In PHP, what are the considerations when using outdated HTML elements like <font> for displaying messages to users?

Using outdated HTML elements like <font> can lead to non-standard and less maintainable code. It is recommended to use CSS for styling instead. To display messages to users, you can use inline styles or classes for styling text.

&lt;?php
$message = &quot;This is a message to the user.&quot;;
echo &quot;&lt;p style=&#039;color: blue; font-size: 18px;&#039;&gt;$message&lt;/p&gt;&quot;;
?&gt;
