Why is the red logo displayed in the NavBar?

Question

Yii

I've been studying YII2 for a couple of weeks, I ran into such a problem

here is the code
NavBar::begin([
'brandLabel' => ' ',
'brandUrl' => Yii::$app->homeUrl,
'options' => [
'class' => 'navbar-inverse navbar-fixed-top',
],
]);

Well, because there is no picture on the path that you set. Yii has nothing to do with it. 90% sure. But only your code is clumsily inserted and there is no link to the result. html what turned out as a result?
