The Standards of the languages use you
In the planning of a situated Internet, three various levels can be followed qualitative standards dictate you to you of the w3c with various degrees of severità:
You will be able a lot easy to verify your situated one cliccando on it with according to button of the mouse and choosing “View source” (you see source) and watching if in the first lines of the code the term “Frameset” is at least present, “Transitional” or best still “Strict”.
This does not guarantee the aderimento to the qualitative standards you, because we must also verify that that same code has been respected (sees “validazioni”). In order to verify the correctness of the written code, we on hand have instruments automati us of validazione, puttinges on hand of the W3C through the Markup Validation Service, to situated Validator.w3.org in order to validate HTML, and to situated Jigsaw.w3.org in order to validate the css.
Tried directly and automatically the validazione of this situated one cliccando on icone “Validatori W3C” on the menù to the left of the situated one.
These are turn out to you, respective Xhtml and Css:
You know the levels of Standard W3C: Frameset, Transitional, Strict
Levels of Standard:
0) No level of qualitative standard respected to you.
1) Level of standard is Frameset, that it is also most permissive, since chip ax I use it of various tag obsolete and still allows of suddividerte the window in frame (sottofinestre), therefore it is destined to disappear from the web.
2) a higher level than qualitative standard is Transitional, that it comes mainly advised in the situated restructure of a already existing one, than does not follow puts into effect it them qualitative standards you, even if however, chip ax I use it of some tag deprecati.
3) the highest level than qualitative standard (that from used me), is Strict, than all the situated ones of new generation would have to follow, it are puntiglioso and strict, it does not admit no type of tag deprecato and no lack of respect of the rules of the w3c, demands one total separation of the contents from the style, making to already obtain a code of for himself optimized and without some type of error, that is a clean code.
Example of Code that respects standards W3C Xhtml Strict:
! DOCTYPE HTML PUBLIC “- //W3C//DTD XHTML 1,0 Strict//EN”
“http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”
HTML xmlns= " http://www.w3.org/1999/xhtml " lang= " it " xml: lang= " it "
Same test on this situated one
Used languages in order to join to the qualitative standards you W3C
In the realization of a situated Internet, it is advised and sometimes tax to follow of the specific rules, in order to achieve the qualitative standards stilati you from the W3C.
The World Wide Web Consortium (W3C) creates the Web standards. Its scope is to carry the Web to its maximum upgrades them.
To the http://www.w3c.it/w3cin7punti.html.potete address to find again a sunto of it objects and the strategic principles to you of the W3C.
Therefore it is right that the customer knows that every code or language, has of the own rules, that they allow not to commit errors neither of sintassi of the same code neither of the rules that would compromise the duration and situated conformity of web the same one.
Not to follow these standards facilitates, tantissimo, the job of the webmaster, but to discapito of situated the same one, that it will turn out to be full of errors and for this obsolete one, without the possibility to be projected towards the future of the web.
I explain because: Not writing a Php code, HTML, css or “CLEANED UP” Javascript, they can be obtained also situated beautiful and winning it is of diagram that of contents, indeed in order better to say is the much easiest one to obtain turns out to you soddifacenti shortly time, using “visual” programs, the so-called the WYSIWYG that are able to realize a situated one in little hours, acting in visual way completely and creating in automatic rifle the code source. And even if the job of this webmaster can seem apparently winning, does not believe of having between the hands situated web professional and a long-lasting one, it will be only a likeable vertina not completely works them, and with to the shoulders pessimo a preparation.
These types of situated facts today also from principianti, not posseggono no type of ottimizazione, and could be visualize solo to you from an user river basin, much narrow one, in more could be do not index from the more important search engines to you like google or more worse still, once it indexes to you to disappear more from the database of the search engines after some month or.
The w3c it recommends xhtml (obtained from the contemporary I use in the programming of the situated one of HTML and css, instead with the added one of the Javascript we obtain dhtml that it will give the possibility to create and to use dynamic styles, dynamic contents, positioning and animation on the elements, filters and transitions, access facilitated to the DOM (Document Object Model) and other anchor.
It will be enough to write a code “cleaned up” on a simple notebook and browser any, in order to create and to test a situated one web.
Languages Standards used in this situated one
The job has been realized in XHTML 1,0 with DTD validated Strict and CSS 2,0 with the instruments automati us of the W3C.
For the generation of the code they are uses the following programs you:
HTML-kit for code HTML and implementazione of Javascript
Top-style for code CSS
Pixiesetup in order to know the esadecimali colors of the situated one originates them.
Bitmap to Icon 3,5 for the visualized creation of the favicon from the browser in the bars of search and the preferred ones.
And other programs or services on-linens for the quality of the situated one, the correctness of the link, the validazioni of the codes.
