However, the souls of the internet are websites, which create a pattern to make different things work according to the need and our demand. According to the internet live stats, there are over 1.8 billion websites that are live on the internet. These sites are the medium of businesses that can provide increased traffic, good leads, and a high conversion rate.

If you are a developer or an owner of a website then there should be a desire to improve the quality of your site. For doing so, you have to keep yourself ahead with the proper strategy and web development trends. So, here we are with the top ten web development trends of 2021 that will bring a new level of user experience and boom the web development industry.   

1. Progressive Web App (PWA) 

Apps have become part of our life. It makes our task less complicated by providing direct access in a click and its advanced UI makes things sorted and displayed in a more understandable way.

PWA is a cost-effective solution as compared to native apps because creating a native application is costly. The page loading speed of PWA is higher than an app. Additionally, PWA is available offline or in the slow internet connection and it doesn’t take much space in the device. 

Considering such a scenario, few companies have redesigned their mobile sites in a more optimized way so that if users don’t want to install the apps, he/she can go for the website. It means an app-like function without downloading it. 

It has a high conversion rate and the users have options for both apps and sites. Very rare Web Development Agencies provide the option of building PWAs.

2. Dark Theme UI 

For a long time, white backgrounds have ruled the website's graphics. Now there is a huge shift towards a darker background. In 2020, the dark theme UI was the top trend and it will continue to be the one in 2021.

It is fact that a dark theme extends battery life as well as reduces eye strain by minimizing luminance emitted by the device, which improves the visual ergonomics and user experience. With that, it looks more aesthetic than the normal theme.

Dark theme UI is available for many software as well as devices and old operating systems have been upgraded for dark theme compatibility. Moreover, brands are focusing on this web development trend to modernize their digital presence.
