Our approach
We aim to make ToolMix Lab usable on small and large screens, with clear labels, readable text and keyboard-operable controls. Calculators use structured headings, labelled inputs, visible focus and messages that explain incomplete or invalid data.
Using the tools
Use the Skip to content link to move past the main navigation. Tools are grouped in the catalogue and site map. The calculation method and examples are available as ordinary page text. JavaScript is required to run interactive calculations; the page explains this when it is disabled.
Some tools include SVG diagrams and detailed result tables. The accompanying values and explanations provide context, while the diagrams help illustrate the model. Browser zoom and device settings can change layout; report any control or result that becomes difficult to use.
Limitations and feedback
Accessibility checks are part of development, but automated checks alone do not establish full conformance or cover every assistive-technology combination. We do not claim independent accessibility certification.
If you encounter a barrier, email toolmixlab@gmail.com. Include the page address, browser, device and assistive technology if relevant, and describe what you were trying to do. We use this feedback to improve controls, explanations and layouts.
