CSS Semantics
Semantics The semantics of the css in the css implies a right, but rather use the name korektnoe classes. And also use the classes only when necessary. Use css classes to the case when there is no the tag css (X) HTML. Thoughtful, semantically korektno named classes and ID can help set up (X) HTML document for future change and the ability to store data in XML, which can be configured differently. Do not call object (id or class), so what it looks like or where it is used. Examples of class names and ID, which are not semantic: YellowText Blue14pxArial FloatRight LeftColumn MiddleColumn RightSideSpace Use of these names is meaningless, because who would not rule styles the site the future can change the styles described in this class that privedetk absurdity. For example: The developer for the text defined a class of yellow YellowText, and in the future when a site redesign, the text color changed from yellow to blue, resulting in we have a class with a certain YellowText blue.
That in itself is absurd. Therefore, when choosing the name class should not be guided by certain styles within a class, and class assignment.

If every paragraph on the page will have the same style, it is not needed for each section, add a class with a description of the style enough to register for the entire section on the page. The main conclusions of this article: Classes and IDs (ID) should be used only when there is a need. Name classes and IDs (ID) should describe the functionality rather than style uses an identifier (ID) in those cases when it is necessary to define a unique style for a page, and the class – when you need a class ispolvat several times on a page.
