Last Updated : 22 Jan, 2021

In this article, we are going to see how to change the background color of the canvas Textbox using textBackgroundColor Property of FabricJS. The canvas means Textbox written is movable, rotatable, resizable, and can be stretched. But in this article, we will change the background color.

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

Syntax:

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

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

textBackgroundColor: It specifies the background color to be set.

Example: This example uses FabricJS Textbox textBackgroundColor Property to set the background color of the canvas textbox as given below:
