教你用html+css实现炫光倒影按钮
话不多,先看效果:
实现过程(完整源码在最后):
1 老样子,定义基本样式:
*{ margin: 0; padding: 0; box-sizing: border-box; font-family: 'fangsong'; } body{ height: 100vh; display: flex; align-items: center; justify-content: center; background-color: rgb(0, 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 item1"> aurora <span></span> <span></span> <span></span> <span></span> </a> <a href="#" class="item item2"> aurora <span></span> <span></span> <span></span> <span></span> </a> <a href="#" class="item item3"> 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: 50px; width: 300px; height: 80px; text-align: center; line-height: 80px; text-transform: uppercase; text-decoration: none; font-size: 35px; letter-spacing: 5px; color: aqua; overflow: hidden; -webkit-box-reflect: below 1px 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 0 5px aqua, 0 0 75px aqua, 0 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(1){ position: absolute; left: -100%; width: 100%; height: 3px; background-image: linear-gradient(to left,aqua ,transparent); animation: shang 1s linear infinite; } @keyframes shang{ 0%{ left:-100%; } 50%,100%{ left:100%; } }
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(2){ position: absolute; top: -100%; right: 0; width: 3px; height: 100%; background-image: linear-gradient(to top,aqua ,transparent); animation: you 1s linear infinite; animation-delay: 0.25s; } @keyframes you{ 0%{ top:-100%; } 50%,100%{ top:100%; } } .item span:nth-of-type(3){ position: absolute; right: -100%; bottom: 0; width: 100%; height: 3px; background-image: linear-gradient(to right,aqua ,transparent); animation: xia 1s linear infinite; animation-delay: 0.5s; } @keyframes xia{ 0%{ right:-100%; } 50%,100%{ right:100%; } } .item span:nth-of-type(4){ position: absolute; bottom: -100%; left: 0; width: 3px; height: 100%; background-image: linear-gradient(to bottom,aqua ,transparent); animation: zuo 1s linear infinite; animation-delay: 0.75s; } @keyframes zuo{ 0%{ bottom:-100%; } 50%,100%{ bottom:100%; } }
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:
.item1{ filter: hue-rotate(100deg); } .item3{ filter: hue-rotate(250deg); }
filter: hue-rotate(100deg); 用色相旋转,这样不管背景还是阴影颜色都变了。
