将文本居中放在圆形按钮上

Question

我想创建一个带有文本的按钮圈链接,但我有问题将文本置于圈子按钮内.线高太大.对这个问题有什么建议吗？

这是代码:https://jsfiddle.net/hma443rL/

.btn-donate {
  background: #97c83e;
  text-align: center;
  width: 149px;
  height: 148px;
  border-radius: 100%;
  display: inline-block;
  font-size: 35px;
  line-height: 2.3;
  vertical-align:middle;
  color: white;
  font-weight: bold;
  text-decoration: none
}

<a href="" class="btn btn-donate">
  Donate <span>Us</span>
</a>

Flexbox可以做到这一点:

.btn-donate {
  background: #97c83e;
  text-align: center;
  width: 149px;
  height: 149px;
  border-radius: 100%;
  display: inline-flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  font-size: 35px;
  color: white;
  font-weight: bold;
  text-decoration: none
}

<a href="" class="btn btn-donate">Donate <span>Here</span></a>
