How to echo a colored or formatted text?

Question

How to echo a colored or formatted text like we do in html using <font> tags

Answer 1

<?php
echo "<font size='5' color='red' face='Arial'>П</font>"
?>

Answer 2

<font> element is deprecated in html5: use css instead...

<?php
echo '<span style="font-size:5px; font-family:Arial;">formated text</span>'
?>

... or even better practice to not inline css property but define some rules and target the element ( by use of class and/or id attributes ).
Good practice is also to use the more semantical significant tag available, and use <span> and <div> as default generic else ( respectively for inlined or block type content box ).
