The syllabus of Information Technology (Arts) at Higher Secondary Level has been revised and implemented in view of the fact that computer is used currently as a tool for various applications, especially in the field of e-Banking, e-Commerce, e-Governance, etc. Higher studies and placements, at present, greatly demand human resources with adequate knowledge in computer applications and information technology. The Information Technology aims to equip students the knowledge, skills and attitudes to become productive employees in the area of computer technology. In this course, you all will gain a perspective to become a successful entrepreneur in Information technology and allied sector. Scope of this textbook also provides you all with the foundation for higher studies. Information technology is one of the most significant growth catalysts for the Indian economy. I am sure after completion of HSC with IT, you will acquire skills and competency to any enter in the upcoming job market. In Class XI, the syllabus focused on the fundamentals of computer, computer network, basics of website designing and some knowledge of database. You all are also familiar with web page designing. The image creation and manipulation tools such as GIMP a bitmap graphic software and Inkscape a professional quality vector graphic software are there. The syllabus of Class XII Information Technology (Arts) is a continuation to that of Class XI. Hence the textbook designed in accordance with the syllabus, begins with some advance features of HTML5. Open source softwares like Kdenlive a free and open-source video editing software and Audacity as a digital audio editor and recording software are introduced. Open Street Map, (OSM) the project that creates and distributes free geographic data for the world is added in the syllabus along with new technologies such as 3D printing, AR, VR. The concepts such as E-commerce and E-Governance will make students aware about the digitalization process. I hope this book will meet all the requirements for stepping to levels of higher education and pave the way to the peak of success. Each unit comprises of simple activities and demonstrations which can be done by you on your own.

The content is developed in view of the fact that it should be useful to the students for their higher studies and they should be able to use computer as a tool. Besides, if somebody wishes a shift towards the IT field in higher education, the syllabus can cater to their needs. Although the field of IT continues to expand rapidly, it is not feasible to expand the size of the curriculum proportionately. As a result, the syllabus has been designed in such a manner to inculcate the current technical knowledge among the students. The textbook on Information Technology (Arts) is developed as per the approaches and methods used in recent era of internet and web. As the curriculum is activity-based, process-oriented and based on constructivism, it demands higher level proficiency and dedication from the part of the teachers for effective teaching. This textbook takes two aspects into consideration - knowledge domain and process domain. The knowledge area of the curriculum of Class XII is a continuation to that of Class XI. The programming aspects to solve complex problems and handle complex data are introduced. Since we are in an era of Internet, a wide coverage is given to the contents required for designing web pages and developing web applications. Audacity software is included as it has features of recording audio from multiple sources, post-processing of all types of audio, trimming and fading in and out. The video editing software Kdenlive is incorporated to create, move, crop and delete video clips, audio clips, text clips and image clips. The concepts such as E-commerce and E-Governance is also included. The knowledge about the same is must for today’s generation. The process domain gives importance to gain the Creative and logical method and develop interest for deeper investigation. The recent technologies in IT such as 3D printing, 5G, AR and VR are included in the syllabus to give the current technological knowledge to the students. While transacting the concepts through activities, it should be ensured that the students are attaining the skills along with learning outcomes. The Textbook IT (Arts) is prepared by a team of practicing teachers under the guidance of a panel of subject experts. All possible efforts have been taken to make the books learner-friendly and interesting. There is no denying the fact that our teachers are resourceful and committed, and hence directions towards the right path can make the transaction of the curriculum most effective and productive. Constructive criticism and creative suggestions for improvement of the book are most welcome.

