We can put CSS declarations between <style> tags, right in the web page's head section.

<html>
<head>
<style>p {color: blue;font-size: 14px;}</style>
</head>
<body><p>I need CSS treatment.</p><p>Me too.</p></body>
</html>
]]>

These internal style sheets work if a web page has a unique style that doesn't apply to other web pages.

If your HTML got a bit rusty, how about we meet in the micro-course on HTML and brush up on a few things?
