The placeholder attribute and the <label> serve different purposes in providing hints and information for form fields.

placeholder Attribute:

• Input Format Guidance: Use placeholder to provide a brief example or format hint inside text, email, or password fields. Helpful for indicating the expected input without cluttering the form.
• Non-essential Information: Ideal for supplementary, non-critical information that doesn’t need a permanent label. Commonly used in search bars or short input fields.
• Conserving Space: Suitable for situations where saving space is crucial, as placeholders are visible within the input field.

Syntax:

<input type="text" placeholder="Enter your username">

Label Element:

• Accessibility: Essential for screen readers, providing context and also ensures understanding, especially for visually impaired users.
• Persistent Information: Use <label> for permanent, visible descriptions. Vital for maintaining information visibility.

Syntax:

<label for="username">Username:</label>
<input type="text" id="username" name="username">
