Aesthetic enhancement of HTML5 web elements via pure CSS3; no image files required

Introduction

 

The solution described in this article serves both practical and didactic purposes. This popular Electrical Engineering Calculator VOLTA demonstrates HTML5/CSS3 styling technique, which does not require any graphic files like .jpg or .png, etc. All aesthetic enhancements, like:

  • rounded corners
  • color gradients (in particular, color-stop property)
  • borders
  • shadows

are achieved exclusively via CSS3 styling, resulting in very small digital footprint and fast web page load. Following Demo and sample code snippets demonstrate aforementioned HTML5/CSS3 styling technique applied to the core elements of online calculator, i.e. input, button and div elements. The solution implements client-side jQuery scripting, making it rather universal, capable of running in off-line standalone mode (without Internet connectivity).

Demo screenshots

Following are sample screenshots of online Engineering Calculator utilizing aforementioned HTML5/CSS3 graphic enhancements (sample images pertain to the original VOLTA-2011 and subsequent versions including VOLTA-2013, etc.)

Aesthetic HTML5 Button elements

Note: All aesthetic enhancements are achieved via pure HTML5/CSS3 styling; project does not use any graphic/image files.

Design Notes

The box shadow effect could be achieved by using the following CSS code block shown in Listing 2:

Listing 2. Box Shadow effect using CSS
CSS
/* add shadows */
-moz-box-shadow: 5px 5px 10px rgba(0,0,0,0.3);
-webkit-box-shadow: 5px 5px 10px rgba(0,0,0,0.3);
box-shadow: 5px 5px 10px rgba(0,0,0,0.3);

Adding Tooltips. Further enhancement could be achieved by adding the context-sensitive help (a.k.a. Tooltips) to the buttons by using HTML elements "abbr" or "acronym". In this case no any Javascript is needed; the pop-up text will correspond to the title attribute of the abbr tag. Listing 3 demonstrates the sample implementation of this feature, pertinent to the Calculator Volta 2011

    </li>
    <li id="active">

Points of Interest

Browser compatibility 

Online Calculator Volta is compatible with all major Web Browsers that support HTML5, CSS3 and jQuery version(s) 2.0x

  • Mozilla FireFox v.23+
  • Google Chrome v.28+
  • Safari v.6+
  • IE9+
  • Opera v.15+

Desktop version

The first desktop version of the Engineering Calculator software was created as a contest submission via direct conversion tool (HTML5 into Windows application) provided by Intel Corporation during the Ultrabooks Application Innovation Contest (AIC 2012). It was placed at the Intel's online App store for some time.

Much better results were achieved by completely re-programming the app using Microsoft .NET framework (WPF/XAML/C#) in Visual Studio 2010.
