html - 使用 CSS3 搜索框时遇到问题

Question

我正在使用这个预编码的 css3 搜索框，但它对我不起作用。

CSS:

.cf:before, .cf:after{ 
.cf:after{
    clear:both;
}

.cf{
    zoom:1;
} 

/* Form wrapper styling */
.form-wrapper {
    width: 450px;
    padding: 15px;
    margin:50px auto;
    background:rgb(7,131,71);
    background: rgba(0,0,0,.2);
    border-radius: 10px;
    box-shadow: 0 1px 1px rgba(0,0,0,.4) inset, 0 1px 0 rgba(255,255,255,.2);
}

/* Form text input */

.form-wrapper input {
    width: 330px;
    height: 20px;
    padding: 10px 5px;
    float: left;   
    font: bold 15px 'lucida sans', 'trebuchet MS', 'Tahoma';
    border: 0;
    background: #eee;
    border-radius: 3px 0 0 3px;     
}

.form-wrapper input:focus {
    outline: 0;
    background: #fff;
    box-shadow: 0 0 2px rgba(0,0,0,.8) inset;
}

.form-wrapper input::-webkit-input-placeholder {
   color: rgb(7,131,71);
   font-weight: normal;
   font-style: italic;
}

.form-wrapper input:-moz-placeholder {
    color: rgb(7,131,71);
    font-weight: normal;
    font-style: italic;
}

.form-wrapper input:-ms-input-placeholder {
    color: rgb(7,131,71);
    font-weight: normal;
    font-style: italic;
}   

/* Form submit button */
.form-wrapper button {
    overflow: visible;
    position: relative;
    float: right;
    border: 0;
    padding: 0;
    cursor: pointer;
    height: 40px;
    width: 110px;
    font: bold 15px/40px 'lucida sans', 'trebuchet MS', 'Tahoma';
    color: #fff;
    text-transform: uppercase;
    background: rgb(7,131,71);
    border-radius: 0 3px 3px 0;     
    text-shadow: 0 -1px 0 rgba(0, 0 ,0, .3);
}  

.form-wrapper button:hover{    
    background: #3A423B;
}  

.form-wrapper button:active,
.form-wrapper button:focus{  
    background: rgb(7,131,71);
    outline: 0;  
}

.form-wrapper button:before { /* left arrow */
    content: '';
    position: absolute;
    border-width: 8px 8px 8px 0;
    border-style: solid solid solid none;
    border-color: transparent rgb(7,131,71) transparent;
    top: 12px;
    left: -6px;
}

.form-wrapper button:hover:before{
    border-right-color: #3A423B;
}

.form-wrapper button:focus:before,
.form-wrapper button:active:before{
        border-right-color: rgb(7,131,71);
}     

.form-wrapper button::-moz-focus-inner { /* remove extra button spacing for Mozilla Firefox */
    border: 0;
    padding: 0;
}    

HTML:

<form class="form-wrapper cf">
<form method="get" action="https://encrypted.google.com/search" target="_top">
        <input type="text" name="q" placeholder="Search here..." required>
        <button type="submit">Charge!</button>
    </form> 

除了当我点击“充电!”时，一切似乎都正常。 (提交按钮)。什么都没发生。它不会像预期的那样通过谷歌搜索。帮忙？

Answer 1

您有两个表单标签。您需要关闭输入标签。我不知道 required 是干什么用的，但这行得通:

<form class="form-wrapper cf" method="get" action="https://encrypted.google.com/search" target="_top">
    <input type="text" name="q" placeholder="Search here..." required />
    <button type="submit">Charge!</button>
</form>
