Jquery:
jQuery is a lightweight, "write less, do more", JavaScript library.
The purpose of jQuery is to make it much easier to use JavaScript on your website.
jQuery takes a lot of common tasks that require many lines of JavaScript code to accomplish, and wraps them into methods
that you can call with a single line of code.
HTML:
"Hypertext" refers to the hyperlinks that an HTML page may contain.
"Markup language" refers to the way tags are used to define the page layout and elements within the page.
Below is an example of HTML used to define a basic webpage with a title and a single paragraph of text

Hi,

You can build a site even without using Jquery. Jquery has some functions makes you to ease your DOM jobs.

for example, to add a span to div you have to write in javscript,

var dateSpan = document.createElement('span')
var div = document.createElement('div');
div.appendChild(dateSpan);

But in jQuery, you can do simething like in a single line,

$('
').append('').

And,

Responsiveness in HTML5 is that the sites should fit various devices. Responsive web design gives web creators to make layouts that respond/adjust to any screen size[desktop, mobile, tablet]
