Accessibility is not a finishing touch; it is part of how a document is written and a page is built. Macalix Guides LLC is committed to making this site and the e-book usable by as many readers as possible, including people who use assistive technology.

Our standard
We aim to meet the Web Content Accessibility Guidelines version 2.1 at Level AA, the widely used standard that also supports the expectations of the Americans with Disabilities Act for a site like this one. We review the site against that standard as we publish, and we act on what we find.
What is built in
- Text in a system font that respects the reader's own text-size and contrast settings.
- Colour combinations chosen for legibility, with body text well above the minimum contrast ratio.
- A page structure of headings in order, so screen readers can move between sections.
- A visible keyboard focus outline on every link and control, and a skip link to reach the content.
- Meaningful alternative text on every image, describing what matters about it.
- Forms with a label on every field, and clear notes on what each one asks for.
- A layout that reflows without loss when text is enlarged, and that works at any screen width.
- Pages that need no external requests, so they load quickly and stay readable on a slow connection.
The e-book
Accessibility has shaped the two layouts of the e-book. The PDF is set with a clear reading order and real text rather than a picture of text, so it can be enlarged and searched. The EPUB is written to reflow, so it responds to a reader's own font, size and contrast choices on any device. Where a table appears, its meaning is carried in the text around it as well as in the table itself, so no information depends on layout alone.
Design choices we made on purpose
Some decisions that look like style are really accessibility. The pages use one column of prose rather than a busy grid, so a reader can follow a line without losing it. Body text is large and generously spaced, which helps readers with low vision and readers who read quickly. Colour is never the only signal: a warning is marked by a heading and a border as well as by its tint. Buttons and links are written as actions, so their purpose is clear out of context.
Where we may still fall short
We are honest that no site is perfect, and that assistive technology differs from reader to reader. Two areas deserve a note. First, the small toolbar icons are decorative and paired with a text label, so they add nothing a screen reader must interpret; if any icon ever loses its label, that is a fault and we would want to know. Second, the e-book's PDF layout may be harder for some readers than the EPUB; where that is the case, we recommend the EPUB, which reflows by design.
How to tell us
If you meet a barrier on this site or in the e-book, please write to [email protected]. Describe the page and what happened, and, if you are willing, the technology you were using. We will look into it and reply. Where a fix is needed, we would rather make it than be told about it twice.
Continuous work
We treat accessibility as ongoing rather than finished. Each new chapter is checked against the standard as it is published, and we revisit older pages when we make changes. If you would like to be told when a specific fix is made, say so in your message and we will write back when it is done.
