Input Types and Attributes
Concept
Input Types and Attributes
Changing type gives you checkboxes, radio buttons, dates, and more — each with built-in browser behavior. placeholder, required, and disabled fine-tune how an input behaves.
Radio buttons only behave as a mutually exclusive group when they share the same name attribute — different names create independent, unrelated buttons.
- Explain the core idea behind Input Types and Attributes.
- Predict output before running a change.
- Test one realistic and one unusual input.
- Use the result to make the next decision.
- 1. Read one concept.
- 2. Change the example.
- 3. Run, compare, and explain.
- 4. Complete the challenge below.
Self-check before continuing
Without looking at the example, describe what changes when you modify one input in Input Types and Attributes. Then reopen the editor and prove your explanation with a small test.
You are ready to continue when you can predict, test, and explain the result.
Your turn
Add a required checkbox and two radio buttons (in the same name group) to a form.
Ask about this lesson or your next move. The guide explains the path without taking the work away from you.
