        //==== Decrease font size by 1pt.
        lblOutput.Font.Size = currentSize - 1;
    }
    protected void btnIncreaseFont_Click(object sender, EventArgs e)
    {
        //==== Get the current font size of the lable and remove pt concated with font size.
        int currentSize = Convert.ToInt32(lblOutput.Font.Size.ToString().Replace("pt", ""));

        //==== Increase font size by 1pt.
        lblOutput.Font.Size = currentSize + 1;