HTML5 is currently used  Student can design the layout of web because it supports mobile technology. pages using CSS. The major browsers are Google Chrome,  Students can learn to design the MozillaFirefox, Microsoft Edge, Safari, website. Opera and Apple support the features of HTML5.  Student can design the web form with validations. 1.2 Forms in HTML5  Students can learn concept of image In eleventh standard we have studied map and Iframe (inline frame). different controls related to form like text, radio, checkbox, submit, reset, select and  The aim is to give the skills to create textarea. HTML WebPages, using HTML5 These controls are used to collect and CSS. different kinds of user inputs, such as contact details like name, address, single 1.1 Advanced Web Designing or multiple options from group of options, as well as clearing and submitting data We have been introduced to basic etc. terminologies related to creation of web pages. The Hypertext Mark-up Language HTML5 has introduced additional (HTML) is an evolving language, with form controls which can also be used for validation purpose. HTML5 advanced elements HTML5 introduces a number of new input type values for the type attribute of tag. Input type Description Defines a color picker Defines a field for entering a number Defines a field for entering a URL. Defines an image as a submit button. Defines a date picker with the year, month and day Defines a field for an e-mail address 1  Input type Description Defines a month and year control in format is "YYYY-MM" Define a range control. Default range is 0 to 100. Defines a date picker that includes the year, month, day and time. Defines a control for entering a time. Defines a week and year control. Defines a text field for entering a search string like a site search or Google search. Defines a file-select field and a "Browse" button for file uploads. Used to define input fields that should contain a telephone number. Input Restrictions A list of some common input restrictions is given below, few of which can be used for validation purpose. Attribute Description disabled Specifies that an input field should be disabled. max Specifies the maximum value for an input field. min Specifies the minimum value for an input field. pattern Specifies a regular expression to check the input values. read only Specifies that an input field is read only (cannot be changed). This acts as a temporary label showing the purpose of a text field placeholder without requiring a label tag. required Specifies that an input field is required (must be filled out). Specifies whether a form or input field should have autocomplete On autocomplete or Off. Specifies that the input field should automatically get focus when the autofocus page loads. height and Specifies the height and width of an width Specifies that the user is allowed to enter more than one value in the multiple element. This works with input types like email and file. 2 Some other useful attributes used with are- 1. id : This is used to identify the html element uniquely through the document object model. 2. class: It is used to apply CSS style to the individual input element. Examples : Forms in html 5 Name: E-mail: Date of Inception: Office time: Number of years completed(between 1 and 100): Office phone number: Add your homepage: The output is as follows Do it Yourself 1. Use multiple attribute in 2. Use pattern attribute in and see the Output. 1.3 tag The meta tag is a tag in html that describes some aspects of contents of a webpage. The HTML tag is used by search engines to search information 3 that is provided with the webpage. This is empty tag (singular tag) which carries information within its attributes. The tag is placed between the and tags. Metadata will not be displayed on the webpage. Attribute of tag Attribute Values Description Name The value of the name attribute Specifies the Name of the meta- can be related to any of the data like the author, keywords or following- i) Author ii) Description description. iii) Keywords iv) copyright e.g. Content It can have any textual matter related to the name as in eg. i. balbharati. ii. advance web designing. iii. like html5 , learn html5 etc. Charset UTF-8, Big5 Specifies the character encoding e.g used by the document, This is called a character encoding declaration. UTF-8 For Indian characters Big5 – for Chinese characters http-equiv refresh , set-cookie, content-type, Used for http response message expires, headers. e.g. every 5 seconds. The browser sends the cookies for the document 4 Example: meta tag examples element you want to style. It could be Declaration Block : The declaration declarations separated by a semicolon. 1. color : yellow; 2. font-size :11 px; Welcome to HTML5 Each declaration contains a property name and value, separated by a colon. Property : A Property is a type of attribute of HTML element. It could be color, border etc. 1.4 Cascading Style Sheets in HTML5 Value : Values are assigned to CSS CSS stands for Cascading Style properties. In the above example, value Sheets. CSS describes how HTML "yellow" is assigned to color property. elements are to be displayed on screen, Selector{Property1: value1; Property2: paper, or in other media. CSS saves a value2} lot of work. It can control the layout Types of CSS of multiple web pages all at once. CSS allows you to control the look and feel There are three methods of of several pages by changing a single implementing styling information to an source. HTML document. 1. Inline CSS CSS Syntax 2. Embedded stylesheet or Internal  A CSS rule set contains CSS  a selector and 3. External CSS  a declaration block. 1. Inline stylesheet : It uses the style attribute in the HTML start tag. 5  Inline CSS is used to apply CSS on a single line or element. For example : The internal style sheet is applied on this heading. Hello CSS This paragraph will not be affected. 