Test for Success Criterion 1.1.1

About

Checked Elements: applet
Check to see that all applets have alt attribute, check there is text between <applet> and </applet>.

Short Description

Provide a text alternative for an applet by using the alt attribute to label an applet and providing the text alternative in the body of the applet element. In this technique, both mechanisms are required due to the varying support of the alt attribute and applet body text by user agents.

WCAG 2.0

Principle 1: Perceivable
Information and user interface components must be presentable to users in ways they can perceive.
WCAG 2.0: Principle 1
Guideline 1.1: Text Alternatives
Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language. Understanding Guideline 1.1
Success Criterion 1.1.1: Non-text Content (Level A)
Non-text Content: All non-text content that is presented to the user has a text alternative that serves the equivalent purpose, except for the situations listed below. (Level A).
  • Controls, Input: If non-text content is a control or accepts user input, then it has a name that describes its purpose. (Refer to Guideline 4.1 for additional requirements for controls and content that accepts user input.)
    • Time-Based Media: If non-text content is time-based media, then text alternatives at least provide descriptive identification of the non-text content. (Refer to Guideline 1.2 for additional requirements for media.)
  • Test: If non-text content is a test or exercise that would be invalid if presented in text, then text alternatives at least provide descriptive identification of the non-text content.
  • Sensory: If non-text content is primarily intended to create a specific sensory experience, then text alternatives at least provide descriptive identification of the non-text content.
  • CAPTCHA: If the purpose of non-text content is to confirm that content is being accessed by a person rather than a computer, then text alternatives that identify and describe the purpose of the non-text content are provided, and alternative forms of CAPTCHA using output modes for different types of sensory perception are provided to accommodate different disabilities.
  • Decoration, Formatting, Invisible: If non-text content is pure decoration, is used only for visual formatting, or is not presented to users, then it is implemented in a way that it can be ignored by assistive technology.
