In this tutorial, we are going to learn how to lock the horizontal skewing of a Textbox using FabricJS. Just as we can specify the position, colour, opacity and dimension of a textbox object in the canvas, we can also specify whether we want to stop skewing an object horizontally. This can be done by using the lockSkewingX property. Syntax new fabric.Textbox(text: String, { lockSkewingX : Boolean }: Object) Parameters text − This parameter accepts a String which is the text string that we want to display inside our textbox. options (optional) − This parameter is an Object ...

In this tutorial, we are going to learn to change strings to be displayed as a superscript using JavaScript. As the name suggests, the superscript string is displayed at the half-height of the normal string. Also, characters of the superscript string are smaller than the normal string characters.There are a lot of uses of the superscript string while writing the mathematical formulas. For example, A2, B2, 105, etc. Also, we can use the superscript to show the chemical formulas such as O22-, H-, etc.Here, using HTML or JavaScript, users can learn to display string as a superscript.Display string as subscript ...
