The Scroll Indicator

Custom scroll position indicators come in many forms: variations on the traditional vertical scrollbar, horizontal elements at the top or bottom of the page, and other unique styles. Custom scroll indicators can offer the benefit of visual consistency across operating systems and provide needed feedback when the native scrollbar gets hijacked by infinite scroll.

A web developer is a programmer who specializes in, or is specifically engaged in, the development of World Wide Web applications, or applications that are run over HTTP from a web server to a web browser. Web developers are found working in various types of organizations, including large corporations and governments, small and medium - sized companies, or alone as freelancers. Some web developers work for one organization as a permanent full-time employee, while others may work as independent consultants, or as contractors for an employment agency. Web developers typically handle both server-side and front-end logic. This usually involves implementing all the visual elements that users see and use in the web application, as well as all the web services and APIs that are necessary to power the front-end. Salaries vary depending on the type of development work, location, and level of seniority.

Modern web applications often contain three or more tiers, and depending on the size of the team a developer works on, he or she may specialize in one or more of these tiers - or may take a more interdisciplinary role. A web developer is usually classified as a Front-end web development or a Back-End Web Developer. For example, in a two-person team, one developer may focus on the technologies sent to the client such as HTML, JavaScript, CSS, ReactJs or AngularJS and on the server-side frameworks (such as Perl, Python, Ruby, PHP, Java, ASP, ASP.NET, Node.js) used to deliver content and scripts to the client. Meanwhile, the other developer might focus on the interaction between server-side frameworks, the web server, and a database system. Further, depending on the size of their organization, the aforementioned developers might work closely with a content creator/copy writer, marketing adviser, user experience designer, web designer, web producer, project manager, software architect, or database administrator - or they may be responsible for such tasks as web design and project management themselves. There are no formal educational or licensure requirements to become a web developer. However, many colleges and trade schools offer coursework in web development. There are also many tutorials and articles, which teach web development, freely available on the web - for example: Basic JavaScript Even though there are no formal educational requirements, dealing with web developing projects requires those who wish to be referred to as web developers to have advanced knowledge/skills. Web development is the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing a simple single static page of plain text to complex web-based internet applications (web apps), electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web engineering, web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development. Among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding. Web development may use content management systems (CMS) to make content changes easier and available with basic technical skills. For larger organizations and businesses, web development teams can consist of hundreds of people (web developers) and follow standard methods like Agile methodologies while developing websites. Smaller organizations may only require a single permanent or contracting developer, or secondary assignment to related job positions such as a graphic designer or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department. There are three kinds of web developer specialization: front-end developer, back-end developer, and full-stack developer. Front-end developers responsible for behavior and visuals that run in the user browser, while back-end developers deal with the servers. Since the commercialization of the web, web development has been a growing industry.
