The HTML <textarea> element's rows attribute, which specifies the visible height of the text area in lines, is widely supported across all major modern web browsers. This includes: Google Chrome, Mozilla Firefox, Microsoft Edge, Apple Safari, and Opera.

 

This attribute has been a fundamental part of HTML for a long time, and its implementation is consistent across these browsers, ensuring reliable rendering of the specified number of rows for the text area. While CSS properties like height can also control the visual height, the rows attribute provides a convenient and well-supported method for defining the initial height in terms of lines of text.
