Know Html

In 1980, physicist Tim Berners-Lee, then a outworker at CERN, planned and prototyped ENQUIRE, a system for CERN researchers to use and go halves papers. In 1989, Berners-Lee wrote a memo propose an Internet-based hypertext system. Berners-Lee individual HTML and write the browser and head waiter software in late 1990. That year, Berners-Lee and CERN data systems engineer Robert Cailliau collaborated on a joint request for funding, but the project was not formally adopted by CERN. In his individual notes from 1990 he listed “some of the many areas in which hypertext is used" and put an encyclopedia first. The first publicly available portrayal of HTML was a document called "HTML Tags", first mentioned on the Internet by Tim Berners-Lee in late 1991. It describe 18 elements comprise the initial, relatively simple intend of HTML. Except for the hyperlink tag, these were strongly influenced by SGMLguid, an in-house Standard Generalized Markup Language (SGML)-based documentation plan at CERN. Eleven of these elements still exist in HTML 4.HTML is a markup language that web browsers use to construe and compose text, images, and other textile into visual or audible web pages. Default characteristics for every item of HTML markup are defined in the browser, and these distinctiveness can be altered or enhanced by the web page designer's additional use of CSS. Many of the text elements are found in the 1988 ISO technical report TR 9537 Techniques for using SGML, which in turn covers the features of early text formatting languages such as that used by the RUNOFF command developed in the early 1960s for the CTSS (Compatible Time-Sharing System) operating system: these formatting guidelines were derivative from the information used by typesetters to manually format documents. However, the SGML concept of generalized markup is based on elements (nested annotated ranges with attributes) rather than merely print effects, with also the separation of construction and markup; HTML has been progressively moved in this direction with CSS.

Know Word press

Word Press users may set up and switch among themes. Themes allow user to modify the look and functionality of a Word Press website and they can be install without varying the content or physical condition of the site. Every Word Press website requires at least one theme to be present and every theme should be intended using Word Press standards with structured PHP, valid HTML and Cascading Style Sheets (CSS). Themes may be straight installed using the Word Press "Appearance" direction tool in the dashboard or theme folders may be uploaded via FTP. The PHP, HTML (Hypertext Markup Language) and CSS code found in themes can be additional to or edited for providing advanced features. Word Press themes are in all-purpose classified into two categories, free themes and best themes. All the free themes are listed in the Word Press theme directory and premium themes should be purchased from marketplaces and personality Word Press developers. Word Press users may also create and develop their own custom themes if they have the contact and skill to do so. If Word Press users do not have themes expansion knowledge then they may download and use free Word Press themes from word press.org.WordPress's plug-in progress allows users to make longer the features and functionality of a website or blog. Word Press has over 40,501 plugs available, each of which offers custom functions and features enabling users to tailor their sites to their specific needs. These customization range from search engine optimization, to patron portals used to display private information to log in users, to content management systems, to pleased displaying features, such as the adding up of widgets and course-plotting bars. But not all available plug-in are always abreast with the upgrades and as a result they may not function properly or may not function at all. Native applications exist for Webs, Android, iOS (phone, iPod Touch, iPod), Windows Phone, and BlackBerry. These applications, designed by Automatic, allow a limited set of options, which include totaling new blog post and pages, commenting, moderating comments, replying to comments in addition to the ability to view the stats.Word Press also features incorporated link management; a search engine–friendly, clean permalink structure; the ability to assign multiple categories to articles; and support for tagging of posts and articles. Automatic filters are also included, providing homogeneous formatting and styling of text in articles (for example, converting regular quotes to smart quotes). Word Press also supports the Trackback and Pingback standards for displaying links to other sites that have themselves linked to a post or an article.

Know Java script

Css is a way sheet language used for recitation the presentation of a document in print in a markup language.Although most often used to set the visual style of web pages and user interfaces written in HTML and XHTML, the language can be applied to any XML document, including plain XML, SVG and XUL, and is applicable to representation in speech, or on other media. Along with HTML and JavaScript, CSS is a cornerstone technology used by most websites to produce visually engaging WebPages, user interfaces for web applications, and user interfaces for many mobile application. CSS is designed primarily to including aspect such as the layout, colors, and fonts. This separation can perk up content accessibility, supply more flexibility and control in the enable the separation of document content from document presentation, measurement of production characteristics, enable multiple HTML pages to share formatting by specify the relevant CSS in a separate .Css file, and reduce complexity and reiteration in the structural content. This separation of formatting and content makes it possible to present the same markup page in unusual styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. It can also be second-hand to at hand the web page differently depending on the screen size or device on which it is woman viewed. Readers can also specify a unlike style sheet, such as a CSS file stored on their own computer, to dominate the one the author has human being. Changes to the graphic design of a article (or hundreds of documents) can be useful quickly and easily, by editing a few lines in the CSS file they use, rather than by shifting markup in the documents. The CSS specification describes a priority scheme to determine which style rules apply if more than one rule match against a particular element. In this so-called cascade, priorities (or weights) are calculated and assigned to rules, so that the results are predictable. The CSS specifications are maintain by the World Wide Web conglomerate (W3C). Internet media type (MIME type) text/css is registered for use with CSS by RFC 2318 (March 1998). The W3C operates a free CSS validation service for CSS documents.

