How to Design a Website
Graphic design contains underlying principles that govern the most important aspects of great design. These principles create the acronym C.R.A.P. which stands for contrast, repetition, alignment, and proximity. The well-balanced combination of these principles tends to create design which most people would consider visually pleasing.
To say a design is CRAP is quite the compliment (we suggest not trying this with your designer). The original term was coined by writer Robin Williams in his book “The Non-Designers Design Book” written in 1994. Here is an online pdf version of the book: https://diegopiovesan.files.wordpress.com/2010/07/livro_-_the_non-designers_desi.pdf
Creating a great design is more science that one might think. There are quite a few fundamental principles behind the scenes guiding and directing a designer to achieve great results. By simply following the four basic principles of CRAP (contrast, repetition, alignment, proximity) you’ll be well on your way to aesthetically pleasing design.
