Web Browsers
The purpose of a web browser (Chrome, Edge, Firefox, Safari) is to read HTML documents and display them correctly.
A browser does not display the HTML tags, but uses them to determine how to display the document:
HTML Page Structure
Below is a visualization of an HTML page structure:
<html>
<head>

</html><h1>This is a heading</h1>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
Note: Only the content inside the <body> section (the white area above) will be displayed in a browser.
