A simple textarea in the settings, add one css class per row, then we use drupalSettings to get that array and equalise the blocks.</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <p>Do the work</p> <h3 id="summary-ui-changes">User interface changes</h3> <p>New theme setting item on appearance page</p> <h3 id="summary-api-changes">API changes</h3> <p>None</p> <h3 id="summary-data-model-changes">Data model changes</h3> <p>None</p>
