Basic Html — Part 2 MCQs with Explanations

It provides fallback for IE8.

HTML5 Shiv is a JavaScript workaround, invented by Sjoerd Visscher, to enable styling of HTML5 elements in versions of Internet Explorer prior to version 9, which do not allow unknown elements to be styled without JavaScript.

All steps are required.

An old strategy was to look at the property navigator.userAgent to detect the browser’s user agent and code based on the pertinent cases.

A custom plug-in uses code that you write and attach to a load test or a Web performance test.

Modernizr is an open source JavaScript library that allows support for different levels of experiences based on the capabilities of each browser using a simple feature detection model.

Modernizr.testStyles() allows you to add custom styles to the document and test an element afterwards. An element with the id of “modernizr” is injected into the page.

Modernizr, in spite of its name, does not actually add missing functionalities to browsers save for the HTML5 tags styling support.

Since Modernizr is a JavaScript object with methods, we can use Modernizr.geolocation to test whether geolocation is supported.

Modernizr.load is optional in your build, but if you are loading polyfills, there’s a good chance it can save you some bandwidth and boost performance a bit.

Modernizr is a JavaScript library that detects which HTML5 and CSS3 features your visitor’s browser supports.

Meta tags store information about the web page—known as metadata that is not necessarily visible to end users (unless you reveal the page source code).

Metadata is data (information) about data. The meta tag provides metadata about the HTML document. Metadata will not be displayed on the page, but will be machine parsable.

Valid values for the “CONTENT” attribute are: “INDEX”, “NOINDEX”, “FOLLOW”, “NOFOLLOW”.

The charset is used to provide the character support.

The noindex value of an HTML robots meta tag requests that automated Internet bots avoid indexing a web page.

All other options are supported in HTML5 except option a.

nofollow is a value that can be assigned to the rel attribute of an HTML a element to instruct some search engines that a hyperlink should not influence the link target’s ranking in the search engine’s index.

The name attribute specifies a name for the information/value of the content attribute.

noarchive helps block search indexing with meta tags.

The metadata can be used by browsers (how to display content or reload page), search engines (keywords), or other web services.

The Microdata spec provides a standardized syntax for additional semantic markup to your web pages to enhance the machine readability of your web pages.

The microdata model consists of groups of name-value pairs known as items. Each group is known as an item. Each item can have item types, a global identifier (if the vocabulary specified by the item types support global identifiers for items), and a list of name-value pairs.

An element with the itemscope attribute specified creates a new item, a group of name-value pairs.

The answer is self explanatory.

For date- and time-related data, the time element and its datetime attribute can be used.

The global identifier of an item is the value of its element’s itemid attribute, if it has one, resolved relative to the element on which the attribute is specified. If the itemid attribute is missing or if resolving it fails, it is said to have no global identifier.

When an HTML document is loaded into a web browser, it becomes a document object.

If the element is a data element, the value is the value of the element’s value attribute, if it has one, or the empty string otherwise.

When called, the method must return a live NodeList object containing all the elements in the document, in tree order, that are each top-level microdata items whose types include all the types specified in the method’s argument, having obtained the types by splitting the string on spaces.

Microdata allows the user to create “custom” elements (sort of), to give a specific meaning to them.

To create a favicon, we can use any graphic editor program in the market such as Adobe Photoshop or Fireworks.

Most of these icons are beautifully designed, and after Apple introduced a new meta tag named apple-touch-icon you can now display website icons on the iOS home screen when you bookmark a site.

A favicon also known as a shortcut icon, Web site icon, tab icon or bookmark icon, is a file containing one or more small icons, associated with a particular website or web page.

The syntax is <link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />

There are two possible reasons for this: a simple mistake in the SVG file, or a misconfigured server.

The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web (abbreviated WWW or W3).

In 2003, the .ico format was registered with the Internet Assigned Numbers Authority (IANA) under the MIME type image/vnd.microsoft.icon

The favicon is supposed to be a set of 16×16, 32×32 and 48×48 pictures in ICO format.

It was used in Internet Explorer’s favorites (bookmarks) and next to the URL in the address bar if the page was bookmarked.
