1.09 MB in Style.css

I was looking at the files that the theme loads, and there is one exceptionally big the Style.css. 1.09MB is way to much, and the actual theme only uses 10% of the entire file. Any way to reduce this file other than manually going and deleting all the unwanted css?

You can minify the CSS using a tool like this https://www.seocentro.com/tools/online/minify-css.html. Just download the style.css file and copy everything inside it and paste in the box provided in the link above. Click submit and once the code is minified, copy the result and paste it in the downloaded file to replace the code inside it. Just click save and re-upload the file inside the newspaper theme folder and overwrite the original one.
