[英]How to change the color of a placeholder option in a Select tag?
I am trying to change the color of the first option (Business Type) in a select tag to gray so it looks like placeholder text for a text field.我正在尝试将选择标签中第一个选项(业务类型)的颜色更改为灰色,使其看起来像文本字段的占位符文本。 I tried several things that did not work.
我尝试了几件不起作用的事情。 Is there any way this could be done simply with HTML and CSS?
有什么办法可以简单地用 HTML 和 CSS 来完成?
<select id="businesstype">
<option value="" disabled selected hidden>Business Type</option>
<option value="">Restaurant</option>
<option value="">Hotel</option>
<option value="">Café</option>
<option value="">Shop</option>
<option value="">Services Agency</option>
<option value="">NGO</option>
<option value="">Institution</option>
</select>
This should work:这应该有效:
#businesstype div[disabled] {
opacity: 0.5;
}

Target select to change the selected
color style.目标选择以更改
selected
颜色样式。
Then, target all options from this select to reset their inherited color.然后,定位此选择中的所有选项以重置其继承的颜色。
#businesstype { color: gray; } #businesstype option { color: black; }
<select id="businesstype"> <option value="" disabled selected hidden>Business Type</option> <option value="">Restaurant</option> <option value="">Hotel</option> <option value="">Café</option> <option value="">Shop</option> <option value="">Services Agency</option> <option value="">NGO</option> <option value="">Institution</option> </select>
option:disabled {
color: #000;
font-weight: bold;
}
Add required in select tag and do like在选择标签中添加 required 并喜欢
<select class="form-control form-item__element--select" required>
<option disabled value="">Business Type*</option>
<option value="">Restaurant</option>
<option value="">Hotel</option>
<option value="">Café</option>
In CSS在 CSS 中
.form-item__element--select [disabled] {
color: #DEDEDE;
font-weight: 600;
font-size: 16px;
}
.form-item__element--select:invalid {
color: #DEDEDE;
font-weight: 600;
font-size: 16px;
}
You can do it by just adding following css,你可以通过添加以下css来做到这一点,
#businesstype option[disabled]:first-child {
color: gray;
}
