Big Drop Inc is the type of web design agency that is always on the lookout for new technology that comes with open source status. Based in Manhattan, New York City, this firm builds responsive websites for local customers in diverse niches. A responsive website has to meet certain criteria that is established by organizations such as the World Wide Web Consortium (W3C). For example, web pages have to be encoded with HTML5 and CSS3 in order to ensure that they are compatible with most web browsers. The W3C gives web developers all over the world some strict guidelines for writing the source code for the back end of websites. Big Drop Inc also gets quite creative with other scripts that are not necessarily regulated by any particular entity. For example, jQuery and PHP scripts can enhance the responsive nature of web pages and apps for mobile or desktop platforms.
