Presence on the user’s home screen, which is essentially the most valuable digital real estate, puts your logo front-and-center and your site one click away. Presence on the user’s home screen, which is essentially the most valuable digital real estate, puts your logo front-and-center and your site just one click away.

It has similar concepts to Angular and React, and is relatively simple to use in rendering and coding, especially for new developers. A progressive web app is created with the app shell model with few page refreshes, and it has an entirely native app-like look. According to Statista, there are currently about 3.5 billion smartphone users worldwide who use different devices with varying connection speeds and ever-changing conditions.

Press F12 to open the developer panel in Chrome and click on the audits tab to open Lighthouse. Style.cssI’ve styled the body to fill the entire browser viewport to facilitate centering the content.


A structure like this makes implementing navigation tricky because the user can resize the window or change the orientation of the device.
