Part 3  Implementation

3 

Use of style sheets for different platforms. We introduced 

Cascading Style Sheets 

(CSS)

 in Chapter 11 as a mechanism for enabling different style elements such as typogra-

phy and layout to be controlled across an entire site or section of site.

  Managers need to check with designers that the CSS will be designed to be flexible for 

making minor changes to presentation (for example in the case of a re-branding) and that 

it supports different platforms such as mobile access or print output.

4 

Accessibility support. We saw in the section on  user-  centred design in Chapter 11 that 

web accessibility

 is about allowing all users of a website to interact with it regardless 

of disabilities they may have or the web browser or platform they are using to access the 

site. The level of accessibility support provided (Level A, AA and AAA) should be defined 

before implementation and then validated as part of implementation.
