html - 为什么我的 HTML 元素的大小没有改变

Question

我正在尝试更改“发送”按钮的大小，但它没有响应。我知道这应该是一个简单的修复，但我不确定发生这种情况的确切原因。我想知道是否有人可以帮助我。谢谢。

这是 CSS:

.send{
    border-radius: 20px;
    background-color: #00e699;
    font-weight: bold;
    color: white;
    position:relative;
    width: 80%;
    height: 80%;
    top: 50px; 
    left: 32%;   
}

这是包含“发送”按钮的 HTML

<div class="infocard">
      <div class = "col-md-12" >
        <h3 class="theName"></h3>
        <h3 class="theNum"></h3>
        <h3 class="theDate"></h3>

        <input type = "text" name = "Name" size = "30" class = "textBox" ng-model = "input" />
        <a href= "" style = "text-decoration: none; color: white;" class = "send" ng-click="passPrompt()">Send Message</a>
      </div>
    </div>

只需根据需要添加显示类型

.send{
    border-radius: 20px;
    background-color: #00e699;
    font-weight: bold;
    color: white;
    position:relative;
    width: 50%;
    height: 80%;
    top: 50px; 
    left: 32%;   
    display:block;
}

<div class="infocard">
      <div class = "col-md-12" >
        <h3 class="theName"></h3>
        <h3 class="theNum"></h3>
        <h3 class="theDate"></h3>

        <input type = "text" name = "Name" size = "30" class = "textBox" ng-model = "input" />
        <a href= "" style = "text-decoration: none; color: white;" class = "send" ng-click="passPrompt()">Send Message</a>
      </div>
    </div>
