Attach Stylesheet to custom 404 page

I created a custom 404 page using these instructions:

https://knowledge.hubspot.com/articles/kcs_article/cos-general/use-system-templates-to-customize-error-subscription-and-password-prompt-pages

When viewing the page in action (at a url that doesn’t exist such as http://northdallas.hubspotusergroups.com/asdf) the HubSpot icon on the right top of screen does not have the option to Edit Page. Therefore, I can’t get to Settings to attach my stylsheets.

Is there another way to attach my stylesheets?

Is there another way

Figured it out… Applied my styles globally. Apparently system pages are not treated like regular pages, hence I can’t click Edit Page when viewing it. Oh well.

If anyone knows how to create a 404 page that is the same as a regular page, please tell.

@therobert - Glad it’s working, you can mark your own answer as solved BTW :grinning_face_with_smiling_eyes:
