User Level: 

The Asset Injector module is a sophisticated contributed module that provides a permitted user with the ability to quickly apply both CSS and JavaScript overrides.

Keep in mind that changes in both CSS and JavaScript can result in undesirable results therefore, in our Drupal 8 distribution, the Site-Builder is the only role that is permitted to use the Asset Injector. If you're a Site-Builder who is not experienced with CSS and/or JavaScript, you'll want to keep your experiments confined to a development site.

Additionally, awareness and implementation of OSU's Brand Guidelines is especially important in regards to style overrides created with the CSS Injector. The OSU color palette has been carefully selected to both look good and to be accessible. For specific information regarding the color palette please see the Colors section of the Brand Guideline.
