You are also not required to indent code (in most languages); please do if you want me to read it though.
Closing optional HTML tags just adds more ambiguity. How many HTMLParagraphElements here, what do you think?
<p>
text1
<p>
text2
</p>
</p>HTML is more content than programming logic, so it shouldn't be indented.
You can also indent with spaces and tabs at the same time, who's judging?
