这是一款CSS3发光搜索表单,利用CSS3的glow属性,设置0%和100%时的颜色样式,让其渐变,再配合有明显对比的背景,就能模拟出发光的效果了,下面是详细代码讲解加下载地址
先来看一下效果图:
图上的搜索框在被激活的时候会出现闪闪发光的特效。
下面我们来一起看看源代码。
HTML代码非常简单,一个文本框和一个提交按钮:
复制代码代码如下: <form action="" method=""> <input type="search" placeholder="What are you looking for?"> <button>Search</button> </form>
然后重点就是CSS3代码了,首先是对搜索框和搜索按钮的样式进行初始化,为了配合背景能出现发光的效果,我们对它们的样式作了如下设置:
复制代码代码如下: .webdesigntuts-workshop { background: #151515; height: 100%; position: absolute; text-align: center; width: 100%; } .webdesigntuts-workshop:before,.webdesigntuts-workshop:after { content: ''; display: block; height: 1px; left: 50%; margin: 0 0 0 -400px; position: absolute; width: 800px; } .webdesigntuts-workshop:before { background: #444; background: -webkit-linear-gradient(left, #151515, #444, #151515); background: -moz-linear-gradient(left, #151515, #444, #151515); background: -o-linear-gradient(left, #151515, #444, #151515); background: -ms-linear-gradient(left, #151515, #444, #151515); background: linear-gradient(left, #151515, #444, #151515); top: 192px; } .webdesigntuts-workshop:after { background: #000; background: -webkit-linear-gradient(left, #151515, #000, #151515); background: -moz-linear-gradient(left, #151515, #000, #151515); background: -o-linear-gradient(left, #151515, #000, #151515); background: -ms-linear-gradient(left, #151515, #000, #151515); background: linear-gradient(left, #151515, #000, #151515); top: 191px; } .webdesigntuts-workshop form { background: #111; background: -webkit-linear-gradient(#1b1b1b, #111); background: -moz-linear-gradient(#1b1b1b, #111); background: -o-linear-gradient(#1b1b1b, #111); background: -ms-linear-gradient(#1b1b1b, #111); background: linear-gradient(#1b1b1b, #111); border: 1px solid #000; border-radius: 5px; box-shadow: inset 0 0 0 1px #272727; display: inline-block; font-size: 0px; margin: 150px auto 0; padding: 20px; position: relative; z-index: 1; } .webdesigntuts-workshop input { background: #222; background: -webkit-linear-gradient(#333, #222); background: -moz-linear-gradient(#333, #222); background: -o-linear-gradient(#333, #222); background: -ms-linear-gradient(#333, #222); background: linear-gradient(#333, #222); border: 1px solid #444; border-radius: 5px 0 0 5px; box-shadow: 0 2px 0 #000; color: #888; display: block; float: left; font-family: 'Cabin', helvetica, arial, sans-serif; font-size: 13px; font-weight: 400; height: 40px; margin: 0; padding: 0 10px; text-shadow: 0 -1px 0 #000; width: 200px; } .ie .webdesigntuts-workshop input { line-height: 40px; } .webdesigntuts-workshop input::-webkit-input-placeholder { color: #888; } .webdesigntuts-workshop input:-moz-placeholder { color: #888; } .webdesigntuts-workshop input:focus { -webkit-animation: glow 800ms ease-out infinite alternate; -moz-animation: glow 800ms ease-out infinite alternate; -o-animation: glow 800ms ease-out infinite alternate; -ms-animation: glow 800ms ease-out infinite alternate; animation: glow 800ms ease-out infinite alternate; background: #222922; background: -webkit-linear-gradient(#333933, #222922); background: -moz-linear-gradient(#333933, #222922); background: -o-linear-gradient(#333933, #222922); background: -ms-linear-gradient(#333933, #222922); background: linear-gradient(#333933, #222922); 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; color: #efe; outline: none; } .webdesigntuts-workshop input:focus::-webkit-input-placeholder { color: #efe; } .webdesigntuts-workshop input:focus:-moz-placeholder { color: #efe; } .webdesigntuts-workshop button { background: #222; background: -webkit-linear-gradient(#333, #222); background: -moz-linear-gradient(#333, #222); background: -o-linear-gradient(#333, #222); background: -ms-linear-gradient(#333, #222); background: linear-gradient(#333, #222); -webkit-box-sizing: content-box; -moz-box-sizing: content-box; -o-box-sizing: content-box; -ms-box-sizing: content-box; box-sizing: content-box; border: 1px solid #444; border-left-color: #000; border-radius: 0 5px 5px 0; box-shadow: 0 2px 0 #000; color: #fff; display: block; float: left; font-family: 'Cabin', helvetica, arial, sans-serif; font-size: 13px; font-weight: 400; height: 40px; line-height: 40px; margin: 0; padding: 0; position: relative; text-shadow: 0 -1px 0 #000; width: 80px; } .webdesigntuts-workshop button:hover, .webdesigntuts-workshop button:focus { background: #292929; background: -webkit-linear-gradient(#393939, #292929); background: -moz-linear-gradient(#393939, #292929); background: -o-linear-gradient(#393939, #292929); background: -ms-linear-gradient(#393939, #292929); background: linear-gradient(#393939, #292929); color: #5f5; outline: none; } .webdesigntuts-workshop button:active { background: #292929; background: -webkit-linear-gradient(#393939, #292929); background: -moz-linear-gradient(#393939, #292929); background: -o-linear-gradient(#393939, #292929); background: -ms-linear-gradient(#393939, #292929); background: linear-gradient(#393939, #292929); box-shadow: 0 1px 0 #000, inset 1px 0 1px #222; top: 1px; }
然后就是利用glow属性,进行发光效果渲染,为了适应不同内核的浏览器,我们分别对其做了如下设置:
复制代码代码如下: @-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; } }
