            <!DOCTYPE html<\/span>><\/span>\r\n<html<\/span> lang<\/span>=\"en\"<\/span>><\/span>\r\n \r\n<head<\/span>><\/span>\r\n    <!--Meta data--><\/span>\r\n    <meta<\/span> charset<\/span>=\"UTF-8\"<\/span>><\/span>\r\n    <meta<\/span> http-equiv<\/span>=\"X-UA-Compatible\"<\/span>\r\n          content<\/span>=\"IE=edge\"<\/span>><\/span>\r\n    <meta<\/span> name<\/span>=\"viewport\"<\/span>\r\n          content<\/span>=\"width=device-width, initial-scale=1.0\"<\/span>><\/span>\r\n \r\n    <!--The description written on title tag\r\n        get appeared as browser tab name--><\/span>\r\n    <title<\/span>><\/span>Geeks For Geeks <\/title<\/span>><\/span>\r\n \r\n    <style<\/span>><\/span>\r\n        h1<\/span> {\r\n            color<\/span>: #006600<\/span>;\r\n            text-align<\/span>: center;\r\nborder<\/span>: 2px<\/span> solid #091418<\/span>;\r\n            background-color<\/span>: yellow;\r\n        }\r\n        .container<\/span> {\r\n            border<\/span>: 2px<\/span> solid #040804<\/span>;\r\n            background-color<\/span>: slategray;\r\n        }\r\n        p<\/span>{\r\n            border<\/span>: 2px<\/span> solid #040804<\/span>;\r\n            background-color<\/span>:  #4089c5<\/span>;\r\n        }\r\n<\/span><\/style<\/span>><\/span>\r\n<\/head<\/span>><\/span>\r\n   \r\n<!-- Whatever content in the body tag\r\n     appears on the webpage --><\/span>\r\n \r\n<body<\/span>><\/span>\r\n    <div<\/span> class<\/span>=\"container\"<\/span> ><\/span>\r\n        <h1<\/span>><\/span>Geeks for Geeks(h1) <\/h1<\/span>><\/span>\r\n         \r\n<p<\/span>><\/span>\r\n             This is a paragraph example of block\r\n             element which occupied whole width (p)\r\n        <\/p<\/span>><\/span>\r\n \r\n    <\/div<\/span>><\/span>\r\n<\/body<\/span>><\/span>\r\n \r\n<\/html<\/span>><\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
            34. What is the difference between block and inline elements?<\/strong><\/p>\n\n\n\n
            Every element in HTML has a default display value which depends upon the element type. Block or inline are the default display value for the most of the elements.<\/p>\n\n\n\n
            • Block Level Elements: A block-level element always starts on a new line and stretches out to the left and right as far as it can.<\/li><\/ul>\n\n\n\n
              Div element: The div element is used as a container for other HTML elements. It has no required attributes. Style, class and id are the commonly used attributes<\/p>\n\n\n\n
              • Inline Elements: An inline element is the opposite of the block-level element. It does not start on a new line and takes up only necessary width.<\/li><\/ul>\n\n\n\n
                • span element: The span element is used as a container for text. It has no required attributes. Style, class and id are the commonly used attributes.<\/li><\/ul>\n\n\n\n
                  35. What is the \u2018class\u2019 attribute in HTML?<\/strong><\/p>\n\n\n\n
                  The class attribute is used to specify the class name for an HTML element. Multiple elements in HTML can have the same class value. Also, it is mainly used to associate the styles written in the stylesheet with the HTML elements.<\/p>\n\n\n\n
                  36. What is the difference between the \u2018id\u2019 attribute and the \u2018class\u2019 attribute of HTML elements?<\/strong><\/p>\n\n\n\n
                  Multiple elements in HTML can have the same class value, whereas a value of id attribute of one element cannot be associated with another HTML element.<\/p>\n\n\n\n
                  37. Define multipart form data?<\/strong><\/p>\n\n\n\n
                  Multipart form data is one of the values of the enctype attribute. It is used to send the file data to the server-side for processing. The other valid values of the enctype attribute are text\/plain and application\/x-www-form-urlencoded.<\/p>\n\n\n\n
                  38. Describe HTML layout structure.<\/strong><\/p>\n\n\n\n
                  Every web page has different components to display the intended content and a specific UI. But still, there are few things which are templated and are globally accepted way to structure the web page, such as:<\/p>\n\n\n\n
