Fabric.js Textbox top Property

  • Last Updated : 22 Jan, 2021

In this article, we are going to see how to set a position relative to the top of a canvas Textbox using top Property FabricJS. The canvas means Textbox is movable and can be stretched according to requirements. Further, the Textbox can be customized when it comes to initial stroke color, fill color, stroke width, or size.

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 set the position relative to the top of the canvas Textbox using top property, and render the Textbox on the Canvas as given in the example below.

Syntax:

fabric.Textbox('text', {
    top: number
});

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

  • top: It specifies the position relative to the top.

Example: This example uses FabricJS to set a position relative to the top of the canvas textbox.

        // Create a new Textbox instance 
        var text = new fabric.Textbox(
            'A Computer Science Portal', {

            top: 250
        });
