Looking to add a hover border around only the edges of a div? Check out this grid layout I created using bootstrap. You can view the code on my CodePen.
<div class="product-grid col-md-4">
<a class="preview" href="#">PREVIEW</a>
</div>
.product-grid{
margin:30px 0 0 30px;
border:1px solid #ccc;
height:300px;
display:block;
}
.product-grid:hover{
border:1px solid #000;
}
/* Preview */
.preview {
opacity: 0;
position: absolute;
left: 40px;
right: 40px;
top: 0;
height: 30px;
line-height: 32px;
background-color: #fe3;
text-align: center;
text-decoration: none;
color: #000;
transition: .2s;
}
.product-grid:hover .preview {
opacity: 1;
top: 80px;
}
To help clarify, I've included a sample image below:
