I love hamburgers, not just the irresistible juicy cheesy ones, but also the three lines hiding the entire navigation in the mobile interface. The hidden options get revealed on a single tap. Furthermore, it allows users to access a preferred item easily instead of following a certain serial order in navigation.
A clever solution that got misused in the desktop web design where hiding the navigation options is not required.
In Parallax Scrolling, the background moves slower than the foreground, creating a 3D effect. It’s a hot favorite among designers to enhance designs and add a subtle depth to the elements, but can be overwhelming if executed by amateurs.
It’s bad for SEO as single page layout with parallax design has only a little content for search engines to crawl.
