# 1 What formats do I need to produce and why?

ClavertonDown can produce:

- HTML book
- HTML page
- Standard, clear and large print PDF
- Word document
- EPub book

From a technical point of view only three of these formats of mathematical text are accessible:

- HTML using MathJax to render all mathematical text (HTML book and page)
- HTML formats must meet WCAG 2.1 Level AA requirements and use MathJax to render all mathematical text.
- You can check your document meets the legal requirement of WCAG 2.1 Level AA with e.g. Accessibility Insights for Web plugin for Chrome
- You can check it is MathJax by right clicking on the expression (try it in the HTML version): \[x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}\]

- Word document using in-built Equation Editor for all mathematical text
- Word formats must pass the in-built Accessibility Checker and use the in-built Equation Editor for all mathematical text.
- You can use the in-built Word Accessibility Checker and information on Making your Word documents accessible to check your document.
- You can use Review -> Read Aloud (Alt + Ctrl + Space) to check the maths

- EPub3 using MathML for all mathematical text:
- If the HTML format is accessible then the EPub3 output from ClavertonDown will be also

The output from ClavertonDown will meet these requirements as far as possible. However, we cannot stop you from doing things which will fail to meet requirements. In particular, if you use images, sound, videos, colour or interactive/dynamic elements within the HTML you will need to ensure that you have done so within the accessibility requirements.
