There are four basic principles that should be used whenever you are doing any kind of design work. These principles are especially important in the realm of web design.
Contrast
Using elements such as colors, typefaces, and sized that are different
creates contrast in your layout. Your page design will benefit from this
because contrast produces maximum visibility and emphasis.
Repetition
Consistently using colors and graphic elements on your pages creates a
sense of unity. Repetition can be attractive to your audience and also
makes things easier to read.
Alignment
Keeping everything on your pages visually connected to something else
creates alignment. This design element keeps your eyes from wandering
to items that are placed arbitrarily.
Proximity
Grouping related elements together on pages so they are one cohesive group
is the basis of proximity. This technique keeps your layout organized
and makes it easier to read and navigate through your site.
