如何让我的按钮透明？我一直试图使用.btn-transparent,但似乎无法让它工作.按钮只是变灰了.

<!-- Search Button -->
<div class="container3">
<div class="btn-group ">
<button type="button" class="btn btn-primary-outline">SEARCH</button>
<button type="button" class="btn btn-primary-outline">
<span class="glyphicon glyphicon-menu-right"></span>
</button>
</div>
</div>
</p>
解决方法
将css设为.btn-primary-outline
