Prerequisites

• [x] The issue still exists against the latest master branch of yii2-detail-view.
• [x] This is not an usage question. I confirm having gone through and read the documentation and demos.

• [ ] I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

1. Go to BS3 Detail View Demo
2. Find the Delete Button

Expected behavior and actual behavior

When I follow those steps, I see... nothing because the a-tag-buttons are rendered in the same color as the panel background, if you hover of it it isvisible. The BS4 version has the css class ".card .kv-action-btn" but BS3 doesnt add card. I was expecting... to see the button
