css - How can I add a box-shadow on one side of an element?

Question

I need to create a box-shadow on some block element, but only (for example) on its right side. The way I do it is to wrap the inner element with box-shadow into an outer one with padding-right and overflow:hidden; so the three other sides of the shadow are not visible.

Is there some better way to achieve this? Like box-shadow-right?

EDIT: My intentions are to create only the vertical part of the shadow. Exactly the same as what repeat-y of the rule background:url(shadow.png) 100% 0% repeat-y would do.

Answer 1

Yes, you can use the shadow spread property of the box-shadow rule:

.myDiv
{
  border: 1px solid #333;
  width: 100px;
  height: 100px;
  box-shadow: 10px 0 5px -2px #888;
}

<div class="myDiv"></div>
