qt.io site is "special" it has a bunch of flashy effects like fades, spinning, rotating, moving big web elements.

On desktop this might be "cool", however on low end embedded devices it gives most of the time bad first impression:

• long loading time
• effect makes impression that everting is slow
• scrolling page makes it even worse
• full screen page feels that page is broken, since big image tiles are titled with odd angle

This might not be the best way to promote qtwebengine.
