<!--主要样式-->
<style type="text/css">
* {
margin: 0;
padding: 0;
}
/*hovertreenav styles*/
.hovertreenav ul {
background: white;
border-top: 6px solid hsl(180, 40%, 60%);
width: 200px;
margin: 5em auto;
}

.hovertreenav ul li {
list-style-type: none;
/*relative positioning for list items along with overflow hidden to contain the overflowing ripple*/
position: relative;
overflow: hidden;
}

.hovertreenav ul li a {
font: normal 14px/28px Montserrat;
color: hsl(180, 40%, 40%);
display: block;
padding: 10px 15px;
text-decoration: none;
cursor: pointer; /*since the links are dummy without href values*/
/*prevent text selection*/
user-select: none;
/*static positioned elements appear behind absolutely positioned siblings(.ink in this case) hence we will make the links relatively positioned to bring them above .ink*/
position: relative;
}

/*.ink styles - the elements which will create the ripple effect. The size and position of these elements will be set by the JS code. Initially these elements will be scaled down to 0% and later animated to large fading circles on user click.*/
.hovertreenav .ink {
display: block;
position: absolute;
background: hsl(180, 40%, 80%);
border-radius: 100%;
transform: scale(0);
}
/*animation effect*/
.hovertreenav .ink.animate {
animation: ripple 0.65s linear;
}

@keyframes ripple {
/*scale the element to 250% to safely cover the entire link and fade it out*/
100% {
opacity: 0;
transform: scale(2.5);
}
}
</style>
