>When the default is true

$3

If text increase / decrease isn't working for your size your probably not using responsive font size units (such as em, rem etc.).
In that case you can initialize the accessibility tool like this:
`javascript
new Accessibility({textPixelMode: true})
`
You can change the factor of the font size difference between every iteration (default is 12.5):
`javascript
new Accessibility({textSizeFactor: 4})
`

$3

Cancel all buttons animations:
`javascript
new Accessibility({animations: {buttons: false}})
`

$3

You can position the accessibility icon in any place on the screen. The default position is bottom right:
`css
body {
--_access-icon-top: 50px;
--_access-icon-left: 50px;
--_access-icon-right: unset;
--_access-icon-bottom: unset;
}
`

$3

You can change the default icon as described here

From version 3.0.1 the session will be persistent even after the user will refresh the page.
To disable this feature use:
`javascript
const options = {
session: {
persistent: false
}
};
new Accessibility(options);
`

$3

You can toggle the menu buttons directly via the exposed API:
`javascript
var instance = new Accessibility();

instance.menuInterface.increaseText();

instance.menuInterface.decreaseText();

instance.menuInterface.increaseTextSpacing();

instance.menuInterface.decreaseTextSpacing();

instance.menuInterface.invertColors();

instance.menuInterface.grayHues();

instance.menuInterface.underlineLinks();

instance.menuInterface.bigCursor();

instance.menuInterface.readingGuide();

instance.menuInterface.textToSpeech();

instance.menuInterface.speechToText();

instance.menuInterface.disableAnimations();
`

You can also override the functionality like this:
`javascript
instance.menuInterface.increaseText = function() {
// My own way to increase text size . . .
}
`

$3

You can add buttons that will open a model with custom iframes (for accessibility terms for example) like so:
`javascript
const options = {
iframeModals: {
iframeUrl: 'https://github.com/ranbuch/accessibility',
buttonText: 'terms',
icon: 'favorite',
emoji: '❤️'
}
};
new Accessibility(options);
`

In case you will not provide the "icon" and the "emoji" we will use this setup:

icon: 'policy',
emoji: '⚖️'

You can find icons [here

$3

You can add buttons that will invoke custom functions like so:
`javascript
const options = {
customFunctions: {
method: (cf, state) => {
console.log('The provided customFunctions object:', cf);
console.log('Toggle state:', state);
},
buttonText: 'my foo',
id: 1,
toggle: true,
icon: 'psychology_alt',
emoji: '❓'
}
};
new Accessibility(options);
`

In case you will not provide the "icon" and the "emoji" we will use this setup:

icon: 'psychology_alt',
emoji: '❓'

You can find icons [here

You have to provide the "id" parameter. This would also be your way to identify the button in case you are using more then on function while using the same custom function.

You have to provide the "toggle" parameter. This will determine whether the button will toggle his state active state (on and off) or not.

$3

You can use CSS variables to change the styling of the menu. Here is an example of how you can change the exposed variables in order to change the theme to dark mode:
`css
:root {
--_access-menu-background-color: #000;
--_access-menu-item-button-background: #222;
--_access-menu-item-color: rgba(255,255,255,.6);
--_access-menu-header-color: rgba(255,255,255,.87);
--_access-menu-item-button-active-color: #000;
--_access-menu-item-button-active-background-color: #fff;
--_access-menu-div-active-background-color: #fff;
--_access-menu-item-button-hover-color: rgba(255,255,255,.8);
--_access-menu-item-button-hover-background-color: #121212;
--_access-menu-item-icon-color: rgba(255,255,255,.6);
--_access-menu-item-hover-icon-color: rgba(255,255,255,.8);
--_access-menu-item-active-icon-color: #000;
}
`

Alternatively, you can suppress the default CSS injection altogether (not recommended):
`javascript
new Accessibility({suppressCssInjection: true});
`
You can also replace the icons by replacing the content attribute with the CSS variables currently being used.

You can suppress the default HTML injection altogether:
`javascript
const instance = new Accessibility({suppressDomInjection: true});
`
You will need to provide your own DOM and call menuInterface functions.

You might need to replace the font-face-src:
`javascript
const options = {
icon: {
fontFaceSrc: ['https://fonts.bunny.net/icon?family=Material+Icons']
}
};
new Accessibility(options);
`

Another example with font-awesome icons:
`javascript
const options = {
icon: {
fontFaceSrc: ['https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.5.1/css/v4-font-face.min.css'],
fontFamily: '"FontAwesome"',
img: '[optional - URL for an image that will replace the menu icon]',
closeIcon: '[optional - replacement text for the close menu icon]',
resetIcon: '[optional - replacement text for the reset all icon]',
closeIconElem: {
type: 'i',
attrs: {
'class': 'fa fa-window-close',
'aria-hidden': 'true'
}
},
imgElem: {
type: 'i',
attrs: {
'class': 'fa fa-universal-access',
'aria-hidden': 'true'
}
},
resetIconElem: {
type: 'i',
attrs: {
'class': 'fa fa-refresh',
'aria-hidden': 'true'
}
}
}
};
new Accessibility(options);
`
`css
:root {
--_access-menu-item-icon-increase-text: "\f062";
--_access-menu-item-icon-decrease-text: "\f063";
}
`
Obviously you will need to add the missing variables for the rest of the fonts.

You can determine the order of the modules:
`javascript
new Accessibility({
modulesOrder: [
{
type: AccessibilityModulesType.textToSpeech,
order: 0
}
]
});
``
