First step 1: create file with .html extension. 
When HTML (Hypertext Markup Language) was first introduced in 1994, it was used to create simple websites that were readable and navigable by computers. However, with the advent of the Internet and the World Wide Web in 1995, its uses expanded exponentially. Nowadays, HTML is essential for all websites as it is what holds them together, creating them from flat text into interactive web pages that people can view on their computers or mobile devices.

Although the standard has been around since then, some implementations have fallen behind in terms of technology and security.

## what is responsive navigation bar

Responsive navigation bars are designed to change their size, shape, and style depending on the device they are being viewed on. They can also adapt to any screen size so that your website is accessible to everyone. check [portable shot blasting machine](https://www.shotblastingmachines.in/portable-sand-blasting-machine)

A responsive navigation bar is made up of two parts: a header and a footer. The header displays the logo and branding while the footer displays information such as site links or contact information.
