所以我不想使用“ Required”属性,但是如果我不把它放在那儿,它会完全弄乱我希望表单显示的方式。
那为什么要删除此更改呢?它的设置是这样,当您单击“电子邮件”时,它将移开,看起来像输入密码的那个。
这是我的html
<form action="./includes/login.inc.php" method="post">
<div class="group">
<input type="text" name="emailuid" required=""/><span class="highlight"></span><span class="bar"></span>
<label>Email</label>
</div>
<div class="group">
<input type="password" name="pwduid"/><span class="highlight"></span><span class="bar"></span>
<label>Password</label>
</div>
<div class="btn-box">
<button class="btn btn-submit" type="submit" name="login-submit">Sign in</button>
</div>
</form>
这是我的CSS样式(仅用于表单!)

font-size: 3em;

}
我只是很困惑为什么它强制我使用必填属性,我不想使用它,因为我做了一个php检查器来查看字段是否为空。这让我的外观看起来有些混乱。
感谢您的帮助。

TLDR; 更改此代码:
input:focus ~ label,
input:valid ~ label,
textarea:focus ~ label,
textarea:valid ~ label
{
top: -14px;
font-size: 12px;
color: #FF3B3F;
}
对此:
input:focus ~ label,
textarea:focus ~ label
{
top: -14px;
font-size: 12px;
color: #FF3B3F;
}
说明:
信不信由你,CSS样式可以应用于特别具有某些属性的元素,因此,应始终确保检查CSS中与这些属性相对应的伪类。示例:input:required {...}
对应于required
元素上的input
HTML属性。
为了使事情变得更加复杂,required
属性可以确定是否在该元素上激活了其他伪类,例如:valid
。因此,如果将元素设置为required
,但未正确填写该字段,则任何指定:invalid
伪类的CSS都会被自动激活。如果正确填写,则:valid
伪类CSS属性将生效。
答案 1 :(得分:1)
因此您的CSS中的input:valid ~ label
引起了问题。
试试这个:
form {
width: 320px;
margin: 45px auto;
}
.group {
position: relative;
margin: 45px 0;
}
input {
background: none;
color: #4F4F4F;
font-size: 18px;
padding: 10px 10px 10px 5px;
display: block;
width: 320px;
border: none;
border-radius: 0;
border-bottom: 1px solid #4F4F4F;
}
input:focus {
outline: none;
}
input:focus ~ label {
top: -14px;
font-size: 12px;
color: #FF3B3F;
}
input:focus ~ .bar:before {
width: 335px;
}
input[type="password"] {
letter-spacing: 0.3em;
}
label {
color: #4F4F4F;
font-size: 16px;
font-weight: normal;
