Introduction
A Layout Engine is known by many names like a Rendering Engine or a Web Browser Engine. It is a software component that reads the marked up content along with its formatting information. Based on this, it displays the content (formatted) on the screen.
The marked up content includes the HTML files, XML files, image files among others and the formatting information is given by the CSS files. So, it is safe to say that the web engine paints the content area that is to be displayed on a monitor or printed by a printer.
There are different ways in which a layout engine may operate. Sometimes, engines wait to receive all the data before it renders the page. It may also begin rendering the page before it receives all the data. This can lead to the pages changing as further data is received.
For eg. Sometimes, the web page gives a flash of unformatted content before the entire page is loaded. This is caused because rendering had been already started before the formatting information (CSS files) was received by the browser.
Basic Working:
The engine takes the URL and a set of window content area rectangle. URL provides the document to fill in the content. The document includes everything that a web page has like links, forms, plug-ins etc. So, as we see the layout engine does bulk of the work.
Rest of the features like menu bars etc. are provided by the host application itself.
Commonly, a web engine is embedded in the web browsers. Other applications that require displaying of web content also have web engine in them like on-line help systems or e-mail clients.
Layout Engines of some popular Web Browsers:
• Google Chrome – Blink
• Mozilla Firefox – Gecko
• Internet Explorer – Trident
• Safari – WebK...

For the above code, the parse tree will look something like this-
But the job of the rendering engine is not limited till here. The styling of the pages is also handled by the same rendering engine. The following figure gives a good idea of how the CSS (style sheets) are handled by the engine.
Conclusion
Introduction of a new rendering engine like Blink in place of the efficient WebKit was bound to bring a lot of changes in the way web is perceived and worked with in the world. It has significant implications. Still, it is believed that presence of multiple layout (rendering) engines will only be beneficial to the web and will encourage us to further innovate in this field.
Over the long run, this will definitely lead to a more stable web with fewer bugs and more reliability.
The Wireless Markup Language (WML) is used to create pages that can be delivered using WAP. WML is a language that allows the text portions of Web pages to be presented on cellular telephones and personal digital assistants (PDAs) via wireless access. WML is part of the Wireless Application Protocol (WAP) that is being proposed by several vendors to standards bodies. The Wireless Application Protocol works on top of standard data link protocols, such as Global System for Mobile communication, code-division multiple access, and Time Division Multiple Access, and provides a complete set of network communication programs comparable to and supportive of the Internet set of

If our website has more than 100 pages and we get more than 10k visitors per month, we can imagine the complexity of interaction that will happen in our website.
Unlike traditional Web browsers, WAP browsers were designed to run within the memory and bandwidth constraints of the phone. Third-party WAP sites served up pages written in a markup language called Wireless Markup Language (WML). These pages were then displayed on the phone’s WAP browser. Users navigated as they would on the Web, but the pages were much simpler in design. Handset manufacturers could write one WAP browser to ship with the handset and rely on developers to come up with the content users wanted.
With a lot of card layout choices to the user of the website, it is very important to make the web page stand out from the crowd. The modern user has high expectations to see a good design in the web and he can be very unforgiving if the website does not immediately impress. In these day, you should understand user needs to make a nice user experience. For example, if you want to make perfect shopping experience the developers must understand what their user will respond to and what the message you want your website to
Yet, CSS is very useful in many scenarios, more and more healthcare delivery systems are converting to computers, ranging from client information, to keep track of finances.
Some GUI can be designed using single panel with a single simple layout. Some GUI need to be broken down into smaller panels which have to be added to an outer panel. Each smaller panel can have its own layout.
