I recently purchased a bootstrap theme, and all the css for the theme is compiled. I have not worked with compiled css before, so I want to learn what the best practices are for editing the theme’s css?
This particular theme has compiled css for the main site, and then individual css for each page like “about us”, etc.
Unless you are experienced in bootstrap/less then the best course of action is simply to leave them completely alone. Just create a custom stylesheet and put your changes in there. If the theme or bootstrap is updated at a later date then you still have your custom css separate which you can apply and amend for the new version.