Know about Java script

Microsoft Windows script technology including VBScript and Script were on the loose in 1996. Script, a reverse-engineered implementation of Netscape's JavaScript, was released on July 16, 1996 and was part of Internet Explorer 3, as well as being available server-side in Internet in sequence Server. IE3 also incorporated Microsoft's first hold up for Cascading Style Sheets and various extensions to HTML, but in each case the implementation was noticeably diverse to that found in Netscape Navigator at the time.These differences made it difficult for designers and programmers to make a single website work well in both browsers leading to the use of 'best viewed in Netscape' and 'best viewed in Internet Explorer' logos that characterized these early years of the browser wars. JavaScript began to acquire a standing for being one of the roadblocks to a cross-platform and standards-driven Web. Some developers took on the difficult task of wearisome to make their sites work in both major browsers, but many could not have the funds for the time.[ With the release of Internet Explorer 4, Microsoft introduced the concept of Dynamic HTML, but the differences in language implementations and the different and proprietary Document Object Models remained, and were obstacles to widespread take-up of JavaScript on the Web. In November 1996, Netscape announced that it had submitted JavaScript to Emma International for contemplation as an industry standard, and ensuing work resulted in the standardized version named ECMAScript. In June 1997, Emma worldwide published the first edition of the ECMA-262 specification. In June 1998, some modifications were made to adapt it to the ISO/IEC-16262 standard, and the second edition was on the loose. The third edition of ECMA-262 was available on December 1999. Development of the fourth publication of the ECMAScript standard was never completed. The fifth edition was released in December 2009. The current edition of the ECMAScript standard is 6, released in June 2015. JavaScript has become one of the most all the rage programming languages on the Web. Initially, however, many professional programmers denigrated the language because its objective addressees consisted of Web authors and other such "amateurs", among other reasons. The advent of Ajax returned JavaScript to the spotlight and brought more proficient programming attention. The result was a proliferation of comprehensive frameworks and libraries, superior JavaScript training practices, and increased usage of JavaScript outside Web browsers, as seen by the large number of server-side JavaScript platforms. In January 2009, the playground project was founded with the goal of specifying a universal standard library mainly for JavaScript development outside the browser. With the rise of the single-page function and JavaScript-heavy sites, it is increasingly being used as a assemble target for source-to-source compilers from both dynamic languages and static languages. In fussy, ECMAScript and highly optimized JIT compilers, in tandem with as.js that is friendly to a head-of-time compilers (OAT) like Odin Monkey, have enabled C and C++ programs to be compiled into JavaScript and implement at near-native speeds, causing JavaScript to be considered the "assembly language of the Web”, according to its designer and others.

Introduction php

Php growth began in 1994 when Erasmus Lea doff wrote several Common Gateway boundary program in C which he used to maintain his individual homepage. He extended them to work with web forms and to converse with databases, and called this realization "Personal Home Page/Forms Interpreter" or php could be used to build simple, dynamic web applications. To gather speed bug reporting and improve the code, Lea doff firstly announced the release of php  as "Personal Home Page Tools (PHP Tools) version 1.0" on the Usenet conversation group comp.info-systems. on June 8, 1995. This release already had the basic functionality that php has as of 2013. This incorporated Perl-like variables, form handling, and the ability to embed HTML. The syntax resembled that of Perl but was simpler, more imperfect and less consistent. Early PHP was not intended to be a new indoctrination language, and grew organically, with Lea doff note in retrospect: "I don’t know how to stop it, there was never any intent to write a indoctrination language I have absolutely no idea how to write a indoctrination language, I just kept adding the next commonsense step on the way. A development team began to form and, after months of work and beta testing, officially released php in November 1997.The fact that PHP was not originally calculated but instead was developed organically has led to inconsistent naming of functions and inconsistent ordering of their parameters. In some cases, the function names were chosen to match the lower-level libraries which PHP was "wrapping", while in some very early versions of PHP the length of the function names was used internally as a hash function, so names were chosen to improve the allotment of hash values.
