Code excerpts:

• File: report.php

120: echo html_writer::start_div('card mb-4');
121: echo html_writer::start_div('card-body');

• File: report.php

127: echo html_writer::start_div('form-group mr-3 mb-2');
128: echo html_writer::label(get_string('user') . ': ', 'userid', true, ['class' => 'mr-2']);

• File: report.php

225: if (empty($signals)) {
226:     echo html_writer::div(get_string('report:nosignals', 'local_agentdetect'), 'alert alert-info');
227: } else {
