Fabric.js Textbox backgroundColor Property

  • Last Updated : 20 Jan, 2021

In this article, we are going to see how to change the background color of the Textbox using Fabric.js. The Textbox in Fabric.js is movable and can be stretched according to requirement. Further, the Textbox can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

Approach: To make it possible, we are going to use a JavaScript library called Fabric.js. After importing the library, we will create a canvas block in the body tag which will contain the Textbox. After this, we will initialize instances of Canvas and Textbox provided by Fabric.js, change the background color of canvas Textbox using backgroundColor property and render on the Canvas as given in the example below.

Syntax:

fabric.Textbox('text', {
    backgroundColor: string
});

Parameters: This function accepts a single parameter as mentioned above and described below:

  • backgroundColor: It is the background color to be used on the Textbox.

Example: This example uses Fabric.js to change the background color of the Textbox canvas.

        var canvas = new fabric.Canvas("canvas");
  
        // Create a new Textbox instance 
        var text = new fabric.Textbox(
            'A Computer Science Portal', {
            width: 450,
            backgroundColor: 'green'
        });
  
        // Render the Textbox in canvas
