Question

I am using CSS reset you can find here : https://meyerweb.com/eric/tools/css/reset/

之间的CSS区别

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;
}

这里是问题：

在图像上，您可以在“取消”按钮下看到空白行。

我的问题是：应该使用哪个CSS属性使“基于标签的按钮”的大小与“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，而没有空白行。）

Answer 1

在我们没有明确添加line-height属性的情况下，您特别在这里缺少height属性。参见下面的代码片段，我还在顶部添加了重置CSS代码（已应用的内容）

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

Answer 2

首先，您的大多数CSS是相同的，因此只需要编写一次即可。

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

第三，如@Paulie_D <buttons>和<a>标签（链接）所述，它们不是一回事。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>

标签<a> and tag <input/>
