Figure 4 Recommended Fix
When the developer or the Website Manager clicks the link, it will display the code that must be changed in the webpage to overcome the accessibility issue.

Developing Web contents involves shaping and making many choices involving technical, aesthetic, and usability concerns. With the expanding technical options for communication on the World Wide Web, it is tempted to focus only on issues such as hypertext markup language (HTML) syntax, page layout, or the latest and flashiest technologies. However, there needs to be a broader approach in order to articulate the information content that is to be conveyed. There is also a need to pay attention to the characteristics and qualities of the Website as a medium for communication so that there are not merely duplicate practices intended for paper and other media.

It is Baderman’s business objective that the website is accessible though all hardware devices, it could be a laptop, cell phones, PDAa, iPhone, or Blackberry, as long as it has access to internet, it should be able to browser Baderman’s website.
