When building websites, understanding the various attributes available in HTML is crucial. One such attribute is the rows attribute, which plays an important role in defining the layout and structure of certain HTML elements, especially in text areas. This article will provide a comprehensive guide on the rows attribute, its usage, syntax, and impact on web design, making it easy for beginners to grasp its significance.
What is the rows Attribute?
The rows attribute is a global attribute in HTML primarily used in the <textarea> element. It defines the number of visible rows of text in the text area. With this attribute, developers can customize text input areas, enhancing user experience by providing a clear interface for data entry.
How to Use the rows Attribute
Syntax of the rows Attribute
The rows attribute can be added directly within the <textarea> tag. Here is the basic syntax:
<textarea rows="number_of_rows"></textarea>
Example of Implementation
Below is an example that illustrates how to implement the rows attribute:
<textarea rows="4">This is a text area with 4 rows.</textarea>
In the example above, the text area will display four visible rows. You can type a longer text, and a scrollbar will appear once the text exceeds the visible area.
Value of the rows Attribute
Explanation of How to Specify Values
The value of the rows attribute must be a positive integer, indicating the number of text rows you want to display. For instance:

| 2 | Displays 2 visible text rows in the text area. |
| 5 | Displays 5 visible text rows in the text area. |
| 10 | Displays 10 visible text rows in the text area. |
Impact of Different Values on Element Behavior
Choosing a higher value for the rows attribute makes it easier for users to see and edit longer pieces of text, whereas a lower value could lead to a cramped interface, making it hard to read. Here’s how different row values affect the appearance:
<textarea rows="2">This text area has 2 rows.</textarea>
<textarea rows="5">This text area has 5 rows.</textarea>
<textarea rows="10">This text area has 10 rows.</textarea>
