Accessibility and WCAG

Learn the basics of making a site easier for everyone to use.

Big Picture

One small picture can make this idea easier to hold.

Accessible page

  • Clear labels on forms.
  • Good color contrast.
  • Keyboard works for all actions.
  • Images have helpful alt text.

Hard page

  • Blank buttons with no labels.
  • Light gray text on white.
  • Mouse-only controls.
  • Images with no meaning.

VerdictAccessible pages are easier for more people and easier to test.

How It Moves

Short steps make the flow easier to see.

1

Check labels

Make sure buttons and inputs have names.

2

Check color

See if text stands out from the background.

Check keyboard

Move through the page without a mouse.

4

Check images

See if important images have alt text.

Step By Step

This is the same idea, stretched across time.

  1. 1

    Scan the page

    Look for the main inputs, buttons, and images.

  2. 2

    Try keyboard use

    Tab through the page and watch focus.

  3. 3

    Check text and color

    Make sure content is easy to read.

  4. 4

    Note the gaps

    List the parts that block use or slow people down.

One Small Model

Think of this like a tiny card you can keep in your pocket.

Accessible button

5 fields
Text:"Save"
Role:"button"
Focus:"Visible"
Contrast:"Good"
Label:"Clear"
A button should be easy to find, read, and use with a keyboard.
