It very well may be viewed as the local language of any internet browser and is utilized to characterize the construction of each page. The site pages we visit on the Internet consistently are composed utilizing a particular language, called HTML. Created by Tim Berners-Lee toward the start of the 90s related to the World Wide Web, the HTML code (an abbreviation for HyperText Markup Language, which can be deciphered as a marker language for hypertext ) is the “native language” of internet browsers.
It permits to design and show off the text and pictures of each page (counting this one) in a configuration that is not difficult to peruse and deal with. HTML, subsequently, serves to characterize the construction and design of a website page utilizing programming components like labels and properties.
To make website pages, HTML editors can be used both in the WYSIWYG rendition ( what you see is what you get, what you see is what you get) and as a content manager. Notwithstanding, it will be important that whoever makes the page is a talented web developer in this last case. Different HTML codes (for example, shading codes) will be entered physically to structure the page impeccably.
HTML Elements
Every HTML page utilizes HTML components, like labels (encased in sections <..> ) and credits, which progressively request the substance. An HTML component ordinarily comprises four sections:
- An initial tag, at least one quality of the actual part.
- The substance to be shown.
- An end tag.
For instance, a standard HTML component will forever begin with the “HTML head body” labels, where the HTML tag shows that the record contains subtleties of this markup language; head gives essential data about the idea of the paper and what it has; body denotes the actual page: every one of the orders that will be embedded after this label will be shown later by the program.
Other similarly significant HTML labels are, for instance, img (which is utilized to embed a picture into the design of the page) sphere, and textual styles, which are used to organize the text of the page. HTML attributes are used to specify the structure of individual HTML elements further. The best known and most used, for example, is the style attribute, which is used to define the style and layout of the web page.
For example, if you want to use HTML colors to color the background of a web page, the body tag will become “body _style =” background-color: # ff0000;” where # ff0000 represents the red color the hexadecimal HTML code used. HTML attributes are specified following a standard syntax structured like this, starting with the tag with two brackets and ending with the slash “/ tag.” “attribute tag =” value”; content to display”.
Versions Of HTML
Since 1991 the HTML code has changed profoundly to adapt to the evolution of the web. In 1995 the HTML 2.0 standard was released, while in January 1997, the HTML 3.2 release arrived, the first to receive the official status of the W3C ( World Wide Web Consortium ) consortium. The web, however, is evolving at incredible speed, and not even 12 months after the last update, the Consortium releases the HTML 4.0 version.
Even though it’s been over ten years since its adoption, it is still the most used version in creating web pages because the development of new versions has suffered more than a few slowdowns. We started talking about the fifth release of HTML only in 2004, when the W3C Consortium decided to merge the development of HTML 4.0 and XHTML 1.0, both standards recognized by the Consortium, in a single project.
HTML5: The Evolution Of The World Wide Web
In 2004 came the expected evolution of the markup language for creating websites: HTML 5, which has marked a farewell to JavaScript and Flash in recent years. The new standard, which is not new, has left unchanged many of the tags provided by the previous one but simplified the language to use to obtain a code that is easier and faster to write. In particular, HTML5 allows you to create dynamic sites and include multimedia content without the need for JavaScript or Flash.
This means that by designing a web page in HTML5, it is possible to insert audio-videos and natively create games and animations without using additional tools. What benefits is not only the speed of the page, which is, therefore, leaner in its coding and easier to process, and the security? By not implementing other tools in the web page’s code, the exposure to cyber-attacks and exploits of various kinds is reduced.
Among the advantages of HTML5, there is also the backward compatibility with previous versions of the standard, which allows you to correctly view even websites created tens of years ago without having to download dedicated programs. Finally, the use of HTML5 does not stop at web pages because it also allows you to create cloud apps to add to the browser, such as the Google Office suite or other web applications.
Web Pages, Not Just HTML: The DOM
HTML is not the only standard needed for creating web pages and sites as we know them. Another essential element is the DOM, the acronym for Document Object Model, the W3C standard with which HTML, XHTML, and XML documents are represented. The DOM plays a different role than HTML because it defines the logical structure of documents and how they can be accessed and then modified. This implies that the DOM is a real programming API instead of HTML, which is just a markup language.
To fully understand the difference between HTML and DOM, it is necessary to define the one that exists between the server-side and the client-side of the scripting of a web page. If a customized response is produced to each client’s request to the website, you are working on the server-side, i.e., scripts on a web server. Several programming languages, including PHP and Python, are used for scripting. On the other hand, we are on the client-side when you have a lightweight script or an empty HTML skeleton.
We can say that a server-side scripting system generates a complete HTML code directly in the web server, while the client-side returns a partial HTML code, which the client itself must then complete. The filling of the HTML skeleton occurs by modifying the DOM of the page, to which all the elements foreseen in the HTML will be added. This makes the DOM an HTML that is always valid, that is, a template that can always be modified by Javascript and includes hidden elements.
