Working Calculator using HTML CSS and jQueryHello readers, Today in this blog you’ll learn how to build a Calculator using HTML CSS & jQuery. Previously I have shared a Working Analog Clock using HTML CSS & Javascript, now it’s time to create a Working Calculator using jQuery.
As you can see in the image, this is a Calculator. You will find a calculator program the same as this on a very familiar website like CodePen, but that program will be very difficult. If you are a beginner or watching for simple code then definitely difficult for you to understand.
In the image, there are some buttons and numbers. When you click on that specific button, the number of that button will be shown on the display. If you’re feeling difficult to understand what I am saying. You can watch a full video tutorial on this program (Working Calculator).

             document.forms.display.value += 1;
             document.forms.display.value += 2;
             document.forms.display.value += 3;

             document.forms.display.value += '.';
             if (display.value == "") {
               alert("Please enter any numbers to calculate!");
