Our new website has just launched, we intend to make all pages on corasystem.com comply with Web Content Accessibility Guidelines 2.0 to the highest possible level. Please bear with us as we work through any issues on the website.
When developing accessible websites we use a combination of automated software checks and manual checks to test for accessibility.
There are several elements of a website that can effect its accessibility, they include, but are not limited to:
- All content images have an alternative description when not available or turned off. Images which are merely for decorating purposes contain a null alternative description to not confuse users using screen readers.
- Tables are only used for what they are for: showing tabular data. The site’s design does not rely on any tables which is a major benefit for screen readers and loading time.
- Tables are written in standard compliant mark-up. They contain a summary and headers are labelled as such to make the data for users with visual disabilities.
- All links make sense if read out of context.
- All colours have high contrasts between foreground and background for a high legibility and people with sight problems.
Adjustable Text Size
- Text size can be adjusted because relative font sizes are used rather than absolute sizes.
- There is an option on the website to increase or decrease font sizes. In addition, most browsers have a menu choice to adjust the font size.
- Large text – Large text is defined as 18 point or 14 point bold or larger. 14 point is typically 18.66px and 18 point is typically 24px.
- Fonts that are 18 point or 14 point bold or larger should have a contrast ratio of 3.00:1 or higher with it’s background.
- Small text – Fonts smaller than 18 point or 14 point bold (typically 18.66px) should have a contrast ratio of 4.50:1 or higher with it’s background (measured out to 2 decimal places).
- Content and presentation are strictly separated. For all visual elements style sheets are used. However, if style sheets are not supported or turned off, the site is still usable to its fullest extent.
- Information is provided about the general layout of the site.
- All fields in a form are labelled correctly and use default, place-holding characters like required by WCAG 1.0.
Logical Tab Order
- A logical tab order is created throughout the website.
Valid and standard conform CSS and XHTML
- All of the coding uses valid CSS and valid XHTML 1.0 Transitional.
- The site can be viewed on various browsers including PDAs and screen-readers. Applets and Scripts
- We passed on the use of applets and scripts wherever possible. Java Script is used but not necessary.
