What is a website A website, also written as Web site, web site, or simply site, is a set of related web pages served from a single web domain. A website is hosted on at least one web server, accessible via a network such as the Internet or a private local area network through an Internet address known as a Uniform Resource Locator. All publicly accessible websites collectively constitute the World Wide Web.

overview The World Wide Web (WWW) was created in 1990 by CERN physicist Tim Berners-Lee On 30 April 1993, CERN announced that the World Wide Web would be free to use for anyone. Before the introduction of HTML and HTTP, other protocols such as File Transfer Protocol and the gopher protocol were used to retrieve individual files from a server. These protocols offer a simple directory structure which the user navigates and chooses files to download. Documents were most often presented as plain text files without formatting, or were encoded in word processor formats.

What is responsive web design Responsive web design (RWD) is a web design approach aimed at crafting sites to provide an optimal viewing experience—easy reading and navigation with a minimum of resizing, panning, and scrolling— across a wide range of devices (from desktop computer monitors to mobile phones).

History of responsive web design Ethan Marcotte coined the term responsive web design (RWD) in a May 2010 article in A List Apat. He described the theory and practice of responsive web design in his brief 2011 book titledResponsive Web Design.

Benefits of using Responsive Web Design your website needs it to serve the growing number of customers who use devices other than the computer to access the internet. Responsive web design allows for optimal viewing of your website across all devices. Here are the top advantages to be gained out of using responsive web design. With responsive web design you’ll be making your website accessible to people 24/7. A lot of your customers will constantly be on the move. In fact, this is one reason why people are turning towards mobile devices to access the web. If your website is not accessible to this sizable chunk of customers or potential customers, then your business has a lot to lose and your competitors have a lot to gain. Don’t let that happen to your business. Websites meant for mobile devices are usually very Spartan and do not have advanced navigational features, such as in websites for computers. Your customers do not want to waste time in looking for features in a poorly designed mobile website. They’d rather go over to competitor’s website. Responsive web design helps you to prevent such a scenario by making viewing a site from a mobile device almost as efficient a process as viewing the same site from a computer. Search Engine Optimization (SEO) is another great reason to go for responsive web design. In any website, one needs links to help the visitors get to the right part of the website. However, if separate websites were made for each kind of device out there – one for computers and laptops, another for tablets, another for mobiles etc, we’d have a lot of links on our hands. Each such link has to be redirected via the server and will add unnecessary load on the server. Additionally, each such link also needs to be specific to the user agent in order to get the visitors to the right part of the website. This will adversely affect the website speed and increase maintenance hassles. Responsive web design helps us to eliminate this issue by having just one website and just one set of links to handle.website speed
