9. Some Other Input Type attributes in Form

6. 1. Text Input Controls
Input text controls are used to collect User data as a free text. On the web page, it will form a
rectangle box where Users can input the data. There are different types of input text controls that
can be used in the HTML forms. There are three types of text input used on forms −
1. Single-line text input controls − This control is used for items that require only one line of
user input, such as search boxes or names. They are created using HTML <input> tag. This allows the
user to enter only a single line of data. A typical example of such input text controls is for entering
the name, search box, city, etc.
2. Password input controls − This is also a single-line text input but it masks the character as soon
as a user enters it. They are also created using HTMl <input> tag. As the name suggests this is typically
used for the password field. This works in the same way as the input text field but the text gets
masked for safety purposes.
3. Multi-line text input controls − This is used when the user is required to give details that may
be longer than a single sentence. Multi-line input controls are created using HTML <textarea> tag.
This input control type allows the user to enter data of multiple lines. Typical usage of such input
controls is for comments, addresses, description and so on.
