Micro-interactions
Micro-interactions are the functional, interactive details of a product. When they are well designed they enhance the overall user experience. Micro-interactions are created to surprise the user with tiny enticing moments that are inviting and stimulate a feeling of well being.

Every time you complete a small action on a website or app and there is a specific response to it, this is a micro-interaction. When you refresh a Twitter page and hear a beep, that’s a micro-interaction. Or when you check notification Facebook, the red icon displaying your message count is—you guessed it— a micro-interaction waiting to be clicked.

Chatbots
Chatbots have been an up-and-coming digital release for a while now but will finally move into the spotlight in 2019. This is mostly due to the efficient advancements in AI (artificial intelligence) and machine learning, making them more intelligent and efficient.

Even more video content
You don’t need an explainer video to tell you that video content for the web is nothing new. Video not only diversifies your web page but also caters to an on-the-go audience who don’t have the time to scan and read through text-heavy content.

Minimalism
Optimise only the necessities and cut the extras. The fewer elements on your website, the less your audience will have to think. Plus, it’s aesthetically pleasing to the eye when web space is well balanced and not cramped. Nobody wants to visit a circus site- unless it’s a minimalist one.

Thumb-friendly navigation
With mobile browsing having firmly overtaken desktop, web design is becoming increasingly “thumb-friendly”. Josh Clark wrote a book Designing for Touch, in which he investigates how users hold their mobile phones and how their movements, particularly those of the thumb, should be processed in the web design process. As time goes on, users will encounter increasingly efficient navigation tailored to the thumb and space awareness optimised for mobile aspect ratios.
