设置input 中的datetime-local 的宽度

你可以使用CSS来设置`datetime-local`的宽度。例如：

input[type="datetime-local"] {
  width: 200px; /*设置你想要的宽度*/
}

你可以将`width`的值设置为适合你的设计的大小。如果你想为所有的表单元素设置相同的宽度，你可以使用通用选择器。

input, select, textarea {
  width: 200px;
}

这将为所有的`input`,`select`和`textarea`元素设置相同的宽度。

input type=datetime-local

<input type="datetime-local"> is an HTML input type that allows users to select both date and time values. It provides a graphical interface for selecting dates and times in a specific format.

When a user interacts with the input field, a date and time picker will be displayed, allowing them to choose a specific date and time. The selected value will be returned in the format specified by the input's attributes.

Here's an example of how you can use the `<input type="datetime-local">` in HTML:

<label for="meeting-time">Choose a meeting date and time:</label>
<input type="datetime-local" id="meeting-time" name="meeting-time">

In this example, the `id` attribute is used to uniquely identify the input field, and the `name` attribute specifies the name of the input field when it is submitted to the server.

Please note that the availability and appearance of the date and time picker may vary depending on the user's device and browser.

datetime-local是HTML5中的一种表单元素类型，用于输入日期和时间。但是在Firefox桌面浏览器中不支持该输入类型，需要使用polyfill进行兼容处理。如果想要在日期输入框中设置默认值，可以在input标签中使用value属性来设置。<<引用>> <<引用>>
