如何使用CSS建立堆疊表單?


在堆疊表單中,輸入欄位、標籤和按鈕彼此疊加。當在不同的裝置上開啟帶有表單的網頁時,它將疊加。使用 <form> 元素在網頁上建立表單。讓我們瞭解如何使用CSS建立堆疊表單。

建立表單

使用 <form> 元素在網頁上建立表單。輸入欄位包括文字、密碼和重複密碼輸入型別。同時,登入和註冊按鈕也位於以下位置 -

<form>
   <label for="email"><b>Email</b></label>
   <input type="text" placeholder="Enter Email" name="email" required>
   <label for="psw"><b>Password</b></label>
   <input type="password" placeholder="Enter Password" name="psw" required>
   <label for="psw-repeat"><b>Repeat Password</b></label>
   <input type="password" placeholder="Repeat Password" name="psw-repeat" required>
   <hr>

   <button type="submit" class="registerbtn">Register</button>
   <div class="signin">
      <p>Already have an account? <a href="#">Sign in</a>.</p>
   </div>
</form>

設定表單樣式

使用max-width屬性設定最大寬度來設定表單樣式 -

form {
   padding: 16px;
   max-width: 800px;
   margin-left: 20%;
   background-color: rgb(255, 254, 195);
}

設定輸入欄位樣式

輸入欄位的寬度設定為100%。display屬性設定為inline-block -

input[type=text], input[type=password] {
   width: 100%;
   font-size: 20px;
   padding: 15px;
   margin: 5px 0 22px 0;
   display: inline-block;
   border: none;
   background: #f1f1f1;
}

註冊按鈕

使用 <button> 元素在網頁上建立一個註冊按鈕 -

<button type="submit" class="registerbtn">Register</button>

設定註冊按鈕樣式 -

.registerbtn {
   background-color: #4CAF50;
   color: white;
   font-size: 25px;
   padding: 16px 20px;
   margin: 8px 0;
   border: none;
   cursor: pointer;
   width: 100%;
   opacity: 0.9;
}

示例

以下是使用CSS建立堆疊表單的程式碼 -

<!DOCTYPE html>
<html>
<head>
   <style>
      body {
         font-family: Arial, Helvetica, sans-serif;
