How to change background of 1 row in Yii2 Gridview - css

Question

I'm working with Yii 2, and it's grid view to show information.
Now, my problem is that whenever a user scans two identical serial numbers and/or mac addresses, it should highlight the row (change color to red), and show some error sign or whatever.

What I want it to look like:
I'm new to Yii2 and don't exactly know how they do it with the grid view. I've been researching on this specific problem but couldn't find anything.
Code for Gridview
<?= GridView::widget([
'id' => 'scan-batch-grid',
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
['class' => 'yii\grid\CheckboxColumn'],
[
'attribute' => 'product_ID',
'value' => 'product.name'
],
'SN',
'MAC',
[
'class' => 'yii\grid\ActionColumn',
'urlCreator' => function ($action, $model, $key, $index) {
return Url::to(['scan-batch/view', 'id' => $key, 'scan' => $model->scan_batch_ID]);
},
'buttons' => [
'update' => function ($url, $model, $key) {
return '';
},
'delete' => function ($url, $model, $key) {
return '';
},
],
],
],
]); ?>
EDIT
I only want to know how to change the color of only one row.

Simply add rowOptions to your gridview.
<?= GridView::widget([
'id' => 'scan-batch-grid',
'dataProvider' => $dataProvider,
'rowOptions'=>function($model){
if($a == $b){
return ['class' => 'danger'];
}
},

Thanks for posting your answer Paramone. Worked great.
Here is my implementation:
<?= GridView::widget([
'dataProvider' => $dataProvider,
'rowOptions' => function ($model) {
if ($model->name == 'test') {
return ['class' => 'info'];
}
},
