In this section, we will explore the fundamental form elements in HTML: <input>, <textarea>, and <select>. These elements are essential for creating interactive forms that allow users to input data.
- Input Element
The <input> element is one of the most versatile form elements in HTML. It can be used to create various types of input fields, such as text, password, email, number, and more.
Common Input Types
- Text Input: Allows users to enter a single line of text.
- Password Input: Masks the input text for security.
- Email Input: Validates the input to ensure it is a valid email address.
- Number Input: Allows users to enter numerical values.
- Checkbox: Allows users to select one or more options.
- Radio Button: Allows users to select one option from a group.
Example
<form> <label for="name">Name:</label> <input type="text" id="name" name="name"><br><br> <label for="password">Password:</label> <input type="password" id="password" name="password"><br><br> <label for="email">Email:</label> <input type="email" id="email" name="email"><br><br> <label for="age">Age:</label> <input type="number" id="age" name="age"><br><br> <label for="subscribe">Subscribe to newsletter:</label> <input type="checkbox" id="subscribe" name="subscribe"><br><br> <label for="gender">Gender:</label> <input type="radio" id="male" name="gender" value="male"> Male <input type="radio" id="female" name="gender" value="female"> Female<br><br> <input type="submit" value="Submit"> </form>
