The following accessibility features are present in the Free Bet Calculator:-
- All pages adhere to the HTML5 standard, using polyfills where necessary to help maximise compatibility and consistency across different browser types.
- A responsive design allows the website to adapt to a wide variety of devices and screen sizes.
- All content can be viewed on a screen with a width of 320 pixels or more, without the need for horizontal scrolling.
- An easy to read font is used for all text.
- Contrasting colours are used to make content easier to read.
- The pinch zoom feature is enabled for touch-screen devices.
- User-interface controls with large surface areas are used, in order to improve the ease of click and touch activation.
- 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].
- Numerous WAI-ARIA directives have been included, to make user interface controls and dynamic content more accessible to anyone using assistive technologies.
- 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.
The Free Bet Calculator requires JavaScript browser support, which has been employed to make the website quick and easy to use. Amongst other things, it is used to validate user input, control the visibility of what would be an overwhelming number of options if displayed all at once, and manage the process of calculating bets.
The Free Bet Calculator has been tested using the latest available browser on each of the operating systems listed below. Older versions of Internet Explorer and Firefox have also been tested on Microsoft Windows, ensuring the site is still accessible to users of older computers, as long as they are running Windows XP (SP2) or newer.
| Operating System | Browser |
|---|---|
| Windows XP, Vista, 7, 8 & 10 |
Chrome Edge Firefox 9+ Internet Explorer 8+ Opera |
| OS X 10.8 - 10.12 |
Chrome Firefox Safari |
| Ubuntu 14 - 16 |
Chrome Firefox |
| Android 2 - 7 |
Android Browser Chrome |
| iOS 6 - 11 |
Chrome Safari |
In addition to the above, both of the Old Bet Calculators are also compatible with Internet Explorer 6 and 7, but since Microsoft no longer supports Internet Explorer 6, 7, 8, 9 or 10 on any version of their Windows desktop operating system, a more modern browser should be used for security reasons.
Microsoft has also ended support for Windows XP & Vista, and Google has dropped support for their Chrome browser on both of these operating systems. Mozilla has reduced support for their Firefox browser on Windows XP & Vista, and is likely to end support altogether in September 2017. The options for using a browser that still receives security updates on these older operating systems are therefore very limited.
