为表单添加下面的必要CSS样式:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 | .login-page { width: 360px; padding: 8% 0 0; margin: auto;}.form { position: relative; z-index: 1; background: #FFFFFF; max-width: 360px; margin: 0 auto 100px; padding: 45px; text-align: center; box-shadow: 0 0 20px 0 rgba(0, 0, 0, 0.2), 0 5px 5px 0 rgba(0, 0, 0, 0.24);}.form input { font-family: "Roboto", sans-serif; outline: 0; background: #f2f2f2; width: 100%; border: 0; margin: 0 0 15px; padding: 15px; box-sizing: border-box; font-size: 14px;}.form button { font-family: "Microsoft YaHei","Roboto", sans-serif; text-transform: uppercase; outline: 0; background: #4CAF50; width: 100%; border: 0; padding: 15px; color: #FFFFFF; font-size: 14px; -webkit-transition: all 0.3 ease; transition: all 0.3 ease; cursor: pointer;}.form button:hover,.form button:active,.form button:focus { background: #43A047;}.form .message { margin: 15px 0 0; color: #b3b3b3; font-size: 12px;}.form .message a { color: #4CAF50; text-decoration: none;}.form .register-form { display: none;}.container { position: relative; z-index: 1; max-width: 300px; margin: 0 auto;}.container:before, .container:after { content: ""; display: block; clear: both;}.container .info { margin: 50px auto; text-align: center;}.container .info h1 { margin: 0 0 15px; padding: 0; font-size: 36px; font-weight: 300; color: #1a1a1a;}.container .info span { color: #4d4d4d; font-size: 12px;}.container .info span a { color: #000000; text-decoration: none;}.container .info span .fa { color: #EF3B3A;}body { background: #76b852; /* fallback for old browsers */ background: -webkit-linear-gradient(right, #76b852, #8DC26F); background: -moz-linear-gradient(right, #76b852, #8DC26F); background: -o-linear-gradient(right, #76b852, #8DC26F); background: linear-gradient(to left, #76b852, #8DC26F); font-family: "Roboto", sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; } |
表单左右摇晃的效果使用CSS3 animation动画来实现:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | .shake_effect{ -webkit-animation-name: shake; animation-name: shake; -webkit-animation-duration: 1s; animation-duration: 1s;}@-webkit-keyframes shake { from, to { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } 10%, 30%, 50%, 70%, 90% { -webkit-transform: translate3d(-10px, 0, 0); transform: translate3d(-10px, 0, 0); } 20%, 40%, 60%, 80% { -webkit-transform: translate3d(10px, 0, 0); transform: translate3d(10px, 0, 0); }}@keyframes shake { from, to { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } 10%, 30%, 50%, 70%, 90% { -webkit-transform: translate3d(-10px, 0, 0); transform: translate3d(-10px, 0, 0); } 20%, 40%, 60%, 80% { -webkit-transform: translate3d(10px, 0, 0); transform: translate3d(10px, 0, 0); }} |
简单的对表单进行了一些验证 方法
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 | function check_login(){var name=$("#user_name").val();var pass=$("#password").val();if(name=="admin" && pass=="admin"){ alert("登录成功!"); $("#user_name").val(""); $("#password").val("");}else{ $("#login_form").removeClass('shake_effect'); setTimeout(function() { $("#login_form").addClass('shake_effect') },1); }}function check_register(){ var name = $("#r_user_name").val(); var pass = $("#r_password").val(); var email = $("r_email").val(); if(name!="" && pass=="" && email != "") { alert("注册成功!"); $("#user_name").val(""); $("#password").val(""); } else { $("#login_form").removeClass('shake_effect'); setTimeout(function() { $("#login_form").addClass('shake_effect') },1); }} |
