Should I use placeholder text?

Placeholder text can be used as an attribute for almost every HTML input type, and misguided designers and developers don't hesitate. It is tempting to provide text help for complex forms or omit input labels to improve aesthetics. However, employing placeholder text to do so causes many usability issues.

Why are placeholders important?

Placeholders are frequently used to provide important input formatting instructions or are used in place of a more appropriate label element (more on that in a bit).

When to use placeholder HTML?

If you want to set a hint for text area or input field, then use the HTML placeholder attribute. The hint is the expected value, which gets displayed before the user enters a value, for example, name, details, etc.

Is value and placeholder same?

The placeholder text, although it appears in the same place as the value, is not a value. It is never submitted, and only shows up if there is no value.