                  <header>: Stores the starting information about the web page.<\/p>\n\n\n\n
                  <footer>: Represents the last section of the page.<\/p>\n\n\n\n
                  <nav>: The navigation menu of the HTML page.<\/p>\n\n\n\n
                  <article>: It is a set of information.<\/p>\n\n\n\n
                  <section>: It is used inside the article block to define the basic structure of a page.<\/p>\n\n\n\n
                  <aside>: Sidebar content of the page.<\/p>\n\n\n\n
                  39. How to optimize website assets loading?<\/strong><\/p>\n\n\n\n
                  To optimize website load time we need to optimize its asset loading and for that:<\/p>\n\n\n\n
                  CDN hosting – A CDN or content delivery network is geographically distributed servers to help reduce latency.<\/p>\n\n\n\n
                  File compression – This is a method that helps to reduce the size of an asset to reduce the data transfer<\/p>\n\n\n\n
                  File concatenation – This reduces the number of HTTP calls<\/p>\n\n\n\n
                  Minify scripts – This reduces the overall file size of js and CSS files<\/p>\n\n\n\n
                  Parallel downloads – Hosting assets in multiple subdomains can help to bypass the download limit of 6 assets per domain of all modern browsers. This can be configured but most general users never modify these settings.<\/p>\n\n\n\n
                  Lazy Loading – Instead of loading all the assets at once, the non-critical assets can be loaded on a need basis.<\/p>\n\n\n\n
                  40. What are the various formatting tags in HTML?<\/strong><\/p>\n\n\n\n
                   HTML has various formatting tags:<\/p>\n\n\n\n
                  <b> – makes text bold<\/p>\n\n\n\n
                  <i> – makes text italic<\/p>\n\n\n\n
                  <em> – makes text italic but with added semantics importance<\/p>\n\n\n\n
                  <big> – increases the font size of the text by one unit<\/p>\n\n\n\n
                  <small> – decreases the font size of the text by one unit<\/p>\n\n\n\n
                  <sub> – makes the text a subscript<\/p>\n\n\n\n
                  <sup> – makes the text a superscript<\/p>\n\n\n\n
                  <del> – displays as strike out text<\/p>\n\n\n\n
                  <strong> – marks the text as important<\/p>\n\n\n\n
                  <mark> – highlights the text<\/p>\n\n\n\n
                  <ins> – displays as added text<\/p>\n\n\n\n
                  41. What are the different kinds of Doctypes available?<\/strong><\/p>\n\n\n\n
                  The three kinds of Doctypes which are available:<\/p>\n\n\n\n
                  Strict Doctype<\/p>\n\n\n\n
                  Transitional Doctype<\/p>\n\n\n\n
                  Frameset Doctype<\/p>\n\n\n\n
                  42. Please explain how to indicate the character set being used by a document in HTML?<\/strong><\/p>\n\n\n\n
                  The character set is defined in <meta> tag inside <head> element.<\/p>\n\n\n
                  <meta<\/span> http-equiv<\/span>=\"Content-Type\"<\/span> content<\/span>=\"text\/html; charset=UTF-8\"<\/span>><\/span>\n<meta<\/span> charset<\/span>=\"UTF-8\"<\/span>><\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
                  43. What is the difference between <strong>, <b> tags and <em>, <i> tags?<\/strong><\/p>\n\n\n\n
                  The effect on a normal webpage of the tags <strong>, <b>  and <em>, <i> is the same. <b> and <i> tags stands for bold and italic. These two tags only apply font styling and bold tag <b>, just adds more ink to the text, these tags don’t say anything about the text.<\/p>\n\n\n\n
                  Whereas, <strong> and <em> tags represent that the span of text is of strong importance or more importance and emphatic stress respectively than the rest of the text. These tags have semantic meaning.<\/p>\n\n\n\n
                  44. What is the significance of <head> and <body> tag in HTML?<\/strong><\/p>\n\n\n\n
                  <head> tag provides the information about the document. It should always be enclosed in the <html> tag. This tag contains the metadata about the webpage and the tags which are enclosed by head tag like <link>, <meta>, <style>, <script>, etc. are not displayed on the web page. Also, there can be only 1 <head> tag in the entire Html document and will always be before the <body> tag.<\/p>\n\n\n\n
