As more and more people use their smartphone to access the web, it is getting increasingly important to have a website that will work well when viewed on a phone. This can be accomplished by building a responsive website. A responsive website will adjust to display correctly depending on what device it is viewed on. Some factors to consider when building a responsive website includes:
User Experience
Users usually have a different need and expectation when accessing your site form a smartphone. They are looking for fast important information such as contact information, location and services.
Layout
The screen on a phone is obviously much smaller than a computer, and this poses some special problems. While technically most non-responsive website can be displayed on a smartphone, they will likely be almost impossible to use on a small phone screen.
Usability
The way you interface with a site on a smartphone is different from a desktop. There is no mouse or separate keyboard, and certain types of content will not display well on a phone. All this needs to be considered when building an effective responsive website. There are also special functions that are available on a phone, such as a 'click to call' button.
