Description
The HTML element <style> is used to define document-level style rules, which apply only to the specific document.
- A document can contain any number of 
<style>elements. - It must appear only within the 
<head>element of a document. 
Using the <style> element is good while experimenting with CSS styles, but it has disadvantages. So, the best way to add styles to a document is by linking external style sheets.
The below table summarizes its usage.