2. Embedded stylesheet or internal CSS : This is used to apply CSS on a single document or page. It can affect all the elements of the page. It The output of above program is as is written inside the style tag within follows- head section of html. For example : h1{color: Red;} CSS Properties Property Use Value Example Color Changes the color of the text Color name h1{color: maroon} Background-color To set the background color Color name body{background- in your webpage color:yellow} Font-weight Used to bold text bold or 100, p{font-weight:300} 200…900 Font-style Used to italicize text Italic, oblique or p{font-style:italic} normal Text-decoration This property is used to add p{text-decoration: 1. strike-through marks 1. line-through underline} 2. underline 2. underline a{text-decoration: 3. overstrike 3. overline none} 4. to remove underlines from 4. none links Text-align This property is use to left, right, center h1{text- control the horizontal or justify align:center} alignment of any block-level text that are paragraphs, tables and other elements Font-family This is used to control the Font name p{font- fonts family:arial} 6  Property Use Value Example Font-size This property allows you to px, in, mm, cm, p{font-size:10px} control the size of the font pt Letter-spacing This helps in controlling the px, in, mm, cm, h1{letter-spacing: horizontal spacing between pt 5pt} characters of text Padding This property is used when Pixel h1{padding:30px} you want to add padding (blank spaces) around the content of an element. Border This property adds a border Solid, double, h1{border:double} to a webpage element groove, ridge, inset, outset, dotted or dashed Background-image To set an image as the url(''X'') body{background- background of your webpage where X is the image: path of image url('background. file jpg')} Background-repeat To set the background image repeat no-repeat background-repeat: to repeat or not repeat background-repeat: no-repeat Margin-Left Sets margin area on the left px,pt,cm etc. h1{margin- side of the element. left;10px} 3. External stylesheet : The external An external style sheet can be written style sheet is generally used when you in any text editor, and must be saved want to make changes on multiple with a.css extension. The external css pages. It facilitates to change the look of the entire web site by changing file should not contain any HTML tags. just one file. It uses the tag on Here is how the "style.css" file looks every page and the tag should like: be put inside the head section. Style.css For example : h1{color:navy;margin-left:20px} The output is as follows This is a heading 7 CSS Id Selector The class name should not start The Id selector selects the id with number. attribute of an HTML element to Let's take an example with a class "intro". select a specific element. An id is always unique within the page so it is unique element. It is written with the hash character(#), followed by the id name..intro{text-align:center;color:blue} This heading is blue and center-aligned. #para1{text-align: center; color: blue} This paragraph is blue and center-aligned. Hello Students The above code results as This paragraph will not be affected. Class Selector for specific element See the output as follows To specify only one specific HTML element should be affected then you should use the element name with class selector. Let's see an example : p.intro {text-align: center;color: blue} CSS Class Selector The class selector selects HTML elements with a specific class attribute. This heading is not It is used with a period character '.' affected (full stop symbol) followed by the class This paragraph is name. The Class selector is used when blue and center-aligned. you want to change a group of elements within your HTML page. 8 The output is as follows h1{ text-align:center;color:blue} h2{ text-align:center;color:blue} p {text-align:center;color:blue} As you can see, you need to define Universal Selector CSS properties for all the elements. It The universal selector is used as can be grouped as- a wildcard character. It selects all the h1,h2,p{ text-align:center;color:blue} elements on the Webpages. Let`s see full code as follows : * { color: green; font-size: 20px;} h1,h2,p{text-align: center; color: blue} This css style will be applied on Entire page.It does not check tag or plain text This css is applied to heading Hello Heading 1 Hello Heading 2 (In smaller it is applied to first font) paragaraph This is a paragraph. Also to second paragraph ! Output : Output : Group Selector The grouping selector is used to select Positioning in CSS all the elements with the same style CSS helps to position the HTML definitions. It is used to minimize the elements. The position property is used code. Commas are used to separate each to set position for an element. The selector in grouping. element can be positioned using the top, Let's see the CSS code without group bottom, left and right properties. selector. 9 Syntax : Output : Selector{position:value;top:value; left:value:bottom:value;right:value} Where values in positions are fixed, absolute, relative and values of top, bottom, left, right are in pixels 3. Relative Positioning : The relative There are four types of positioning in positioning property is used to set the CSS element relative to its normal position. 1. Static Positioning : This is a by- 4. Absolute Positioning : This property default position for HTML elements. sets an element in a specific location It is not affected by the top, bottom, and it is not affected by the flow of left and right properties. the page. This property positions the element at the specified coordinates 2. Fixed Positioning : This property relative to your screen top-left corner. helps to put the text fixed on the For example : browser. The FIXED property forces an element into a fixed position relative to the browser window. The fixed element will not move, even.first{position: relative;top: -10px; when the page is scrolled. right: -10px;} h2{position: absolute; Let`s see the example : left:100px;top:150px} This is heading 1 p.fixed{position: fixed; top: 50px; right: 5px; color: blue} This is heading 2 Output : This is paragraph 1 This is paragraph 2 This is paragraph 3 This is the fix positioned text. 10  In above output the Level 1 headings Balbharati with class=“first"have a relative position 10 pixels above and 10 pixels to the right This text rearranges itself to flow of it’s original position. around the element that is floated right. All level 2 headings will be positioned 100 pixels from the left of the browser window and 150 pixels from the top of Output the browser window. Float Property Float is a CSS property written in CSS file or directly in the style of an element. Display property The float property defines the flow of content. The Display property in CSS defines how the components (div, hyperlink, Following are the types of floating heading, etc) are going to be placed on properties : the web page. It specifies how the element 1. float : left : This keeps the element is displayed. As the name suggests, this float on left side of the container property is used to define the display of 2. float : right : This keeps the element different parts of a web page. float on right side of container Syntax : 3. float : none : This is default property Display : value; i.e. this shows the element as it is.
