Good web design has visual weight, is optimized for various devices, and has content that is prioritized for the medium. The most important elements of a web page should have more visual weight to “naturally attract” a visitor’s attention.
Optimization for various types of devices and resolutions plays a fundamental role in modern website design. Web page layouts should be genuinely responsive and not rely on any fixed-size elements. Web designers using fluid grids and flexible images will guarantee that a web page will render well on a variety of devices, windows, and screen sizes.
Good design is making something intelligible and memorable. Great design is making something memorable and meaningful.
