Do you know ? What is API ?

In computer programming, an application programming interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components. A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer. An API may be for a web-based system, operating system, database system, computer hardware or software library. An API specification can take many forms, but often includes specifications for routines, data structures, object classes, variables or remote calls. POSIX, Windows API and ASPI are examples of different forms of APIs. Documentation for the API is usually provided to facilitate usage.

There’s a big difference between responsive and mobile web design..! 🤔

Most people don’t think about the seemingly magical website conversion that happens when they switch between their smartphone and computer. These are two very different approaches to shifting screen sizes, either mobile design or responsive design.

Mobile design is restrictive. It serves up a separate, and often limited, version of your website that can be used on smartphones and tablets. However, because mobile websites generally provide visitors with the bare basics that the site has to offer, they won’t get to see the full glory of your web design or use it to its full potential.

Responsive design is extremely flexible, allowing websites to resize and reflow their layout based on the visitor’s screen size. This gives visitors a consistent experience from large-screen, high-resolution monitors all the way to the smallest smartphone touchscreens, while also having an experience that is suited to each of those individual devices. Responsive websites will simply adapt to their environment, while maintaining the same stunning images, typefaces, and navigational options.

The complexities of web design are indeed mind-blowing, requiring a high level of updated awareness and attention to detail to create the best website possible. Keep these facts in mind as you move forward with your own web presence!
