There is no functions in html:
It is only used to create documents for the web browser.
here is an example file of html, and css:
<!DOCTPYE html>
<html>
<head>
<title>There is no function to html</title>
<style>
#heading {
color: red;
}
</style>
</head>
<body>
<h1 id="heading">There are no functions in html</h1>
</body>
</html>
yeah
