Once you have improved the MyPhoto style rules so they're as compact, efficient, and maintainable as possible, it is time to look into minification. Minification is the process of removing redundant characters from a file, without altering the actual information contained within it. In other words, minifying our myphoto.css file will reduce its overall size, while leaving the actual CSS style rules intact. This is achieved by stripping out any whitespace characters within our file. Stripping out whitespace characters has the obvious result that our CSS is now practically unreadable and impossible to maintain. As such, minified style sheets should only be used when serving a page (that is, during production), and not during development.
Clearly minifying your style sheet manually would be an incredibly time-consuming (and hence pointless) task. Therefore, there exist many tools that will do the job for us. One such tool is npm minifier. Visit
