Spiegel Design Group is a Los Angeles based website design firm that follows a simple philosophy for completing projects on time. Clean coding with HTML5 and CSS3 is used to build up the foundation of websites. Once the back end work is laid out, front end components are completed with the integration of custom layouts and graphics. Responsive web design also defines the work of Spiegel Design Group. This group builds websites that invite mobile phone and tablet users along with desktop computer lovers. A single domain name is essentially split into two types of versions. Visitors have the chance to select between a desktop or mobile edition of a website. Enterprise level solutions by Spiegel Design Group include eCommerce development with the help of open source software. Shopping carts can be integrated along with safe payment processing systems. Content management systems are also part of commercial website development services.
