Website Accessibility means the website accessible to all the users in the web including visitors with disability. Many website owners know that their website is available in the internet for visitors to access information but possibly may not know whether their website is easily accessible and even be unaware about Disability Discrimination Act (DDA).

According to Disability Discrimination Act (DDA), all the business should make their services accessible to disabled users. There is also a section in DDA which addresses that if a business offers an online service, even the information is on a single page, then the business is responsible for making an effort to make this information accessible to disabled users.

All new websites that are designed and developed should now follow the W3C (World Wide Web Consortium) and Web Content Accessibility Guidelines (WCAG) against which the accessibility of the website is measured. But when the website is found isn't complaint, then anybody can sue you legally, if they want to.

By following these guidelines, you enhance the professional look of your website, provide access to visitors who previously had not no choice, thus increasing your business prospects and finally not to forget, your business is legal.

Some basic Guidelines to increase the accessibility of the visitors

Validate HTML and CSS: To check if the HTML and CSS used is valid, W3C validator can be used. It is necessary that websites are checked as the validator automatically tells you about any errors and accessibility issues in the web pages.

Image and alternative text: For browsers which don't support images, alternative text can be used to explain what the image is about as the user will only see the text.

Resize font text: Most of the internet browsers use Internet explorer to search for information. If the size of the text can be increased by choosing the font size to the largest then it means that your website is accessible to visitors.

Use of Java script: Websites are not easily accessible when java script is disabled. Mostly people have the java script support switched off, if that's the case then make sure that you use the Java script sensibly and unnoticeably.

Check for the following,

1. Website is accessible without the use of a mouse

2. Website has a Sitemap

3. Website has link text relevant to the content (blind users use tabbing while browsing websites from one link to the other)

For better managing your custom design website, there are two types of Content Management Systems that you can choose from: the paid CMS and the open source CMS that you can have for free.

There isn't necessarily any best CMS in the online world today, there are only popular Content Management Systems. Here are some of them:

• Drupal

Drupal would seem to be one of the more advanced open source CMS available for download today. Being open source, thousands of people contribute to its development, and you will find no trouble at all finding a web programmer who knows Drupal, or finding a community of programmers who can troubleshoot your Drupal CMS just in case.

• MamboServer

Mambo is another popular open source CMS that is free for downloading and extremely easy to set up. Its main edge is that its system is scalable and you can actually incorporate it into the whole spectrum of custom web site design - from the really simple sites to the large company-owned sites. You can use Mambo to manage your advertisements or syndicate your content, among other things.

• Open CMS

• Joomla!

• Typo3

Typo 3 is another of those open source systems, although it is designed more for enterprise-level applications like corporate intranet. It addresses issues like branding, version control and maintaining templates in an application.

In choosing which content management system to incorporate to your website, regardless if it's free or open source, one of the key things to keep consider are your custom web design needs, and nothing else.

Like a lot of web developers, I'm not always that disciplined when it comes to the file naming convention I use and I sometimes end up with a situation whereby I have some files that are in lowercase, some that begin with a capital, and some that are a bit of a mixture.

One web site I maintain contains about 2000 web pages and has about 20,000 hyperlinks. As you can imagine, I had one of those sinking feelings when I was told that in order to migrate the web site to a new content management system, all the file names and hyperlinks would need to be changed to lowercase.

Whenever I am presented with a problem like this, my instinct is always to write a Perl script using one or more regular expressions to solve the problem. This particular situation was no exception.

Change a string to lowercase

The following regular expression changes all the characters in a string to lowercase. The first part of the regular expression finds a hyperlink, and the second part converts the string. (Just in case this article is not displayed correctly, there should be a single backslash in front of the 'L$1').

Change a filename to lowercase

Likewise, changing a filename itself is very simple. The following two lines perform the task quite nicely:

(Again, there should be a single backslash in front of the 'L$name'.)
