Figcaption过渡bug（Mozilla，Edge，IE）

Question

我有一些图片，:hover效果figcaption translateY应该figcaption，在Chrome上效果很好，但在其他浏览器上显示的是 <div class="col-md-4 col-sm-6 col-xs-12"> <figure> <img src="img/hidrau.png" alt="Hidraurio Mangueiras Hidraulicas" class="img-responsive"> <figcaption> <a href="http://hidrauriomangueiras.com.br" target="_blank"><button >Visitar</button></a> <a href="https://github.com/tiagosilveiraa/hidraurio" target="_blank"><button >Github</button></a> </figcaption> </figure> </div> 默认你怎么看下面。哪里我错了？如果您想亲眼看到我的网站，我的网站即播出：https://tiagosilveiraa.github.io
