When a style does not appear, debug systematically:

1. Confirm the utility name and syntax are valid for the installed version.
2. Inspect the element's class attribute in the browser.
3. Check whether the class candidate appears in a scanned source file.
4. Inspect the generated CSS and computed styles.
5. Look for specificity, cascade layers, inline styles, or conflicting rules.
6. Check whether a parent clips or constrains the element.

A class being present in HTML does not guarantee a matching rule exists. Likewise, a generated rule may be overridden by another declaration. Distinguish generation problems from cascade problems before applying a workaround.
