css3發(fā)光搜索表單代碼分享

本篇內容介紹了“css3發(fā)光搜索表單代碼分享”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！

先來看一下效果圖：

圖上的搜索框在被激活的時候會出現閃閃發(fā)光的特效。

下面我們來一起看看源代碼。

HTML代碼非常簡單，一個文本框和一個提交按鈕：

代碼如下:

<form action="" method="">            
       <input type="search" placeholder="What are you looking for?">                
       <button>Search</button>
</form>

然后重點就是CSS3代碼了，首先是對搜索框和搜索按鈕的樣式進行初始化，為了配合背景能出現發(fā)光的效果，我們對它們的樣式作了如下設置：

代碼如下:

.webdesigntuts-workshop {
background: #151515;
height: 100%;
position: absolute;
text-align: center;
width: 100%;
}
.webdesigntuts-workshop:before,.webdesigntuts-workshop:after {

}

然后就是利用glow屬性，進行發(fā)光效果渲染，為了適應不同內核的瀏覽器，我們分別對其做了如下設置：

代碼如下:

@-webkit-keyframes glow {
0% {
border-color: #393;
box-shadow: 0 0 5px rgba(0,255,0,.2), inset 0 0 5px rgba(0,255,0,.1), 0 2px 0 #000;
}
100% {
border-color: #6f6;
box-shadow: 0 0 20px rgba(0,255,0,.6), inset 0 0 10px rgba(0,255,0,.4), 0 2px 0 #000;
}
}
@-moz-keyframes glow {
0% {
border-color: #393;
box-shadow: 0 0 5px rgba(0,255,0,.2), inset 0 0 5px rgba(0,255,0,.1), 0 2px 0 #000;
}
100% {
border-color: #6f6;
box-shadow: 0 0 20px rgba(0,255,0,.6), inset 0 0 10px rgba(0,255,0,.4), 0 2px 0 #000;
}
}</p> <p>@-o-keyframes glow {
0% {
border-color: #393;
box-shadow: 0 0 5px rgba(0,255,0,.2), inset 0 0 5px rgba(0,255,0,.1), 0 2px 0 #000;
}
100% {
border-color: #6f6;
box-shadow: 0 0 20px rgba(0,255,0,.6), inset 0 0 10px rgba(0,255,0,.4), 0 2px 0 #000;
}
}
@-ms-keyframes glow {
0% {
border-color: #393;
box-shadow: 0 0 5px rgba(0,255,0,.2), inset 0 0 5px rgba(0,255,0,.1), 0 2px 0 #000;
}
100% {
border-color: #6f6;
box-shadow: 0 0 20px rgba(0,255,0,.6), inset 0 0 10px rgba(0,255,0,.4), 0 2px 0 #000;
}
}
@keyframes glow {
0% {
border-color: #393;
box-shadow: 0 0 5px rgba(0,255,0,.2), inset 0 0 5px rgba(0,255,0,.1), 0 2px 0 #000;
}
100% {
border-color: #6f6;
box-shadow: 0 0 20px rgba(0,255,0,.6), inset 0 0 10px rgba(0,255,0,.4), 0 2px 0 #000;
}
}
