JavaScript is capable of manipulating the content part(HTML) as well as the presentation part(CSS), and hence, it is the powerful master of the web.

JavaScript frameworks provide simplified structure to complex commands in the form of simple blocks of JavaScript code, thereby making the process of programming easier and faster.

Today the process of software development is primarily composition: breaking down complex problems into smaller problems, and solving the smaller problems which are finally combined to get the complete solution in the form of your application.

HTML is actually not a programming language, but it is a markup language. Markup languages are designed for the definition, presentation, and processing of text.

The HTML content comprises three building blocks

HTML elements: HTML elements are the building blocks of any HTML web page.

HTML Tags: An HTML tag surrounds the content to be displayed and applies a special meaning to it.

: This is an empty tag which introduces a line break.
: This is another empty tag which draws a horizontal line on the screen.

HTML attributes: HTML attributes are special properties attached to the HTML elements to impact their behavior.

The HTML page is like a tree structure with each element forming a node of the tree and different nodes having a parent-child relationship between them starting from the root node (HTML).
