Below are some general accessibility tips to assist getting started with digital accessibility. The tips are based on global industry web standards created by the [W3C Web Accessibility Initiative](https://www.w3.org/WAI/).

## Use color wisely

- Do not use color alone to convey information
- Check that contrast between text or UI elements and background meet WCAG 2.1 AA contrast standards

## Create structure with headings and proper markup

- Pages that are well structured, follow proper syntax, and pass the W3C validator are most accessible
- Heading tags (<H1> – <H6>) can make the site more navigable to users of assistive technology like screen readers
- Use skip links to allow users to go directly to desired content or to skip over navigation elements that are common to each page. Skip links benefit screen reader users and other users who do not use a mouse

## Use ALT text on all images

- Alt text should be included for all images on a web page
- Structural or decorative images (spacers, backgrounds) can contain empty or “null” text, i.e. alt=””

## Provide captions for video and transcripts for audio

- Auto captions are not sufficient.  Captions must be accurate and synchronized with the video.
- Make sure any podcasts or audio-only files include a transcript of the audio

## Use Descriptive language

- Use descriptive titles, headers, and link text to provide added Context. Avoid using the terms ‘Click Here’, ‘See More’, or ‘Learn More’
- Do not rely solely on references to shape, size, or position to describe content

## Avoid using tables for layout

- Use stylesheets and div tags for visual layout
- Use basic header information for data tables (the <th></th> element)
- Use linearized data tables for complex data

## Create accessible forms

- Ensure forms are logical and easy to use, are keyboard accessible, and also associate form labels with controls
- Reference [WebAim’s Creating Accessible Forms](https://webaim.org/techniques/forms/) to ensure forms are accessible
