The terms “website design” and “website development” are used interchangeably, but you need to know the difference if you plan to get one developed for yourself.
Website design is the technique, art, skill which gives your idea, product, business, causes or anything else a virtual placeholder for end users to access online 24 hours using web browsers. It is the customer-facing part of the website. Web development is the programming part of the website which gives end users to interact with your website, leave contact details, search for products and services, buy, sell, share and many other activities.

Websites can be simple plain vanilla ones such as basic, flash based, parallax, responsive or complex ones such as portals, hortals, vortals, auction sites, ecommerce sites etc. With leaps and bounds in technology design and development are dependent on each other and line of difference remains very thin.
