CSS: create material design shadow issue - html

Question

I need to create this button with CSS only and have an issue with box shadow. There are two different shadows on this button: one yellow, one black. The maximum what I get is this
.button {
height: 81px;
width: 250px;
text-align: center;
font-family: 'Celias_Medium', 'Open Sans:500', sans-serif;
font-size: 11px;
line-height: 3.3;
letter-spacing: 0.4px;
cursor: pointer;
outline: none;
display: block;
vertical-align: top;
padding: 23px 0 26px 0;
text-transform: uppercase;
color: #000000;
background-color: #fbfb5c;
box-shadow: 0 20px 90px -30px rgba(251, 251, 92, 0.9), 0 40px 90px -50px rgba(0, 0, 0, 0.5)
}
<div class="button">ADD 7 Activities</div>
Here is result. Is there any other solution to get this result?

Generally speaking material buttons would look something like this, but I don't really know what you're asking.
.button {
height: 81px;
width: 250px;
text-align: center;
font-family: Celias_Medium, 'Open Sans:500', sans-serif;
font-size: 11px;
line-height: 3.3;
letter-spacing: .4px;
cursor: pointer;
vertical-align: top;
padding: 23px 0 26px;
box-sizing: border-box;
text-transform: uppercase;
background-color: #fbfb5c;
border-radius: 4px;
margin: 16px 0;
box-shadow: 0 1px 3px rgba(0, 0, 0, .12), 0 1px 2px rgba(0, 0, 0, .24);
transition: all .3s cubic-bezier(.25, .8, .25, 1)
}
.button:hover {
box-shadow: 0 14px 28px rgba(0, 0, 0, .25), 0 10px 10px rgba(0, 0, 0, .22)
}
<div class="button">
Button no. 1
</div>
<div class="button">
Button no. 2
</div>
<div class="button">
Button no. 3
</div>
<div class="button">
Button no. 4
</div>
<div class="button">
Button no. 5
</div>
