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...

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.

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.
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.

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.
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
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
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.
As state, there exist two types of website design layouts: fixed layout and fluid layout.
Web Design is the process of creating, making, and developing websites. It includes many different features such as webpage layout, webpage content, and also graphic designs. In general web design and web development work together, but the term web design is an actual category of web development. The main way of creating websites is building it from scratch using HTML language; which stands for Hypertext markup language. Web designers build websites using HTML tags that define the content of each page. The layout of the webpage and the appearance of all the elements will be built by using CSS; which stands for Cascading Style sheets. Therefore, all of the websites are being of combination of HTML and CSS files to define of how the page going to appear to the client or user. Many web designers prefer to build a web page starting from scratch by typing HTML and CSS codes, and others they prefer using a software for building and designing these webpages. Some of these soft wares to build and design websites are Dream Weaver which is mostly being used on MAC operating system or WordPress and Joomla which makes it easier for the web designer to design the webpage using the templates that these software already have listed, when the designer choose which template to use the software will automatically build the HTML and CSS files to create that template which also saves time and energy of writing those codes. In the following we going to point out the basics of web designing by using HTML and CSS files and show the steps to create HTML template, heading tags, HTML lists, create paragraphs and break tags, create CSS file, CSS rules, Font sizes, color, style, and adding images, hyperlinks, and CSS layouts.
