you can adjust the size of the TextArea by applying specific classes:

Property	Description

index.jsx

import * as React from 'react';
import * as ReactDom from 'react-dom';

// To render TextArea.
function App() {
    return (
        <div className='wrap'>
            <h4> Small Size </h4>

            <div className="e-input-group e-small">
                <textarea className="e-input" placeholder="Enter your comments" onFocus={floatFocus} onBlur={floatBlur}></textarea>
            </div>

            <h4> Bigger Size </h4>

            <div className="e-input-group e-bigger">
                <textarea className="e-input" placeholder="Enter your comments" onFocus={floatFocus} onBlur={floatBlur}></textarea>
            </div>
        </div>
    );
}

function floatFocus(args) {
    args.target.parentElement.classList.add("e-input-focus");
}

function floatBlur(args) {
    args.target.parentElement.classList.remove('e-input-focus');
}

export default App;
ReactDom.render(<App />, document.getElementById('input-container'));

index.tsx

// To render TextArea.
function App() {

            <h4> Small Size </h4>

            <div className="e-input-group e-small">
                <textarea className="e-input" placeholder="Enter your comments" onFocus={floatFocus} onBlur={floatBlur}></textarea>

Filled and outline mode

The Filled and Outline modes can be enabled in the TextArea component by adding the e-outline or e-filled class to the cssClass API.
By adding these classes, users can choose between a filled or outline appearance for the TextArea component, aligning with the design aesthetics of their application.

index.jsx

// Import the TextArea.
import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import * as ReactDom from 'react-dom';

// To render TextArea.
function App() {
    return (
        <div className='wrap'>
            <label className="custom-input-label"> Filled TextArea </label>
            <div id='container'>
                <TextAreaComponent id='filled' placeholder="Filled" floatLabelType="Auto" cssClass="e-filled"></TextAreaComponent>
            </div>

                <TextAreaComponent id='outlined' placeholder="Outlined" floatLabelType="Auto" cssClass="e-outline"></TextAreaComponent>
            </div>
        </div>
    );
}

ReactDom.render(<App />, document.getElementById('input-container'));

index.tsx

            <div id='container'>
                <TextAreaComponent id='filled' placeholder="Filled" floatLabelType="Auto" cssClass="e-filled"></TextAreaComponent>
            </div>
            <label className="custom-input-label"> Outlined TextArea </label>
            <div id='container1'>
                <TextAreaComponent id='outlined' placeholder="Outlined" floatLabelType="Auto" cssClass="e-outline"></TextAreaComponent>
            </div>
