All about HTML

Daisy-chain (in the English cascade style sheets), is a language that is used to define the template of a structured document written in HTML or XML (and) by extension XHTML CSS style sheets.
The W3C (World Wide Web Consortium) is responsible for the formulation of the specification of the style sheets that are the standard for browser or user agent. The idea behind the development of CSS is to separate the structure of a document from its presentation. For example, the HTML .
older versions of HTML allowed extra cost attributes in the open label formatting (such as color or font size). However each . When CSS is used,. . Specify the type of information, separately in a style sheet, as must be . Style information may be added as a separate document or in the same HTML document. In the latter, the case could define general types in the title of the document or in any particular tag by using the type attribute. CSS provides three different ways to apply style guidelines to a Web page: an external style sheet, is a style sheet that is stored in a different file to the file, the HTML code of the Web page stores. This is the way to set more efficient because it completely separates the formatting for the HTML page of the basic structure of the page directives: A style sheet that is internal, a stylesheet that is embedded within an HTML document. (Going right within) . ) Is in this way, the advantage of the information of the style of the HTML code itself to separate. You can choose to the embedded style sheet on a page to another (this feature is difficult to perform if you synchronized copies) to kopi ë to save ren. In general, is the only time that a style sheet, it is used internally when you any properties to a Web page in single file é é n want to disclose, for example, if you have something to send the Web page. An (inline) style line is a method for the language of page styles within a tag of HTML directly to include.
This approach is not fully designated. Bed the description of the formatting in the document on the Web page, at the level of code, it becomes a long, tedious and are inelegant way to solve the problem of the programming of the page. This way to work would now and then can be used as the format in a hurry, during the flight must perform.
It is not already structured light or that it should be, but it works.
This is the method used for layout in HTML email are advised. The benefits of CSS (or other style language) to use are: centralized control over the presentation of a Web site fully with what considerably accelerates the same update.
Browsers allow users to their own local stylesheet to specify, on a Web site that will be applied, thus considerably increasing accessibility.
For example, people with visual impairments to form their own style sheet to the size of the text to increase or more connections to emphasize.
A page can have different style sheets according to the display device or, even, at the choice of the user. For example, to be printed, displayed on a mobile device or be read by a speech synthesizer. The HTML document itself is clearer to understand and gets to its size (as long as the style not in line is used) to reduce significantly.
Before CSS was available, the only form of space a page together was the use of lists. Although the technical comfortable and versatile, using an element with special semantics, that the express information in tabular form, only by its effect on the presentation is.
The introduction of CSS has in many cases, replaces the use of lists allowed. However, CSS to not even reached the versatility to allow those lists offered, a layout of a complex page tends to be a difficult task in CSS and the differences between browsers are more difficult the task. It is expected that future developments in CSS3 this decision defici ë deficiency and to CSS to create a more appropriate language pari.
