“Darkness” is a web browser extension that allows the user to change the appearance of certain light-colored websites into a dark color scheme. I personally designed a dark “Monokai” Darkness theme for Gmail, Google’s email service.
The client for Darkness specifically requested that I develop this Monokai Gmail theme using the CSS pre-processor SASS (Syntactically Awesome Style Sheets) rather than plain CSS. A couple of the many benefits of using SASS over plain CSS is that it can use custom variables and it can copy properties of elements of one SASS file into elements of another while still exporting everything into a single CSS file.
The colors of the Monokai Gmail theme were based on a pre-made list of color variables. My responsibility was to apply those color variables into Gmail’s web design. I also added some extra variables which were needed but didn’t exist before.
Developing this theme for Darkness was a little more challenging than it usually is for developing websites because we didn’t have access to Google’s original development CSS, and the live CSS of Gmail uses meaningless, obfuscated class names for all elements. I had to painstakingly reverse-engineer the CSS by using Chrome Developer Tools to inspect every nook and cranny of the website that needed its color changed.
Darkness, developed by Lifehack Labs, is an extension for the web browser Google Chrome. In addition to Gmail, Darkness can switch to dark color schemes for certain other websites including Google, Facebook, YouTube, and more. It’s available at the Chrome Web Store, where more than 100,000 people have installed this extension.
