About CSS - Cascading Style Sheets
CSS, or Cascading Style Sheets, is a specific language that is used to display a document that was originally designed in a markup language. One of the most common uses for CSS is the display of webpages that were originally written in either XHTML or HTML. However, it can be used for a number of other projects, and some of these include documents that were created in XML. As of this writing, CSS is controlled by the W32, or World Wide Web Consortium. CSS has a number of different levels. Each level within CSS is based on the previous level that came before it.
The levels will typically be identified as CSS2, CSS3, and so on. The higher levels will have new features that are not present in the previous levels. Another concept that can be found in CSS is profiles. The profile is a subset of the various levels of the language. Each profile will be designed for a specific device. At this time, there are profiles for printers, portable devices, and tvs. It is important to note that profiles are completely different from media types. CSS is the primary tool that is used by those who read and write web pages. It will play a role in the font, colors, and appearance of the document.
The original program that was used to create the document will be separated from the display that will be made via CSS. Separating these elements are crucially important, because they can allow the content to be accessed more readily, and they can showcase a larger amount of flexibility in the way the document is presented. In addition to this, the difficulties involved with the foundation of the content will be greatly reduced. CSS is powerful because it can allow the a document to be displayed in a wide variety of different styles. Some of these styles may be by voice or print. CSS data can be given in a large number of different ways.
The information for CSS can be offered in external stylesheets, inline styles, and embedded styles. With the external stylesheet, the data will be a separate file which is taken from the original document. With the inline style, the information will be presented on a single element. With the embedded style, various blocks of CSS data will reside within the HTML document. As you can see, there are a number of powerful advantages to using CSS. The display information for one website can be held in one location, and this allows it to be quickly updated. Each user can have a separate style sheet, and this means that people who have vision issues can use a different style sheet than those who do not.
In addition to this, specific style sheets can be used for cell phones, and this allows webpages to be displayed on them. CSS can take the complex code from the original document and greatly simplify it, because there is not need to showcase the original markup. Overall, CSS uses a syntax which is relatively simple.
