html - 无法使占位符输入文本消失

Question

所以我有一个表单，我设法让所有占位符输入文本淡出，除了评论框，除非我定义评论框 input type="text"然后它得到与其他字段相同的设计。这是我的 contact-form-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:

您可以在以下链接中查看表格:www.walterbar.co.il 它位于页面的最底部，对于奇怪的语言，我深表歉意。

所以就像我说的，我想保留当前的设计，但让评论框(第四字段)内的文本像其他字段一样消失。它仅在我将输入类型定义为文本时才有效，但随后它会强制采用与其余字段相同的设计。 提前致谢!

根据我通过查看链接中的表格所理解的，您所说的已应用的占位符实际上设置为 textarea 的值，这就是为什么必须在输入数据之前将其删除的原因。 你试过下面的那个吗？

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