Otherwise, an element linked to a certain page can appear in the code of your style sheet without it playing any role for the page in question. For example, additional style sheet code that is added to a site for mobile and tablet users will not be useful for users who access your website through computers, and vice versa. In this case, none of these codes are completely useless because they can serve the internet for a specific audience. But when you add a style sheet to your website, but decide on a more specific design, it’s likely that some CSS code will remain useless. Obviously, in addition to the code related to the new design that you have chosen to keep, the code from the old style sheet will remain a burden for the site. A common case of generating unused CSS is when website owners decide to remove a feature, but forget to also remove the CSS it’s built on. For example, if you’ve ever used frameworks like Bootstrap, you should notice that they usually come with dozens of CSS styles that you probably don’t need. The most serious consequence of unnecessary CSS codes is that they cause pages to load more and more slowly. Since unused CSS is added to style sheets, this increases the overall file size. As a result, this significantly slows down response times and causes content to render on your webpage first.
With impressive speed, JitBit’s Unused CSS tool can crawl through all of your pages to show you the result of its work. In the diagnostic result, we can see that the detected selectors line up according to one category one after the other. For example, the selectors relating to the images find themselves aligned one after the other, then come the selectors of another category. A small flaw of the tool is that when you fill in the address of your site without htts, Unused CSS from JitBit finds the address invalid. We can consider this as a remarkable limit of Unused CSS, because novices will certainly not be used to typing their website address directly with the mention https//. For example, when I typed twaino.com in the reserved bar, you can notice that the tool tells me that my address is invalid. 
However, you will necessarily have to write the address of your website starting with https or http so that JitBit’s Unused CSS can take it into account. Although JitBit’s Unused CSS is a new tool in development, it is quite fast and efficient enough to serve its purpose. Currently no special conditions are required to enjoy the best features of this tool. This would mean that you don’t even need to register to use JitBit’s Unused CSS, as there isn’t a registration option either. It is not known whether certain terms of use will be enforceable thereafter. In any case, Unused CSS remains a good option if you feel the need to lighten up your website in order to improve page loading speed.
