How to change background of 1 row in Yii2 Gridview

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.

Yii2 Gridview row by row css expression

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'];         }     },
