复制即用！纯htmlcss写的炫酷input输入框

一般我们写css样式都要用样式库，但是嫌麻烦，如果能找到现成的内容复制上去就很香了，下文是笔者觉得好看的纯html&css写的样式，可以直接复制到Vue等内，十分方便。

input组件

1）

下面这个很推荐，优秀的动画

<div class="form-control">
    <input type="value" required="">
    <label>
        <span style="transition-delay:0ms">U</span><span style="transition-delay:50ms">s</span><span style="transition-delay:100ms">e</span><span style="transition-delay:150ms">r</span><span style="transition-delay:200ms">n</span><span style="transition-delay:250ms">a</span><span style="transition-delay:300ms">m</span><span style="transition-delay:350ms">e</span>
    </label>
</div>

.form-control {
  position: relative;
  margin: 20px 0 40px;
  width: 190px;
}

.form-control input {
  background-color: transparent;
  border: 0;
  border-bottom: 2px #fff solid;
  display: block;
  width: 100%;
  padding: 15px 0;
  font-size: 18px;
  color: #fff;
}

.form-control input:focus,
.form-control input:valid {
  outline: 0;
  border-bottom-color: lightblue;
}

.form-control label {
  position: absolute;
  top: 15px;
  left: 0;
  pointer-events: none;
}

.form-control label span {
  display: inline-block;
  font-size: 18px;
  min-width: 5px;
  color: #fff;
  transition: 0.3s cubic-bezier(0.68, -0.55, 0.265, 1.55);
}

.form-control input:focus+label span,
.form-control input:valid+label span {
  color: lightblue;
  transform: translateY(-30px);
}

2）

这个也不错

选中后：

<input placeholder="Enter your text..." class="input" name="text" type="text">

.input {
  background-color: #212121;
  max-width: 190px;
  height: 40px;
  padding: 10px;
  /* text-align: center; */
  border: 2px solid white;
  border-radius: 5px;
  /* box-shadow: 3px 3px 2px rgb(249, 255, 85); */
}

.input:focus {
  color: rgb(0, 255, 255);
  background-color: #212121;
  outline-color: rgb(0, 255, 255);
  box-shadow: -3px -3px 15px rgb(0, 255, 255);
  transition: .1s;
  transition-property: box-shadow;
}

下面这两个是简约商务风

html:

<div class="input-group">
    <label class="label">Email address</label>
    <input autocomplete="off" name="Email" id="Email" class="input" type="email">
    <div></div></div>

css:

.input {
  max-width: 190px;
  height: 44px;
  background-color: #05060f0a;
  border-radius: .5rem;
  padding: 0 1rem;
  border: 2px solid transparent;
  font-size: 1rem;
  transition: border-color .3s cubic-bezier(.25,.01,.25,1) 0s, color .3s cubic-bezier(.25,.01,.25,1) 0s,background .2s cubic-bezier(.25,.01,.25,1) 0s;
}

.label {
  display: block;
  margin-bottom: .3rem;
  font-size: .9rem;
  font-weight: bold;
  color: #05060f99;
  transition: color .3s cubic-bezier(.25,.01,.25,1) 0s;
}

.input:hover, .input:focus, .input-group:hover .input {
  outline: none;
  border-color: #05060f;
}

.input-group:hover .label, .input:focus {
  color: #05060fc2;
}

4）

html

<input type="password" name="text" class="input" pattern="\d+" placeholder="Numbers only or shake">

.input {
  max-width: 190px;
  padding: 12px;
  border: none;
  border-radius: 4px;
  box-shadow: 2px 2px 7px 0 rgb(0, 0, 0, 0.2);
  outline: none;
  color: dimgray;
}

.input:invalid {
  animation: justshake 0.3s forwards;
  color: red;
}

@keyframes justshake {
  25% {
    transform: translateX(5px);
  }

  50% {
    transform: translateX(-5px);
  }

  75% {
    transform: translateX(5px);
  }

  100% {
    transform: translateX-(5px);
  }
}

5）

选中后

<div class="inputbox">
    <input required="required" type="text">
    <span>Username</span>
    <i></i>
</div>

.inputbox {
  position: relative;
  width: 196px;
}

.inputbox input {
  position: relative;
  width: 100%;
  padding: 20px 10px 10px;
  background: transparent;
  outline: none;
  box-shadow: none;
  border: none;
  color: #23242a;
  font-size: 1em;
  letter-spacing: 0.05em;
  transition: 0.5s;
  z-index: 10;
}

.inputbox span {
  position: absolute;
  left: 0;
  padding: 20px 10px 10px;
  font-size: 1em;
  color: #8f8f8f;
  letter-spacing: 00.05em;
  transition: 0.5s;
  pointer-events: none;
}

.inputbox input:valid ~span,
.inputbox input:focus ~span {
  color: #45f3ff;
  transform: translateX(-10px) translateY(-34px);
  font-size: 0,75em;
}

.inputbox i {
  position: absolute;
  left: 0;
  bottom: 0;
  width: 100%;
  height: 2px;
  background: #45f3ff;
  border-radius: 4px;
  transition: 0.5s;
  pointer-events: none;
  z-index: 9;
}

.inputbox input:valid ~i,
.inputbox input:focus ~i {
  height: 44px;
}

点击后变宽，十分简约大气

<input type="text" name="text" placeholder="Search 'UIverse'" class="input">

.input[type = "text"] {
  display: block;
  color: rgb(34, 34, 34);
  background: linear-gradient(142.99deg, rgba(217, 217, 217, 0.63) 15.53%, rgba(243, 243, 243, 0.63) 88.19%);
  box-shadow: 0px 12px 24px -1px rgba(0, 0, 0,0.18);
  border-color: rgba(7, 4, 14, 0);
  border-radius: 50px;
  block-size: 20px;
  margin: 7px auto;
  padding: 18px 15px;
  outline: none;
  text-align: center;
  width: 200px;
  transition: 0.5s;
}

.input[type = "text"]:hover {
  width: 240px;
}

.input[type = "text"]:focus {
  width: 280px;
}

这个很有意思

点击其中一个会翻滚放大

<input type="text" name="text" class="input">
<input type="text" name="text" class="input">
<input type="text" name="text" class="input">

.input {
  max-width: 190px;
  width: 40px;
  height: 40px;
  outline: none;
  margin: 5px;
  transition: .5s;
  border: none;
  border-radius: 10px;
  padding: 10px;
  text-align: center;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
  transform: rotate(90deg);
}

input:focus {
  width: 150px;
  transform: rotate(0);
}
