Hypertext is a text displayed on the computer browser which renders via web for immediate access. Hypertext documents are interconnected by hyperlinks which can be accessed by clicking on the text or hovering over the link.
Hypertext is one of the key underlying concepts of the World Wide Web. All webpages are represented with Hypertext Markup Languages (HTML). HTML is a hypertext markup language which can include a table, image, video, graphics and other presentational content forms with integrated hyperlinks.
What Are Web Servers?
In today’s world, we all know what a computer is and we can all open a web browser which has been installed on a personal computer or laptop. We go to the address bar of the browser and type a URL (for e.g. https://www.google.com).
What does it mean?
When we write this Uniform Resource Locator (URL) in the webpage’s address bar, we are locating or requesting the web server to serve the Google webpage onto the browser screen.
In simple terms, a server is a computer connected to the Internet, waiting for a request from the browser. Each server stores Hypertext files, pictures, audio, video and other types of multimedia files.
When the request has been given from the user, if the URL is correct, then the request will be served back to the browser.
What Does A Web Browser Do?
We already know, when we surf the Web and we click on a hyperlink, we trigger a request to the web server to serve the HTML file on the browser window.
But how does the browser know how to display the page? The browser engine understands and accepts resources such as HTML, XML, images, PDF. The resources get accepted by the rendering engines. Each browser has different engines. Internal browser component main flows in the down below.
When a Hypertext file gets loaded on the browser, it will convert all HTML files to HTML documents. The browser creates a Document Object model. HTML provides content and structure to the browser. The browser must convert each element into its own model so that the browser can understand what HTML it must convey to the end user. Technically, the browser rendering engine will convert each HTML document into DOM nodes called content trees.
As a web developer, when you are creating HTML files to create a web page, you are not performing any manual effort to display your content in the browser screen. Rather, the browser parses it for you when converting each HTML element into content nodes.
Let us write down the syntax and semantics of the HTML code in such format so that the browser will accept your request and render that unto the browser screen.
Skeleton body of HTML file. Let us consider the HTML version is 5.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <body> <header> <h1>Web development</h1> </header> <section> <p>This is paragraph</p> <a href="https://www.google.com">This is a link</a> </section> </body> </html>
Explanation Of The Code
All HTML files are declared with <!DOCTYPE html> and it is not an element or a tag in HTML. It is a standardization of html5 version.
HTML starts with an opening tag <html>. HTML is an element and ends with </html>.
The ‘head’ is a vital part of the HTML element which contains the title of the webpage and meta.
The ‘meta’ is an element introduced in html5 which describes the internal information to the browser. ‘charset’ is this attribute which defines which style of file it provides to the browser.
‘Body’ is a tag and a visible part of an entire HTML document.
The header is a child of the body which writes the heading part of HTML.
h1 is HTML heading which will display. The font size of this h1 content will be larger.
The section is an element which defines content that can be displayed in the webpage.
p is the paragraph element tag which defines the paragraph content for the webpage.
<a href=”http//www.google.com”> </a> is the anchor element which will hyperlink to another webpage.
‘href’ is nothing but hyper reference attribute for the anchor tag which will bind the URL of any webpage.
After we click this link, we are redirected to the Google webpage. In short, it hyperlinks by clicking a link and gives us access to www.google.com.
HyperText Markup Language version 5 and 5.1 are the future of Web Development. A majority of users now access the Internet via mobile devices rather than desktop computers. Hypertext Markup Language is the primary tool to create webpages. Now, for web developers, it’s not only about creating web pages; rather, it is about making the web pages faster, more robust and highly progressive.
HTML5 provides developers all the benefits with new tags and API’s. HTML5 contains good semantics structure and it allows web developers to create webpages with enhanced User Interfaces (UI).
HTML5 creates a new stage in the market with an enhanced set of tags. This makes the webpages a more responsive as the market has evolved owing to to the migration of users to mobile devices from desktop computers.
People want web pages that load faster, where the loading time should ideally be instantaneous. Webpages should provide the user a better User Interface.
There are certain benefits in HTML5 as it allows users to access websites in offline mode. It contains web storage API (application programming interface) facility and provides an online and offline web experience. We can save important data locally using a local storage facility. HTML5 has enhanced connectivity, speeding up and boosting real-time chats, games. The new html5 audio and video tags, have allowed smother integration of audio and video on the Web. HTML5 provides the best animation features that we can use now, with Canvas and SVG (API).
The future of Web Development is maturing every day. According to reports, 65% of developers have chosen HTML5 for major projects. In the near future, a web application will be required to work for most of the mobile platforms if not all. For this and many other reasons, HTML5 is believed to be an important tool in the future of Web Development.
