Usability and Accessibility
It is important to have a site viewable to all people as it stops alienating potential trade. Also, discriminating against people with disabilities is illegal under the Disability and Equality Acts 2010.
The Web Contract Accessibility guideline is a set of rules and recommendations for websites to encompass disabilities, both physical and mental. Tesco.com has scored AA for it’s efforts to aid everyone. For lower resolution screens blank spaces have been left either side so the site appears all on the same screen. For the visually impaired this allows them increase font size but still see the whole page. The colour scheme has also been designed so all the text appears clearly for colour blind people.

Under viewing options in "My Account" are 5 options to reformat the site for disabilities, including removing Javascript so only the essentials remaining and underlining hyperlinks for the visually impaired. Also, a link at the bottom of the page gives instructions on how to change font size, a summary of the page design and how to edit options. All of this is great, but arguably too hidden for someone with impaired vision.
The site has been very well coded and appears perfectly, on Internet Explorer, Firefox, Opera & Google Chrome, which make up the vast majority of internet usage.
Javascript is used for the adverts but the site runs fine without it and it's usage is mostly cosmetic.
