**How to set default value in input field in HTML?**

Setting a default value in an input field can be useful in various scenarios. Whether you want to provide a pre-filled value or indicate the expected format, HTML offers simple ways to accomplish this. In this article, we’ll explore different methods to set default values in input fields and address some related frequently asked questions.

To set a default value in an input field in HTML, you can use the `value` attribute. This attribute allows you to specify the initial value that should be displayed when the page loads. Let’s look at an example where we set a default value in a text input field:

“`html

“`

In the above code snippet, the input field will be pre-filled with “Default Value” when the page loads. This default value can be changed by the user as they interact with the input field.

FAQs about setting default values in input fields:

12. How can I set a default value in a date or time input field?

Setting default values in input fields not only enhances the user experience by providing a starting point but also assists in conveying the desired input format. By utilizing the `value` attribute appropriately, you can make your HTML forms more effective and user-friendly.
