According to San Diego Web Design, responsive web design is what is becoming the standard for building a site that automatically adjusts to every environment. For instance, if the site is opened on a narrow browser, the design and text reshapes themselves to fit. The same goes for a wide browser, a small one or a large one. The old style rigid designs worked just fine for a desktop environment where designers could predict possible screen sizes in advance, but with more people viewing websites on mobile devices such as phones, notebooks or tablets, the structure of the site must be adjustable to every possibility. The only way to do that is with a mobile web design that is smart enough to understand the limitations of the device and flexible enough to meet every requirement.
