http://lucasdebelder.be/googledoodle/ 这是一个实时版本。
因此,你可以在门户网站上看到它周围有一个发光,box-shadow;
我希望它能够开启和关闭所以它有点感觉更真实,我添加了transition: box-shadow ease-in-out;
但是它只在开始时,页面加载后才开始,然后继续发光。
这是相关代码。 (portaal_links表示左侧门户,rechts表示正确,它是荷兰语)
HTML:
<div class="portaal portaal_links"></div>
<div class="portaal portaal_rechts"></div>
CSS:
/*portaal general*/
.portaal {
position: absolute;
width: 100px;
height: 200px;
border-radius: 50px / 100px;
bottom: 315px;
}
/*portaal left*/
.portaal_links {
background: radial-gradient(ellipse at center, #1e5799 0%,#2989d8 50%,#207cca 51%,#7db9e8 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
transition: box-shadow ease-in-out;
transition-delay: 1s;
transition-duration: 1s;
box-shadow: 0 0 55px #57B6FF;
opacity: 0.75;
left: 50px;
}
.portaal_rechts {
background: radial-gradient(ellipse at center, rgba(243,197,189,1) 0%,rgba(232,108,87,1) 50%,rgba(234,40,3,1) 51%,rgba(255,102,0,1) 75%,rgba(199,34,0,1) 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
box-shadow: 0 0 55px #FF6600;
opacity: 0.55;
left: 750px;
}
