How can I use the same CSS for 2 divs? - html

Question

I have the 2 divs that I want styled the same. One is called #popover, the other is called #recordViewPopover. Here is my CSS for popover. How can I make #recordViewPopover use the same CSS as #popover?
#popover {

-webkit-box-shadow: 0 0 10px rgba(0, 0, 0, 0.2);
-webkit-transition: opacity 0.25s linear;

<li class='item'><a href='#' >Refresh</a></li>
<li class='item'><a href='#' >Delete</a></li>
</ul>
</div>
</div>

Answer 1

You would assign them both the same class. To do this you would have:
<div id='popover' class='someName'>
<div id='recordViewPopover' class='someName'>
and your CSS would be declared:
.someName {
//Add styles here
}

Answer 2

You could group multiple selectors:
#popover > .popover_triangle,
#recordViewPopover > .popover_triangle {
Or give the elements a class, and use a class selector where you have the id selector.
.popover > .popover_triangle {

Answer 3

#popover, #recordViewPopover {
...
}
Oh, and also
#popover > .popover_triangle,
#recordViewPopover > .popover_triangle {
...
}
But if you expect to have more divs like these two, it would indeed be better to define a class for them.
