Editorial Note

This article is an entry in our AppInnovation Contest. Articles in this sub-section are not required to be full articles so care should be taken when voting.


Engineering Calculator VOLTA-2012 is implemented as HTML 5 web application project that adheres to software paradigm of separation of programming concerns, namely:

  • Content: HTML5
  • Presentation: CSS3
  • Functionality: Javascript/jQuery

Entire project is encapsulated in a single text file with extremely small digital footprint (less than 10kB). It does not require any graphic files, like .jpg or .png, etc. All aesthetic enhancements, like: rounded corners, color gradients, borders and shadows are achieved exclusively via CSS3 styling, thus resulting in small application footprint and very fast web page load.


Engineering Calculator VOLTA-2012 extends the capability and application scope of its predecessor, previously published online [1,2] and partially described on Codeproject (see the link: Engineering Calculator VOLTA-2012)


Working Demo of Engineering Calculator VOLTA-2011 is available online: click on the snapshot image shown below and you will be redirected to the demo page implemented fully-functional calculator:
