标签<a>和标签<input>之间的 CSS 区别

Question

我正在使用CSS重置，您可以在这里找到：https://meyerweb.com/eric/tools/css/reset/

这是HTML代码：

<input class="submitForm" type="submit" value="Confirm" />
<a class="cancelForm" href="{{ path('my_path') }}">Cancel</a>

这是CSS代码：

.submitForm {
text-decoration: none;
font-family: "Aero Matics", sans-serif;
color: #FFFFFF;
font-size: 20px;
padding: 20px;
background-color: #65BCF1;
border: 0px none;
font-weight:bold;
float:right;
cursor: pointer;
}
.cancelForm {
text-decoration: none;
font-family: "Aero Matics", sans-serif;
color: #FFFFFF;
font-size: 20px;
padding: 20px;
background-color: #ff9667;
border: 0px none;
font-weight:bold;
float:left;
}

问题是：

在图像上，您可以在"取消"按钮下看到一条空行。

我的问题是：我应该使用哪个CSS属性来使我的"基于标记<a>的按钮"与"确认"按钮的大小完全相同？(我希望按钮从相同的高度开始，并完全填充到页面底部，没有空行(。

当我们没有显式添加height属性时，这里特别缺少line-height属性。请参阅我在重置css代码顶部添加的以下片段，您已经应用了这些代码：

<input class="submitForm" type="submit" value="Confirm" />
<a class="cancelForm" href="{{ path('my_path') }}">Cancel</a>

首先，大多数CSS都是一样的，所以只需要写一次。

第二：添加display: inline-block可以使margin和padding正常工作。

第三，正如@Paulie_D所说，<buttons>和<a>标签(链接(不是一回事。阅读他们建议的文章。

.submitForm,
.cancelForm {
background-color: #65BCF1;
border: 0px none;
color: #FFFFFF;
cursor: pointer;
display: inline-block;
font-family: "Aero Matics", sans-serif;
font-size: 20px;
font-weight:bold;
margin: 0;
padding: 20px;
text-decoration: none;
}
.cancelForm {
background-color: #ff9667;
}

<input class="submitForm" type="submit" value="Confirm" />
<a class="cancelForm" href="{{ path('my_path') }}">Cancel</a>
