Accessibility
The following accessibility features are present in the Free Bet Calculator:
- All pages adhere to the XHTML 1.1 standard which helps to maximise compatibility and consistency across different browser types.
- Site navigation is simple and consistent.
- The site can be navigated using just the keyboard, by pressing [Tab] and [Shift][Tab] to move forwards and backwards respectively, through each item on a page. An item that has been selected in this way can be activated by pressing [Return].
- A link is provided at the top of each page, which allows users of browsers that do not support stylesheets, to quickly skip down to the site navigation links.
- Browsers that do not support the use of stylesheets and/or images, or that have this support disabled, can still be used to access all of the Free Bet Calculator content and functionality.
- All pages have been designed so that the primary content can be viewed on a screen with a resolution of 800 pixels by 600 pixels, without the need for horizontal scrolling.
- An easy to read font is used for all text.
- Adjustable font sizes allow the size of text to be increased using inbuilt browser functionality.
- Contrasting background and foreground colours are used to highlight active areas of a page; less contrasting background and foreground colours are only used to de-emphasise inactive areas.
Currently, the Free Bet Calculator application requires JavaScript browser support. JavaScript has been employed in an attempt to make the Free Bet Calculator quick and easy to use; primarily by limiting the display of what would otherwise be an overwhelming number of unnecessary items (i.e. the Dead Heat and Joint Favourite options), for bets containing a large number of selections.
The use of JavaScript also enables a significant reduction in the amount of data transferred back to the browser following a bet calculation, which in turn improves responsiveness.
The intention is to extend Free Bet Calculator access to browsers that do not support JavaScript, without affecting the enhanced usability available to JavaScript enabled browsers. Anyone wishing to use the Free Bet Calculator without a JavaScript enabled browser can register their interest by sending an email to feedback@free-bet-calculator.co.uk. You will then be informed as soon as this feature becomes available.
The Free Bet Calculator has been tested with the following browsers on the Microsoft Windows operating system:
- Internet Explorer 5.0, 5.5, 6 and 7.
- Firefox 1.5 and 2.
The Free Bet Calculator has also been tested with Firefox 1.5 on the Linux operating system.
If you have used the Free Bet Calculator on another operating system or browser, any feedback, good or bad, is welcome.
