继续学习-CSS3页面美化之让页面动起来

继昨日的美化一轮以后，页面也是蛮好看的了。但是还缺乏些动态响应。今天带来的是CSS3的动态响应。由于CSS3对于动画和变形这一部分，某些浏览器支持不好（IE），所以这里仅仅是使用Chrome来写的，使用的前缀是-webkit-，效果还是蛮赞的。

话不多说，首先我们来改造按钮，让它在鼠标移动后加入动画效果。



当鼠标移入以后，会缓慢变化：



修改后的content a的样式为：

#content a{
font-family:Arial, Helvetica, Verdana, sans-serif;
font-size:1.65em;
text-transform:uppercase;
text-decoration:none;
background-color:#B01C20;
border-radius:8px;
color:white;
padding:3.8461538%;
float:left;
background: -webkit-linear-gradient(90deg, #B01C20 0%, #F15C60 100%);
margin-top:30px;
box-shadow:5px 5px 5px hsla(0, 0%, 26.6667%, 0.8);
text-shadow:0px 1px black;
border:1px solid #BFBFBF;
-webkit-transition-property: border, color, text-shadow;
-webkit-transition-duration: 2s, 3s, 8s;
-webkit-transition-timing-function:ease;
-webkit-transition-delay:0s;
}
#content a:hover{
border: 1px solid #000000;
color:#000000;
text-shadow: 0px 1px white;
}

这里还添加了hover样式，就是为了鼠标移入变换的。

其次，改造导航栏。让鼠标移入有更加绚烂的提示效果。



首先定义动画帧

@-webkit-keyframes warning {
0%{
text-shadow: 0px 0px 4px #000000;
}
50%{
text-shadow: 0px 0px 20px #000000;
}
100%{
text-shadow: 0px 0px 4px #000000;
}
}

然后在导航栏的a标签的hover加入这个动画

nav ul li a:hover{
-webkit-animation: warning 1.5s infinite ease-in;
//-webkit-animation-name: warning;
//-webkit-animation-duration: 1.5s;
//-webkit-animation-timing-function: ease;
//-webkit-animation-iteration-count: infinite;
//-webkit-animation-play-state: running;
//-webkit-animation-delay: 0s;
//-webkit-animation-fill-mode: none;
color:hsl(359, 99%, 40%);
}

注释掉的是分开的写法。

最后，我们让侧边栏的海报在网页载入完成后，抖动几下。



也是先加入关键帧：

@-webkit-keyframes swing {
0%{
-webkit-transform: rotate(3deg);
}
20%{
-webkit-transform: rotate(7deg);
}
60%{
-webkit-transform: rotate(10deg);
}
80%{
-webkit-transform: rotate(7deg);
}
100%{
-webkit-transform: rotate(3deg);
}
}

然后给a标签添加动画效果：

aside section a:nth-child(odd) img{
-webkit-transform: rotate(3deg);
-webkit-animation: swing 0.1s 5 ease-in;
}
aside section a:nth-child(even) img{
-webkit-transform: rotate(-3deg);
-webkit-animation: swing 0.1s 5 0.3s ease-in;
}

ok，这里给出全部CSS代码，便于大家交流。style.css：

@font-face {
font-family: 'BebasNeueRegular';
src:url('../fonts/BebasNeue-webfont.eot');
src:url('../fonts/BebasNeue-webfont.eot?#iefix') format('embedded-opentype'),
url('../fonts/BebasNeue-webfont.woff') format('woff'),
url('../fonts/BebasNeue-webfont.ttf') format('truetype'),
url('../fonts/BebasNeue-webfont.svg#BebasNeueRegular') format('svg');
font-weight:400;
}
@-webkit-keyframes warning {
0%{
text-shadow: 0px 0px 4px #000000;
}
50%{
text-shadow: 0px 0px 20px #000000;
}
100%{
text-shadow: 0px 0px 4px #000000;
}
}

@-webkit-keyframes swing {
0%{
-webkit-transform: rotate(3deg);
}
20%{
-webkit-transform: rotate(7deg);
}
60%{
-webkit-transform: rotate(10deg);
}
80%{
-webkit-transform: rotate(7deg);
}
100%{
-webkit-transform: rotate(3deg);
}
}
