Feature request: Need box-shadow (Items Style)

Hi!

Need add box-shadow.

I added using css. But for the css to work, I had to create the html block above, and insert the css there.

<style>
.vp-portfolio figure.vp-portfolio__item {  
  box-shadow: 1px 3px 3px 1px #333;  
}
.vp-portfolio__items-wrap .vp-portfolio__items  .vp-portfolio__item-wrap {
  padding: 7px !important;
}
.vp-portfolio__items-wrap {
  margin-left: -7px;
  margin-right: -7px;
}
.vp-portfolio__items-style-emerge .vp-portfolio__item a {
  transition: all 400ms;
}
</style>
