When Google included the CSS and JS Coverage tool, it helped to identify the culprits (it's one file.I think you know what needs to be done) and determining what CSS is used and unused.

In the past, I've mentioned how to get started with CSS (a beginner's guide) and 5 Methodologies for Architecting CSS, but today, I want to show a simpler way to create a better CSS structure for web sites. If they added a CSS and JS Coverage tool, it must be an important issue across the web. They look at it as a definite hindrance when loading web pages with CSS and JS bloat. This is why Google added the CSS and JS Coverage to their DevTools (Press F12 to see them) to eliminate unused CSS and JavaScript. You need a balance with CSS this makes it more art than science when laying the foundation for your web pages.
Does your site load quickly? Well, not if you load a large CSS file designated for your entire site and not for the current page. Once they visually saw the change, they would move on and not give the CSS a second thought. In my experience, I've watched a developer open a large CSS file, add a style to the bottom so it can fit their needs, save the file, and test the application. Unused CSS is one of the issues on the web (with images at the forefront of it all number).

Over time, this overgrown design file (or files) grows into something unmanageable - a large file full of unused CSS for one page. However, once we start using them, we add more CSS to the payload, making a web page swell in size. Luckily, we have CSS frameworks like Bootstrap and Foundation to help us build these websites.
While there are some designers in the industry, design is not a developer's strong suit (I know.I'm a developer, but we keep trying). For developers who build websites, they focus on functionality right out of the gate get the project working with HTML, add a JavaScript framework, and then sprinkle in some CSS to put lipstick on the pig.
