+# 1.3.2 Meaningful Sequence
+
+- Level: A
+- Guideline: 1.3 Adaptable
+- Principle: 1 Perceivable
+
+## What it is
+
+When the sequence in which content is presented affects its meaning, a correct reading sequence can be programmatically determined.
+
+## How to test
+
+- Check: When the sequence in which content is presented affects its meaning, a correct reading sequence can be programmatically determined.
+- Use the sufficient techniques below as acceptable methods when applicable.
+- Confirm none of the common failures apply.
+
+## Sufficient techniques (W3C)
+
+- G57: Ordering the content in a meaningful sequence
+- H34: Using a Unicode right-to-left mark (RLM) or left-to-right mark (LRM) to mix text direction inline
+- H56: Using the dir attribute on an inline element to resolve problems with nested directional runs
+- C6: Positioning content based on structural markup
+- C8: Using CSS letter-spacing to control spacing within a word
+- C27: Making the DOM order match the visual order
+- PDF3: Ensuring correct tab and reading order in PDF documents
+
+## Common failures (W3C)
+
+- F34: Failure of Success Criterion 1.3.1 and 1.3.2 due to using white space characters to format tables in plain text content
+- F33: Failure of Success Criterion 1.3.1 and 1.3.2 due to using white space characters to create multiple columns in plain text content
+- F32: Failure of Success Criterion 1.3.2 due to using white space characters to control spacing within a word
+- F49: Failure of Success Criterion 1.3.2 due to using an HTML layout table that does not make sense when linearized
+- F1: Failure of Success Criterion 1.3.2 due to changing the meaning of content by positioning information with CSS
