Installed with this:</p> <p>composer require drupal/gin_toolbar:^2.0 drupal/gin:^4.0</p> <p>And changed the Admin theme from my custom theme. I didn't like Gin so I changed it back to my theme. All of the colors and the layout out my theme were changed somehow.</p> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <p>Install Gin.<br> Change admin theme from my custom theme to Gin.<br> Change admin theme from Gin back to my custom theme.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>It is as if Gin is imposing its color setting and block layout and who knows what else onto the theme that was in effect before I changed the theme to Gin. I hope I will be able to restore my colors and layout from my production site.</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <h3 id="summary-ui-changes">User interface changes</h3> <p>Don't affect other themes with your theme!</p> <h3 id="summary-api-changes">API changes</h3> <h3 id="summary-data-model-changes">Data model changes</h3>
