What is the difference between the Style attribute and for example the <i> tag

Question

If I wanted to italicize a line of text I could use e.g <i><p> Gold </p></i>

or alternatively I could use

<p style=" font-style : italic ; " > Gold </p>.

Is there a difference? Maybe in the usage? Or is it just Handy to be able to use both to do the same thing

Answer 1

Both works same no compression.

Answer 2

Diffrence is code simplicity in style than in not using style
