Common Confusions - 2 Topics

Why does the text look uppercase but the HTML source still shows lowercase?

The text-transform property changes only the visual display of text, not the actual HTML content. So the source text remains unchanged.

💡 Text-transform is a visual style, not a content change.

Why doesn't text-transform work on input fields or textareas?

Some form elements need special handling or additional CSS to apply text-transform. By default, text-transform may not affect user input fields.

💡 Use text-transform carefully on form inputs; test in browser.

Concept Snapshot

text-transform changes how text looks without changing the HTML. Common values: uppercase (all caps), lowercase (all small), capitalize (first letter caps). Tailwind uses classes like 'uppercase' and 'lowercase' to apply these. Visual only: source text stays the same. Useful for styling headings or normalizing text appearance.
