Yii2 Alert::widget registers css stylesheet in head, how to prevent it from doing so?

Question

Yii

I want to use the Alert widget, as shown in the Yii2 advanced template example - this widget is called in the layout before $content. The problem is that when this widget is launched, it registers in the system a style sheet - bootstrap.css, which comes after all my styles and overrides the styles that have already worked. The result is chaos. How can I make Alert::widget not register my bootstrap, but use only the styles that I set for it. Now, even if I set my styles for him, he still registers this boostrap. How competently to forbid it to him?

Answer 1

Write your own widget based on Alert, there are a couple of lines of code. Specifically, you just remove it from the run method
. But without bootstrap, it makes no sense, it essentially connects js and builds a layout for bootstrap.
