The <input> Element

he most important form element is the <input> element.

The <input> element can be displayed in several ways, depending on the type attribute.

All the different input types are covered in the next Lesson.

The <select> Element

The <select> element defines a drop-down list:

Example

<select name="month">
  <option value="jan">jan</option>
  <option value="feb">feb</option>
  <option value="mar">mar</option>
  <option value="april">april</option>
</select>

The <option> elements defines an option that can be selected.

By default, the first item in the drop-down list is selected.

To define a pre-selected option, add the selected attribute to the option:

Example

The <textarea> Element

The <textarea> element defines a multi-line input field (a text area):

Example

The rows attribute specifies the visible number of lines in a text area.

The cols attribute specifies the visible width of a text area.

This is how the HTML code above will be displayed in a browser:

The <button> Element

The <button> element defines a clickable button:

Example

<button type="button" onclick="alert('submited!')">submit!</button>
