Below is the CSS code for creating a shutdown button:
.shutdown {
border: 8px solid #0cf;
border-radius: 100px;
box-shadow: 0 0 10px #0cf, inset 0 0 10px #0cf;
height: 100px;
width: 100px;
}
.shutdown .inner {
border: 5px solid #0cf;
border-radius: 100px;
box-shadow: 0 0 10px #0cf, inset 0 0 10px #0cf;
height: 30px;
left: 30px;
position: relative;
top: 30px;
width: 30px;
}
.shutdown .bar {
border-left: 5px solid #0cf;
box-shadow: 0 0 10px #0cf;
height: 20px;
left: 47px;
position: relative;
top: -15px;
width: 0;
}
.shutdown .sub-bar {
border-left: 11px solid black;
height: 30px;
margin-left: 44px;
margin-top: -20px;
position: absolute;
width: 0;
}
Here is the corresponding HTML structure:
<div class="shutdown">
<div class="inner"></div>
<div class="sub-bar"></div>
<div class="bar"></div>
</div>
