- General entity "type" not defined and no default entity
- Reference to entity "type" for which no system identifier could be generated

Now you can re-run the validation check. Your Entrecard is now XHTML Valid!

CSS3: Changing the face of modern day web designing
In the modern era of regular web development, CSS or Cascading Style Sheets are style sheet languages used for describing presentations of documents that are written in different markup languages. The simplest applications of these style sheets are seen in style websites, which are written in XHTML or HTML. This language is also applied for almost all XML documents including XUL and SVG.
CSS3 is the latest style sheet format, which is in a continuous developing stage. It is perfect for the evolving specifications of XHTML and has been continuously under modularization for the same. You find numerous areas where CSS3 has made its mark. It is amongst the most powerful and comfortable tool for any user. Let us discuss some important advantages of CSS3 that has led to its popularity.

The HTML structure was tough for managing, as markups required repetition for every heading while applying them. This made the presentation and maintenance more complex.
However with CSS3 concept, presentations got separated from the structure. In this case, style sheets defined presentational characteristics whereas the document structures were defined in separate heading. Separation of structure and presentation concept can help users for maintaining their web page in an easier, comfortable and efficient manner. Henceforth, it helps in developing the systems on each module basis. Thus, it provides a more flexible system.

It provides users with a feature of auto-scrolling. Your texts are wrapped in such a manner that they become more user-friendly and simultaneously simpler for reading. All these text features are carried out without making shorter lines or words. Again, everything can be embedded in one page only. Henceforth, it makes an economical and comfortable stay for you on the web world.
Handling Flexibility
