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.

Set viewport

When designing websites that respond well to many devices, add elements .

This will create a viewport for the page, instructing the browser how to control the size on the page. This is an example of a website that does not use a meta viewport (left) and a website that uses a meta viewport (right).

Images have high feedback

Responsive image or responsive image are images that resize to fit the browser size. There are several ways to create images with this ability.

Use width characteristics

If the CSS width property is set to 100%, the image will shrink and enlarge.

Note that the image may be magnified more than the original size, so use the max-width. feature above all else max-width.

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

Besides changing the size of text and images, the use of Media Query to display websites on multiple devices is also very popular because they help define different ways of displaying on different browser sizes.

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.
