Web Site Redesign There are several advantages in having a web site that conforms to web standards . A valid web site allows for broader accessibility , easier code maintenance , and sustainability of the web site despite the volatile development of web-based technologies . However , redesigning an existing web site to comply to standards requires a lot of work , time , and money . Although it is the cost-effective approach of maintaining a web site , checking the validity of the web pages for compliance with standards such as HTML , CSS , or web accessibility guidelines exacts an almost insurmountable task especially for a web site [banner_entry_middle]

with thousands of documents . However , there are several tools and guidelines readily available to remedy the problem . The aim of this is to describe the suggested steps that will help make an existing web site standards-compliant

Validity of the code According to Jeffery Zeldman , author of “Designing with Web Standards ” web standards refers to web authoring using XHTML and XML as structural language , CSS as presentation langauge , W3C DOM as object models and ECMAscript as scripting language among others . Redesigning a web site that complies to web standards entails checking the validity of the code based on these language tools . The Markup Validator , available at W3C , can be used for this purpose . The tool checks for the correctness of a web document line by line against the declared DOCTYPE and returns a list of errors with the corresponding line number where those errors occur . However , this requires that the should have the correct DOCTYPE to inform the validator which version of (X )HTML is being used . Checking the correctness of the DOCTYPE is the primary component of redesigning standards-compliant web pages since the Markup Validator cannot validate the s without it and so it must appear at the very top of each web page (Weakley , 2004

Compatibility and Accessibility After identifying the invalid markups , a decision have to be made on the degree of compliance to be followed . Although strict compliance is ideally the target , it also has several disadvantages like imperfect browser support for CSS which will likely make sites look plain and unattractive in old browsers or some scripts may not work at all in old mainstream broswers . Some layout schemes are also easier using HTML tables that are difficult to achieve using CSS layout without reworking the entire design (Weakley , 2004 . Zeldman suggested two approaches : transitional forward compatibility and strict forward compatibility . The strict forward compatibility approach is suggested for sites whose target audience are thought to have standards-compliant browsers . Although the low percentage of visitors with noncompliant will still be able to view the content , branding and behavior delivery won ‘t be as successful compared with newer broswers and devices . Zeldman list the ingredients of achieving strict forward compatibility which includes full separation of structure from presentation and behavior , use of valid CSS for layout while HTML tables are used solely for tabular data , use valid XHTML 1 .0 for markup , and an emphasis on… [banner_entry_footer]
