VI. Styling Placeholder Text

    font-style: italic;
}

<style>
input::placeholder {

}
input {
    padding: 10px;
    border: 1px solid #ccc;
    border-radius: 4px;
}
</style>

<input type="text" placeholder="Type something...">

VII. Accessibility Considerations

Creating accessible web forms is crucial for users with disabilities. Placeholder text should not replace labels since screen readers may not adequately convey information conveyed through placeholders.

Always use a label for inputs along with the placeholder attribute.
Avoid using placeholders as the sole form of input guidance.
Ensure sufficient color contrast between the placeholder text and the input field background.
Limit the use of placeholder text for critical information, as it disappears when the user starts typing.
