## 如何使用CSS创建联系表单
|
||
|
||
首先，我们创建HTML元素 - 用于消息的名字，姓氏，电子邮件和文本区域的输入字段。
|
||
|
||
稍后我们应用CSS样式以使表单在视觉上吸引人。
|
||
|
||
### HTML部分
|
||
|
||
HTML部分有一个带有类`container`的div，标题为`h3` “ **Contact Form** ”
|
||
|
||
名称为**contact\_form**的表单包含以下输入字段：
|
||
|
||
* 名字
|
||
* 姓
|
||
* 电子邮件
|
||
* 信息
|
||
|
||
带有班级`center`的div，用于对齐项目中心。 `input`类型`submit`以提交表单。 在提交时检查文本字段中的`required`属性的值。
|
||
|
||
```html
|
||
|
||
<div class="container">
|
||
<h3>Contact Form</h3>
|
||
<form action="#" name="contact_form">
|
||
<label for="first_name">First Name</label>
|
||
<input name="first_name" type="text" required placeholder="John"/>
|
||
<br>
|
||
<label for="last_name">Last Name</label>
|
||
<input name="last_name" type="text" required placeholder="Doe"/>
|
||
<br>
|
||
<label for="email">Email</label>
|
||
<input name="email" type="email" required placeholder="you@domain.com"/>
|
||
<br>
|
||
<label for="message">Message</label><br>
|
||
<textarea name="message" cols="30" rows="10" placeholder="Enter your message here ..." required> </textarea>
|
||
<div class="center">
|
||
<input type="submit" value="Submit">
|
||
</div>
|
||
</form>
|
||
</div>
|
||
```
|
||
|
||
### CSS部分
|
||
|
||
```css
|
||
/* Importing the Roboto font from Google Fonts. */
|

@import url("https://fonts.googleapis.com/css?family=Roboto:400");

input[type=text]:focus,input[type=email]:focus, textarea:focus {

border: 1px solid green;
|
||
}
|
||
|

|

input[type=submit]:focus {
|

background: #A5D6A7;
|
||
color: whitesmoke;
|
||
}
|
||
|
||
/* Style 'hover' property */
|
||
input[type=submit]:hover {
|
||
background: #2196F3;
|
||
}
|
||
|
||
/* Align items to center of the 'div' with the class 'center' */
|
||
.center {
|
||
text-align: center;
|
||
}
|
||
```
