HOW DOES HTML WORK?
HTML documents are files that end with a
.html or .htm extension.You can view then using
any web browser (such as Google Chrome,
Safari, or Mozilla Firefox).
The browser reads the HTML file and renders its
content so that internet users can view it.

BASIC HTML DOCUMENT
In its simplest form, following is an example of an HTML
document −
<!DOCTYPE html>
<html>
<head>
<title>This is document title</title>
</head>
<body>
<h1>This is a heading</h1>
Document content goes here.....

</body>
</html>

THE MOST USED HTMLTAGS
HTML tags have two main types: block-level and inline tags.
Block-level elements take up the full available space and always
start a new line in the document. Headings and paragraphs are a
great example of block tags.
Inline elements only take up as much space as they need and
don’t start a new line on the page.They usually serve to format
the inner contents of block-level elements. Links and
emphasized strings are good examples of inline tags.

BLOCK-LEVELTAGS
The three block level tags every HTML document needs to
contain are <html>, <head>, and <body>.
The <html></html> tag is the highest level element that
encloses every HTML page.
The <head></head> tag holds meta information such as the
page’s title and charset.
Finally, the <body></body> tag encloses all the content that
appears on the page.

INLINETAGS
Many inline tags are used to format text. For example,
a tag would render an element in bold,
whereas tags would show it in italics.
Hyperlinks are also inline elements that require <a></a> tags
and href attributes to indicate the link’s destination:
<a href="https://example.com/">Click me!</a>
Images are inline elements too.You can add one using <img>
without any closing tag. But you will also need to use
the src attribute to specify the image path, for example:
<img src="/images/example.jpg" alt="Example image">

PROS OF HTML
 A widely used language with a lot of resources
and a huge community behind.
 Runs natively in every web browser.
 Comes with a flat learning curve.
 Open-source and completely free.
 Clean and consistent markup.
 The official web standards are maintained by
the WorldWide Web Consortium (W3C).
 Easily integrable with backend languages such
as PHP and Node.js.

CONS OF HTML
Mostly used for static web pages. For dynamic functionality, you
may need to use JavaScript or a backend language such as PHP.
It does not allow the user to implement logic. As a result, all web
pages need to be created separately, even if they use the same
elements, e.g. headers and footers.
Some browsers adopt new features slowly.
Browser behavior is sometimes hard to predict (e.g. older
browsers don’t always render newer tags).
