Html three divs side by side with same height - html

Question

I am trying to set three divs side by side with each equal width and height.
I am unable to remove that extra space at right at right most div. If I set its margin-right to 0 the rightmost div becomes bigger than other two.
Here is the fiddle.
Css:
.recordpopup {
position: fixed;
z-index: 10000;
top: 0;
left: 0;
height: 100%;
width: 100%;
background-color: rgba( 0, 0, 0, .8);
background-position: 50% 50%;
background-repeat: no-repeat;
display: block;
}
.recordpopup .retry {
background-color: black;
border: 1px solid white;
xborder-radius: 8px;
box-sizing: border-box;
color: white;
font-family: ProximaNova-Regular;
font-size: 16px;
font-weight: bold;
xheight: 50px;
margin-left: auto;
margin-right: auto;
padding-top: 0px;
position: relative;
text-align: center;
top: 30%;
width: 40%;
z-index: 15000;
border-radius: 8px;
padding: 20px 10px;
background-image: url('images/gray_bar.png');
background-repeat: repeat-x;
background-color: white;
}
#product-wrapper {
overflow: hidden;
margin-top: 25px;
}
.product {
float: left;
width: 33%;
display: table-cell;
width: 33.33333333%;
}
.product .container {
margin-right: 10px;
padding: 10px;
background-color: #000;
}
.product .container img {
display: block;
margin: 0 auto;
width: 100%;
}
#closeRecord {
background: black none repeat scroll 0 0;
border: 2px solid white;
border-radius: 50%;
color: white;
cursor: pointer;
height: 25px;
right: -15px;
left: right;
position: absolute;
top: -10px;
width: 25px;
}
Html:
<div class="recordpopup">
<div class="retry">
<div id="closeRecord">x</div>
<div style="width: 100%;text-align: left;margin: 5px 0;font-size: 12px;color:#333;"><span class="TitleText">Lorem Ipsum Lorem Ipsum</span> </div>
<div id="product-wrapper">
<div class="product">
<div class="container">
<img src="images/circle.png">
<p>Dummy</p>
</div>
</div>
<div class="product">
<div class="container">
<img src="images/circle.png">
<p>Dummy</p>
</div>
</div>
<div class="product">
<div class="container">
<img src="images/circle.png">
<p>Dummy</p>
</div>
</div>
</div>
</div>
</div>

Answer 1

Here is my solution.
The key is removing the margin-right: 10px and adding
.product:nth-child(1) .container{
margin-right:5px;
}
.product:nth-child(2) .container{
margin: 0 5px 0 5px;
}
.product:nth-child(3) .container{
margin-left: 5px;
}

Answer 2

The margin-right: 10px was pushing out your divs, replace it with margin: 0 5px to give a uniform look
.product .container {
margin: 0px 5px;
padding: 10px;
background-color: #000;
}
