8.6 WCAG 2.1 Success Criterion 1.3.2 − Meaningful Sequence
If the content needs to be read in a certain order to make sense, ensure the webpage is written/coded in a way which indicates this order.
Before Rectification
In this example, the webpage has been built in such a way that the screen readers will read the two headings first and then the content.
After Rectification
If the webpage is correctly coded, the reading order will be more logical. In this case each piece of content follows its respective heading.