Now is the technology era for in the world, many people live with technologies in their daily life. In general, technology meant knowledge of tools improve a pre-existing solution to a problem. There were so many habits of using technologies, like using computer to do documentation works, using social network to chat with friend in other country, until now using mobile devices to view web sites. Growth in mobile devices and smartphones had eased many people access Web pages. Normally, we use the computer or desktop to open a browser and visit to some websites. The content of websites is same when you use personal computer and desktop to visits it, caused by the size of screen is almost same. To build a more user friendly website that allow user to view the exactly same content of the Web pages regardless of the device’s screen size, a web pages with responsive web design is introduced. Responsive web design is ways to design web pages that work consistently across different screen size, platform, and user interface by using the same codebase (Pilon, 2013). The issues we always focus is the elements, pros, and cons. Hence, this report will discuss about the main components, advantages, and disadvantages of responsive web design.
While 2D animation is hand drawn with subtle changes from its previous one then put in a sequences to creates the illusion of movement, 3D animation uses computers to help create the sense of motion. The procedure of 3D generation falls into three main sections: layout and animation, modeling and rendering. First, a layout artist would begin to break 2D storyboards into 3D shots. They refer to the production designs and models to build location scenes and important props, to position the characters and camera angles and movements they would like inserted into the game. The layout artist are responsible for staging all the shots, plotting the actions taken within each scene, and also making sure the voiceovers and musical soundtrack mingle with the images correctly. It is up to the layout artists to determine how long the scene shall be. After finishing drawing the layouts,the animators begin to start modeling the scene. Modeling is the phase that describes the procedure of generating 3D objects within a certain scene. In modeling, animators first start off with a simple object, called a primitive, and begin to mold it to a shape where it can be improved and detailed. The most common modeling used is box modeling, which they
Nowadays, backgrounds are one of the basic features that can finalise that how interesting the website is (Cronin, 2009). Most of the company using colour as the important element to create the advertisement in order to influence customers’ attention and decision making (Moore and Stammerjohan and Coulter, 2005). Therefore, Doublewoot should change the black and white colour to the colour that is more attractive such as red. According to Belluck (2009), the researchers from University of British Columbia has conducted the tests with 600 people that red colour did better on tests of memory and attention to an element such as memorizing words.sides that, a responsive web company must have a benefit which is readable in the text. Therefore, customers who are using the hand-held devices will no need to pinch and zoom in order to read it (Franz, 2014). According to Boyarski, Neuwirth, Forlizzi, and Regli (1998) has examined that when Times New Roman, Georgia, and Verdana fonts comparing in desktop screens, Georgia was suggestively perceived is the easiest font and more readable than Times New Roman. Hence, Doublewoot should consult and change their font type to Georgia and the font’s size should also change to bigger in order to make customers easier and faster to read it. In addition, the homepage of Doublewoot should put their feature image and also the latest
Internet Explorer, Chrome, Netscape, and Safari, these are a few examples of some of the web browsers that are used throughout the world. These web browsers have become even more common as the years have gone by. People use them in their everyday life to accomplish tasks that they need to get done. The beginning of this profitable and popular invention all started back in 1990.
Content management system is a procedural system that determines how work flows in any given work environment. With reference to the web environment, content management system may be limited to the creation, control, storage and deployment of individual contents on a given web page. Content management system is differentiated from static pages through a number of ways. Ultimately, whereas content management system should enable a manipulative approach towards the use of the web pages in question, static pages give web users no manipulative option of altering the content of the page. Rather, users act as passive beneficiaries who receive the information on the web pages just as they have been stored. This means that given a number of users receiving information from a single server, all users will at any given time receive the same information. Even though the internet has today come to be a great transformation that depends on the principles of content management system in a dynamic way, Eldridge (2001) notes that the internet used to consist solely of HTML or static web pages, that is, web pages that are not changed before being displayed in a web browser.
Web design is the method of making websites. It encompasses many different aspects, together with web page layout, content production, and graphic style. Whereas the terms internet design and internet development are typically used interchangeably, internet design is technically a set of the broader class of internet development. It is formed by using a language called HTML which contains the satisfied content and the Meta data of individual page and they also provide CSS for the web page which will appear in the browser.
When you log onto the Internet using Netscape, Microsoft Internet Explorer, or some other browser, you are viewing documents on the World Wide Web. The current foundation on which the WWW functions is the programming language called HTML. It is HTML and other programming embedded within HTML that make possible Hypertext.
