Mistakes Web Designer
 
Until now, the main mistakes a web design expert (web designer) is the HTML file that he created. Why? Ie web pages that he made did not meet the standards set by W3C. Study conducted by Dagfinn Parnas showed that nearly 99% have a web page on the Internet containing the code - code that is not the standard used. From 2.4 million Web pages he had just found a 0007% valid pages.
 
The main error in a web design page is as follows:
 
1. There is no declaring document (DTD)
 
2. Does not include the required attributes.
 
3. Attribute tags are not standard
 
4. Eliminate the end tag
 
5. No tags early
 
The most popular browser, Internet Explorer, excuse the mistakes above, so if a Web page contains many errors in the code it will still look good in IE.
 
As a result of Error Code
 
The main result of the error code is the accessibility of these Web pages to users. The first result is the browser will reveal abnormalities in the site's appearance, this course will be happen in a browser other than IE, for this you need to check the re-appearance in various browsers.
 
The second result is the difficulty screen reader to read the document because of errors parsing the html tag or attribute is missing. Similar difficulty is when you use a simple text browser.
 
The third result is the difficulty of "indexing" is done by robots Search Engine. As a result the sites you create will be difficult "discovered" by the robots search engines.
 
Error Comes From Where?
 
The main mistake is to use a WYSIWYG editor to create web instantly. In addition to the non-standard tags, another mistake common are empty tag (empty tag).
