warning again.
Thank you all in advance.

Answer 1

You have a typo here:
<p> Za koga je ovaj raspored<p/>
The paragraph closing tag slash should be before the 'p'

Answer 2

This is strange too:
<h1 align="center" RASPORED CASOVA III3 > </h1>
The text should be between opening and closing tags, not inside opening tag.

Answer 3
