如何创建登录表单

步骤1）添加HTML：

在容器内添加图片并为每个字段添加输入（带有匹配的标签）。在它们周围包裹一个 <form> 元素来处理输入。您可以了解有关如何处理输入的更多信息PHP教程。

示例

<form action="action_page.html" method="post">
<div class="imgcontainer">
    <img src="img_avatar2.png" alt="Avatar" class="avatar">
</div>

<div class="container">
    <label for="uname"><b>Username</b></label>
    <input type="text" placeholder="Enter Username" name="uname" required>

    <label for="psw"><b>Password</b></label>
    <input type="password" placeholder="Enter Password" name="psw" required>

    <button type="submit">Login</button>
    <label>
      <input type="checkbox" checked="checked" name="remember"> Remember me
    </label>
</div>

<div class="container" style="background-color:#f1f1f1">
    <button type="button" class="cancelbtn">Cancel</button>
    <span class="psw">Forgot <a href="#">password?</a></span>
</div>
</form>

步骤2）添加CSS：

示例

/* Bordered form */
form {
border: 3px solid #f1f1f1;
}

/* Full-width inputs */
input[type=text], input[type=password] {
width: 100%;
padding: 12px 20px;
margin: 8px 0;
display: inline-block;
border: 1px solid #ccc;
box-sizing: border-box;
}

/* Set a style for all buttons */
button {
background-color: #04AA6D;
color: white;
padding: 14px 20px;
  margin: 8px 0;
border: none;
cursor: pointer;
width: 100%;
}

/* Add a hover effect for buttons */
button:hover {
  opacity: 0.8;
}

/* Extra style for the cancel button (red) */
.cancelbtn {
  width: auto;
  padding: 10px 18px;
  background-color: #f44336;
}

/* Center the avatar image inside this container */
.imgcontainer {
text-align: center;
margin: 24px 0 12px 0;
}

/* Avatar image */
img.avatar {
width: 40%;
border-radius: 50%;
}

/* Add padding to containers */
.container {
padding: 16px;
}

/* The "Forgot password" text */
span.psw {
float: right;
padding-top: 16px;
}

/* Change styles for span and cancel button on extra small screens */
@media screen and (max-width: 300px) {
span.psw {
    display: block;
    float: none;
  }
  .cancelbtn {
    width: 100%;
  }
}

      <span class="psw">Forgot <a href="#">password?</a></span>
    </div>
</form>
</div>

步骤2）添加CSS：

  height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
padding-top: 60px;
}

/* Modal Content/Box */
.modal-content {
background-color: #fefefe;
margin: 5px auto; /* 15% from the top and centered */
border: 1px solid #888;
  width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
  /* Position it in the top right corner outside of the modal */
position: absolute;
right: 25px;
top: 0;
  color: #000;
  font-size: 35px;
  font-weight: bold;
}

/* Close button on hover */
.close:hover,
.close:focus {
color: red;
  cursor: pointer;
}

/* Add Zoom Animation */
.animate {
  -webkit-animation: animatezoom 0.6s;
animation: animatezoom 0.6s
}

@-webkit-keyframes animatezoom {
from {-webkit-transform: scale(0)}
to {-webkit-transform: scale(1)}
}

@keyframes animatezoom {
from {transform: scale(0)}
to {transform: scale(1)}
}
