I’m not following any trends, I’m just doing my *own* thing. If somebody says you can’t use rounded corners anymore because they are overused, that type of info hasn’t any value for me. If I’m working on something that I feel is better suited with rounded corners I will use them, trendy or not. Just like with anything else I feel it is ok if it fits the project or when used in moderation. That’s why I never look at web site galleries because they kill inspiration imho.

I’ve noticed designers including more and more texture in their website designs over the past year or so. I remember in the Web 2.0 days designers were revolting over the bright gradients and glossy interfaces with heavy textures, but since then the texture use has definitely become more subdued. Textures in website designs now are very subtle, usually a light noise or grain that just takes away that ‘fake’ digital feel to provide a more realistic tactile impression.
What’s next? We’ve already seen this subtle texture use bringing back retro and vintage styles, so I reckon we’re going to see more designs inspired by old posters and advertisements with effects to replicate basic printing techniques like old-world screenprinting.

It’s no secret that responsive design is the next big thing. As designers explore responsive layouts, techniques like responsive images are gaining traction. In his recent article on A List Apart, Mat Marquis goes into detail about the challenges arising with scalable images. Within the year, I foresee SVG solutions becoming increasingly popular and more widely supported.

Current trends: Responsive Web Design has undeniably been the hottest trend of last year, and still hasn’t faded away from the spotlight. New layout methods too, especially Flexbox, although in my opinion they are not mature yet to be used in production, as they don’t degrade gracefully at all.

What’s next: CSS filter effects, or in other words, SVG filters for HTML, with simpler syntax. Currently they are only supported by WebKit nightlies, but I think that once they propagate to stable versions, they are going to be a very hot trend. They allow us to do things that are currently impossible in plain CSS, such as desaturating, blurring, colorizing and things like that, with super simple syntax that degrades gracefully.
