That means sometimes it may be difficult to follow this guide to the letter; it means you will definitely run into exceptions, where following the guide is difficult to impossible without outsized effort. In those cases, you may work with your reviewers and maintainers to identify an approach that does not fit these rules. Please endeavor to limit these cases. + ### Utility Classes -As part of the effort for [cleaning up our CSS and moving our components into `gitlab-ui`](https://gitlab.com/groups/gitlab-org/-/epics/950) -led by the [GitLab UI WG](https://gitlab.com/gitlab-com/www-gitlab-com/-/merge_requests/20623) we prefer the use of utility classes over adding new CSS. However, complex CSS can be addressed by adding component classes. +In order to reduce the generation of more CSS as our site grows, prefer the use of utility classes over adding new CSS.
