I think the web design is changed according to the business. For example if the web design is going to promote a product, it should be designed with graphical animations which will attract the customers. So in that case, the tech should be used to reduce the loading time.

In simpler or rich web development, all are based on the new technology which will solve and give a good presentation about the business.

thanks
