Key	Capability
Screen Reader	Screen reader is a tool where it would reads out texts on screen where user clicks on. For any html elements, if an aria label is available, the content from aria label would be read out loud, otherwise, it reads the text content of the element. There are 3 different speeds, normal, fast and slow.
Contrast	Contrast is a tool that removes background and replaces it with black or white to increase the difference in colours between text and the background to increase legibility. There are 3 modes, the invert colours, high contrast, and dark high contrast.
Saturation	Saturation is a tool that adjusts how colourful the colours are on screen, it has 3 different modes to lower saturation, increase saturation, or remove all the colours on screen (black and white).
Bigger Text	Bigger Text is a tool that increases the size of the texts on screen.
Text Spacing	Text Spacing is a tool that increases the spacing between each character on the screen to increase legibility and readibility.
Screen Mask	Screen Mask is a tool which dims the background and has a smaller focused area which follows the cursor sliding up and down the page.
Line Spacing	Line Spacing is a tool which increases the space between lines for greater readability.

Usage

Astral is built with Angular Elements. You can use it in your website in under 30 seconds. To add it, simply include the Javascript and initialize it:

Note: By default this function all will add all available features, for enabling only certain features, see the section below on Customizing Widget.

<script src="https://astral-accessibility.pages.dev/main.js"></script>
<script>
  initializeAstral();
</script>

Customizing Widget

Astral-Accessibility allows you to customize the widget to your needs. This mean you can enable the features you want and hide the features you may not need. You can choose which widgets should appear by passing an object inside of the inititalizeAstral function call. Inside the object include a key called enabledFeatures with the value of a list containing strings of which features you want enabled.

Here's an example:

<script>
  initializeAstral({
    filterWidget: ["Contrast", "Bigger Text", "Screen Mask"],
  });
</script>

Optionally we can choose which widgets should appear by passing an object inside of function call:

<script>
  initializeAstral({
    enabledFeatures: [
      "Screen Reader",
      "Contrast",
      "Saturation",
      "Bigger Text",
      "Text Spacing",
      "Screen Mask",
      "Line Height",
    ],
  });
</script>
