border-radius: 50px;
position: relative;
}
#div2{
width: 96px;
height: 96px;
border-radius: 48px;
position: absolute;
background: white;
box-shadow: 0px 2px 4px rgba(0,0,0,0.4);
}
.open1{
background: rgba(0,184,0,0.8);
}
.open2{
top: 2px;
right: 1px;
}
.close1{
background: rgba(255,255,255,0.4);
border:3px solid rgba(0,0,0,0.15);
border-left: transparent;
}
.close2{
left: 0px;
top: 0px;
border:2px solid rgba(0,0,0,0.1);
}
<<<<<<js>>>>>>
window.onload=function(){
var div2=document.getElementById("div2");
var div1=document.getElementById("div1");
div2.onclick=function(){
div1.className=(div1.className=="close1")?"open1":"close1";
