In general terms, aesthetics is an area in philosophy in which practitioners study beauty as it relates to art. Plato first spoke of the pleasure brought onabout by the quality of beauty. Good designs communicate a mood, or a feel that goes beyond the content in the design. 

Design influences everything, and we can find examples of it everywhere we look. We see design in our furniture, electronic equipment, in our food packaging, our transportation, our clothing, our architecture, and our technology. We experience design at every turn. 

Graphic and web designers often learn about the formal principles and elements of design. You can think of the elements of design as the basic components involved with creating any design. 

Color, value, texture, shape, form, space, line and type are eight elements of web design.

In web design,the designer not only consider the meaning and relative importance of the site content, but also to reflect on the user’s experience,and to anticipate visitors’ habits and needs. 

I think all of us are familiar with Google, which is a website that we use almost every day.Its overall design is very simple, but it is most convenient for users to use.
