Creating Accessible Web Content
This checklist provides basic guidelines to help you create web content that is accessible to persons with disabilities.
Images & animations
- Use the alt attribute to describe the function of each visual. Example:
- HTML Source Code: <img src="art/logo-green.gif" alt="Access Board Logo">
Provide captioning and transcripts of audio, and descriptions of video.
- Web pages shall be designed so that all information conveyed with color is also available without color. For example, a web page that directs a user to "press the green button to start" should also identify the green button in some other fashion than simply by color.
- Use sufficient contrast to make things easy to see.
Documents should be readable without requiring an associated style sheet.
Use the client-side map and text for hotspots.
- Avoid using tables for layout and design. If tables are used for layout purposes, do not us the <th> tag. For data tables, row and column headers shall be identified.
- For a detailed explanation with code examples, visit
Use the noframes element and meaningful titles.
Avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. For example, no flashing or moving text.
Applets and Plug-Ins
- Provide link to external program or plug-in, if required to open a file. (Example: Adobe Acrobat link for PDFs included in the County Footer.)
- LimeSurvey, the ISD-provided form tool, is compliant with accessibility standards for forms. To gain access to the LimeSurvey application, contact the ISD Help Desk.
- Follow these guidelines when creating forms in other applications.
- Use “Label” to describe each form element.
- Provide descriptive direction and cue to fill out the form.
