What is html text formating?

Words in <B>bold</B> stand out more than words in <I>italics</I>,

but words in <B><I>both</I></B> stand out even more.

 

<P ALIGN="LEFT">This text is left aligned.</P>

<P ALIGN="CENTER">This text is centred.</P>

<P ALIGN="RIGHT">This text is right aligned.</P>

 

Finally, there are four other tags which produce various effects: <S> for crossed out text; <SUP> for superscript;<SUB> for subscript; and <U> for underlined text. For example:

<P><S>This text will be crossed out</S> <P>E = MC<SUP>2</SUP> <P>C + O<SUB>2</SUB> --> CO<SUB>2</SUB> <P><U>This is important!</U>

Which renders as:

This text will be crossed out

E = MC²

C + O₂ --> CO₂

This is important!
