Design website running on multiple devices (responsive web design) in HTML

Responsive Web Design - What is a responsive web design?

Responsive Web Design just uses HTML and CSS to automatically resize, hide, minimize, enlarge a website to make it look better on any device (desktop, tablet, phone). A website should look nice and fit on every device.

Use the max-width property

If you use the max-width and set 100% properties, the image will also shrink when needed but never zoom in to the original size.

Images vary according to the width of the browser

Death in HTML allows to use different images with different browser window sizes.

Text size is highly responsive

Text size can be set in units of 'vw', meaning 'viewport width' (viewport width). Then the text size will display according to the browser window size.

Viewport is the size of the browser window. 1vw = 1% viewport width. If the viewport is 50cm wide, 1vw is 0.5cm.

Media Query

High-responsive websites look normal on computer screens but will be smaller when viewed on mobile devices. There are many CSS frameworks that make it easy to apply this to your site like w3.css or Bootstrap. Bootstrap uses HTML, CSS and jQuery to bring visibility into multiple devices for the page.

This is an example of a website that uses Bootstrap to display on multiple devices.
