无法使占位符输入文本消失。

Question

所以我有一个表单，我设法使所有占位符输入文本淡出，除了注释框之外，除非我定义了注释框输入type=" text“，然后它得到了与其他字段相同的设计。这就是我的联系人表格-7插件中的内容：

<style>
input[type="email"]::-webkit-input-placeholder  {
  -webkit-transition: opacity 0.3s linear; 
  color: gray;
}

input[type="email"]:focus::-webkit-input-placeholder  {
  opacity: 0;
}
input[type="phone"]::-webkit-input-placeholder  {
  -webkit-transition: opacity 0.3s linear; 
  color: gray;
}

input[type="phone"]:focus::-webkit-input-placeholder  {
  opacity: 0;
}
}
input[type="text"]::-webkit-input-placeholder  {
  -webkit-transition: opacity 0.3s linear; 
  color: gray;
}

input[type="text"]:focus::-webkit-input-placeholder  {
  opacity: 0;
}

</style>
<center> 

<label for=".elementor-6 .elementor-element.elementor-element-5m0lukt .wpcf7 input[type="text"]"><input type=text text* your-name placeholder="שם" required id:name </input></label>

<label for= ".wpcf7-form-control.wpcf7-text.wpcf7-tel.wpcf7-validates-as-required.wpcf7-validates-as-tel* your-email"> <input type="phone" tel* tel-196 input placeholder="טלפון" id:phone required</input></label>

<label for=".wpcf7-form-control.wpcf7-text.wpcf7-email.wpcf7-validates-as-required.wpcf7-validates-as-email"]"><input type=email email* your-email placeholder="אימייל" ID:email </input></label>

[textarea details id:details class:details placeholder="ההודעה שלכם"]

[submit "דברו איתנו"]
</center>

这是相关的CSS：

您可以在下面的链接中看到表单：www.walterbar.co.il --它位于页面的最底部，我为这种奇怪的语言道歉。

所以就像我说的，我想保持当前的设计，但是让评论框(第四个字段)中的文本像其他字段一样消失。只有当我将输入类型定义为文本时，它才能工作，但随后它强制执行与其他字段相同的设计。提前感谢！

Answer 1

首先，所有input中的占位符都在placeholder属性中。但是，textarea中的内容在innerHTML中。您必须在placeholder属性内移动textarea的内容。

<textarea name="details" placeholder="ההודעה שלכם" cols="40" rows="10" class="wpcf7-form-control wpcf7-textarea details" id="details" aria-invalid="false"></textarea>

但是，这将扰乱您的css，并使textarea与您看到的所有input类似：

​

​

因此，您必须覆盖您的css基本上使它看起来像它的早期自我。在css中使用!important属性并添加以下内容：

#details.wpcf7-form-control.wpcf7-textarea.details {
    width: 40% !important;
    height: 150px !important;
    border-radius: 0 !important;
}

这应使预期的行为：

Answer 2

根据我通过查看链接中的表单所了解到的信息，您已经应用的占位符实际上被设置为textarea的值，这就是在输入数据之前必须删除它的原因。你试过下面那个吗？

<textarea id="details" class="details" placeholder="ההודעה שלכם"></textarea>
