Accessibility

We want everyone to be able to read Periodica comfortably. This page explains what the site offers, how to use the tools already on your phone or computer, and how to tell us when something gets in your way.

Reading comfort

Every page has a Reading comfort control, marked “Comfort”. On a computer it sits at the top of the page, above the Periodica name. On a phone it is inside the Menu. It opens a short list of settings. They change how the page looks, not what it says.

• Calm layout: plain background, no patterns or frames, no movement, plain labels.
• Stop animations: nothing moves unless you press it.
• Higher contrast: darker text, solid backgrounds, visible borders.
• Text size: Standard, Larger, Largest or Extra large.
• Dyslexia-friendly text: changes the font to Atkinson Hyperlegible and adds space between letters, words and lines. It also removes italics.
• Reading ruler: a soft band that follows your line as you read.
• Reset to the standard view: turns every setting off and clears your saved choices.

You can combine the settings. Your Reading comfort choices are saved only in this browser, so they are there on your next visit. To clear your choices, choose “Reset to the standard view”.

Settings on your device

If your phone or computer is set to reduce motion, the site follows that setting, even if you never open Reading comfort. The site also follows your device’s high-contrast and forced-colours settings.

You can move through the site with a keyboard: Tab moves to the next link or button, Shift and Tab moves back, and Enter or Space presses a button. If you find anything you cannot reach or use with a keyboard, please tell us.

The Quiet Corner

The tools in the Quiet Corner work with a keyboard as well as by touch or mouse. Nothing in the Quiet Corner plays sound until you turn it on.

Read it to me reads a short text aloud. It uses a voice built into your device. It is a feature of your device or browser, not of Periodica. You can pause, stop, choose a slower speed and pick from the voices on your device. If your browser has no voice the page can use, the button tells you so.

Having a page read aloud

Most phones and computers can read any web page aloud, including our articles. These are features of your device or browser, not of Periodica.

• iPhone and iPad: turn on Speak Screen in Settings, under Accessibility, then Spoken Content. Swipe down from the top of the screen with two fingers to start.
• Android: turn on Select to Speak in Settings, under Accessibility. Tap its icon, then tap the text you want to hear.
• Microsoft Edge: choose Read aloud from the menu, or press Ctrl, Shift and U.
• Google Chrome: open Reading mode from the menu and press Play.
• Safari on a Mac: Reader shows the article on its own; the Mac’s Spoken Content setting can read it aloud.

You can also make text bigger with your browser’s zoom (Ctrl or Command and the plus key). The page reflows to fit.

Language

Periodica is in English for now. French is planned. Your browser may offer to translate pages; machine translation can get health information wrong, so check anything important in the English text or with a health professional.

Where we are

We are working toward WCAG 2.2, Level AA. The site has not yet been independently tested.

WCAG (the Web Content Accessibility Guidelines) is a widely used set of guidelines for making websites easier to use for people with disabilities. Some parts of the site may not work well for everyone yet. We fix what we find, and what you tell us helps us find it.

Tell us about a barrier

If something on the site gets in your way, we want to know. Please tell us:

• the page (the web address, or its title)
• what you were trying to do
• what happened
• if you like, the device, browser or assistive technology you use

Write to us through the contact form or by email at hello@botanique.care.

A person reads every message. We will reply as soon as we can, tell you what we can change, and, where we can, offer the information another way in the meantime. We only use what you send us to reply and to fix the problem (see our Privacy Policy).
