Size Mode for Syncfusion React Components

26 Mar 202518 minutes to read

An application that is designed to be accessed through a web browser on various devices, including desktop computers and mobile devices, may have a distinct layout or user interface on a mobile device compared to a desktop computer to better suit the smaller screen size.

Syncfusion React components support both touch (bigger) and normal size modes. Touch mode creates a responsive design for mobile devices by adding the e-bigger class, which enhances interactions, visibility, and the overall experience.

Size mode for application

The user can enable touch mode (bigger) for the entire application by adding the e-bigger class to the body element in the index.html file as follows:

  <body className="e-bigger">
    ...
  </body>

Size mode for a component

The user can enable touch mode (bigger) for a component by adding the e-bigger class to the div element that contains the component. Another way of enabling touch mode is by adding the e-bigger class using the available cssClass property of the component.

import * as React from 'react';
import * as ReactDom from 'react-dom';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import { enableRipple } from '@syncfusion/ej2-base';
//Enable ripple effect
enableRipple(true);
function App() {
    const content = "Button";
    return (<div className="e-bigger">
          <ButtonComponent content={content}></ButtonComponent>
        </div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));
import * as React from 'react';
import * as ReactDom from 'react-dom';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import { enableRipple } from '@syncfusion/ej2-base';
//Enable ripple effect
enableRipple(true);
function App() {
  const content = "Button";
    return (
        <div className="e-bigger">
          <ButtonComponent content={content}></ButtonComponent>
        </div>
    );
}
export default App;
ReactDom.render(<App />,document.getElementById('sample'));

Change size mode for application at runtime

The user can change the size mode of the application between touch and normal (mouse) mode at runtime by adding and removing the e-bigger class. The following steps explain how to change the size mode of an application at runtime:

import * as React from 'react';
import * as ReactDom from 'react-dom';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import { CalendarComponent } from '@syncfusion/ej2-react-calendars';
import { enableRipple } from '@syncfusion/ej2-base';
//Enable ripple effect
enableRipple(true);
function App() {
    const touchContent = "Touch Mode";
    const mouseContent = "Mouse Mode";
    function btnClick() {
        document.body.classList.add('e-bigger');
    }
    ;
    function mouseClick() {
        document.body.classList.remove('e-bigger');
    }
    return (<div>
          <ButtonComponent id='touch' content={touchContent} onClick={btnClick.bind(this)}></ButtonComponent>
          <ButtonComponent id='mouse' content={mouseContent} onClick={mouseClick.bind(this)}></ButtonComponent>
          <div>
            <CalendarComponent id="calendar"/>
          </div>
      </div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));
import * as React from 'react';
import * as ReactDom from 'react-dom';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import { CalendarComponent } from '@syncfusion/ej2-react-calendars';
import { enableRipple } from '@syncfusion/ej2-base';
//Enable ripple effect
enableRipple(true);
function App() {
    const touchContent = "Touch Mode";
    const mouseContent = "Mouse Mode";
    function btnClick() {
        document.body.classList.add('e-bigger');
    };
    function mouseClick() {
        document.body.classList.remove('e-bigger');
    }
    return (
        <div>
          <ButtonComponent id='touch' content={touchContent} onClick={btnClick.bind(this)}></ButtonComponent>
          <ButtonComponent id='mouse' content={mouseContent} onClick={mouseClick.bind(this)}></ButtonComponent>
          <div>
            <CalendarComponent id="calendar"/>
          </div>
      </div>
    );
}
export default App;
ReactDom.render(<App />,document.getElementById('sample'));

Change the font size for all components

The user can change the font size for all the components by overriding the CSS for the e-control class as follows:

    .e-control, .e-control [class^='e-'], .e-control [class*=' e-'] {
      font-size: 1rem;
    }

Change the font family of Syncfusion React components

The font family of Syncfusion React components can be changed by using the e-control class. This class is present in all Syncfusion components and allows the user to change the font family of all Syncfusion React components in an application.

.e-control {
  font-family: Arial !important;
}

By including the above CSS code block in the style sheet of the application, the user can change the font-family of all Syncfusion components.
