Test for Success Criterion 1.3.1

Checked Elements: all

Checks that if a table has both a <summary> attribute and a <caption> element, that the <summary> is not identical to the <caption>.

The objective of this test is to programmatically associate captions for data tables where captions are provided in the presentation. The caption for a table is a table identifier and acts like a title or heading for the table. <br> The caption element is the appropriate markup for such text and it ensures that the table identifier remains associated with the table, including visually (by default). In addition, using the caption element allows screen reading software to navigate directly to the caption for a table if one is present. <br> The caption element may be used whether or not the table includes a summary attribute. The caption element identifies the table whereas the summary attribute gives an overview of the purpose or explains how to navigate the table. If both are used, the summary should not duplicate information in the caption .

Principle 1: Perceivable

Information and user interface components must be presentable to users in ways they can perceive.

Guideline 1.3: Adaptable

Create content that can be presented in different ways (for example simpler layout) without losing information or structure. Understanding Guideline 1.3

Success Criterion 1.3.1: Info and Relationships (Level A)

Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text. Understanding: Success Criterion 1.3.1