                  <body> tag defines the body of the HTML document. It should always be enclosed in the <html> tag. All the contents which needs to be displayed on the web page like images, text, audio, video, contents, using elements like <p>, <img>, <audio>, <heading>, <video>, <div>, etc. will always be enclosed by the <body> tag. Also, there can be only 1 body element in an HTML document and will always be after the <head> tag.<\/p>\n\n\n\n
                  45. Can we display a web page inside a web page or Is nesting of webpages possible?<\/strong><\/p>\n\n\n\n
                  Yes, we can display a web page inside another HTML web page. HTML provides a tag <iframe> using which we can achieve this functionality.<\/p>\n\n\n
                  <!DOCTYPE html<\/span>><\/span>    \r\n<html<\/span>><\/span>    \r\n<body<\/span>><\/span>    \r\n<h2<\/span>><\/span>HTML Iframes example<\/h2<\/span>><\/span>    \r\n<p<\/span>><\/span>Use the height and width attributes to specify the size of the iframe:<\/p<\/span>><\/span>    \r\n<iframe<\/span> src<\/span>=\"https:\/\/www.devopsschool.com\/\"<\/span> height<\/span>=\"300\"<\/span> width<\/span>=\"400\"<\/span>><\/span><\/iframe<\/span>><\/span>    \r\n<\/body<\/span>><\/span>    \r\n<\/html<\/span>><\/span>  <\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
                  46. How is Cell Padding different from Cell Spacing?<\/strong><\/p>\n\n\n\n
                  Cell Spacing is the space or gap between two consecutive cells. Whereas, Cell Padding is the space or gap between the text\/ content of the cell and the edge\/ border of the cell. Please refer to the above figure example to find the difference.<\/p>\n\n\n\n
                  47. How can we club two or more rows or columns into a single row or column in an HTML table?<\/strong><\/p>\n\n\n\n
                  HTML provides two table attributes \u201crowspan\u201d and \u201ccolspan\u201d to make a cell span to multiple rows and columns respectively.<\/p>\n\n\n\n
                  48.  Is it possible to change an inline element into a block level element?<\/strong><\/p>\n\n\n\n
                  Yes, it is possible using the \u201cdisplay\u201d property with its value as \u201cblock\u201d, to change the inline element into a block-level element.<\/p>\n\n\n\n
                  49. How many ways you can display HTML elements?<\/strong><\/p>\n\n\n\n
                  • Inline: Using this we can display any block-level element as an inline element. The height and width attribute values of the element will not affect.<\/li>
                  • Block: using this, we can display any inline element as a block-level element.<\/li><\/ul>\n\n\n\n
                    • Inline-block: This property is similar to inline, except by using the display as inline-block, we can actually format the element using height and width values.<\/li>
                    • Flex: It displays the container and element as a flexible structure. It follows flexbox property.<\/li>
                    • Inline-flex: It displays the flex container as an inline element while its content follows the flexbox properties.<\/li>
                    • Grid: It displays the HTML elements as a grid container.<\/li>
                    • None: Using this property we can hide the HTML element.<\/li><\/ul>\n\n\n\n
                      50. When to use scripts in the head and when to use scripts in the body?<\/strong><\/p>\n\n\n\n
                      If the scripts comprise some event-triggered functions or jquery library then we should use them in the head section. If the script inscribes the gratified on the page or is not inside a function then it should be placed inside the body section at the bottom. In short, follow below three points:<\/p>\n\n\n\n
                      • Place library scripts or event scripts in the head section.<\/li>
                      • Place normal scripts that do not write anything on the page, in the head section until there is any performance issue.<\/li>
                      • Place scripts that render something on the web page at the bottom of the body section.<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"
