实现过程(完整源码在最后):
1 老样子,定义基本样式:
*{
margin:;
padding:;
box-sizing: border-box;
font-family: 'fangsong';
}
body{
height:vh;
display: flex;
align-items: center;
justify-content: center;
background-color: rgb(, 0, 0);
}
font-family: ‘fangsong’; 仿宋字体。
display: flex;
align-items: center;
justify-content: center; flex布局,让按钮在屏幕居中。
2.定义基本标签:
<a href="#" class="item item">
aurora
<span></span>
<span></span>
<span></span>
<span></span>
</a>
<a href="#" class="item item">
aurora
<span></span>
<span></span>
<span></span>
<span></span>
</a>
<a href="#" class="item item">
aurora
<span></span>
<span></span>
<span></span>
<span></span>
</a>
3个a标签就对应3个按钮,每个按钮里4个span就是环绕按钮的4条边。
且都有个公共的选择器 .item 和 只属于自己的选择器。
3.定义每个按钮的基本样式:
.item{
position: relative;
margin:px;
width:px;
height:px;
text-align: center;
line-height:px;
text-transform: uppercase;
text-decoration: none;
font-size:px;
letter-spacing:px;
color: aqua;
overflow: hidden;
-webkit-box-reflect: belowpx linear-gradient( transparent,rgba(6, 133, 133,0.3));
}
text-align: center;文字对齐方式。
line-height: 80px; 字行高。
text-transform: uppercase; 字母为大写。
text-decoration: none; 去掉a标签默认下划线。
letter-spacing: 5px; 每个字符间的距离。
overflow: hidden;溢出隐藏。
-webkit-box-reflect: below 1px linear-gradient( transparent,rgba(6, 133, 133,0.3)); 这个属性能实现倒影效果。
4. 鼠标经过按钮样式改变:
.item:hover{
background-color: aqua;
box-shadow: 0 5px aqua,
0 75px aqua,
0 155px aqua;
color: black;
}
box-shadow:0 0 5px aqua,
0 0 75px aqua,
0 0 155px aqua; 阴影,写多行可以叠加更亮。
5.设置环绕按钮的4根线上面那条的样式:
.item span:nth-of-type(){
position: absolute;
left: -%;
width:%;
height:px;
background-image: linear-gradient(to left,aqua ,transparent);
animation: shangs linear infinite;
}
@keyframes shang{%{
left:-%;
}%,100%{
left:%;
}
}
position: absolute;
left: -100%; 定位在对应位置。
background-image: linear-gradient(to left,aqua ,transparent); 线性渐变颜色。
animation: shang 1s linear infinite; 动画属性,让它动起来。
5.以此类推,设置环绕按钮的其它3根样式:
.item span:nth-of-type(){
position: absolute;
top: -%;
right:;
width:px;
height:%;
background-image: linear-gradient(to top,aqua ,transparent);
animation: yous linear infinite;
animation-delay:.25s;
}
@keyframes you{%{
top:-%;
}%,100%{
top:%;
}
}
.item span:nth-of-type(){
position: absolute;
right: -%;
bottom:;
width:%;
height:px;
background-image: linear-gradient(to right,aqua ,transparent);
animation: xias linear infinite;
animation-delay:.5s;
}
@keyframes xia{%{
right:-%;
}%,100%{
right:%;
}
}
.item span:nth-of-type(){
position: absolute;
bottom: -%;
left:;
width:px;
height:%;
background-image: linear-gradient(to bottom,aqua ,transparent);
animation: zuos linear infinite;
animation-delay:.75s;
}
@keyframes zuo{%{
bottom:-%;
}%,100%{
bottom:%;
}
}
animation-delay: 0.75s; 动画延迟执行。每条线对应延迟一段时间,形成时间差,形成环绕效果。
6.给第一,第三个按钮设置其它颜色:
.item{
filter: hue-rotate(deg);
}
.item{
filter: hue-rotate(deg);
}
filter: hue-rotate(100deg); 用色相旋转,这样不管背景还是阴影颜色都变了。
