Target CSS transition at pseudo-element "Arrow"? - css

Question

I have a DIV with an "arrow" at the bottom, not unlike a speech bubble from a comic book, which appears on the hover state:
The arrow is created with the :after and :before pseudo elements.
I have a transition for the hover for the border color and the box shadow.
My problem is that the "arrow" just "appears". No fade like the other items, but I can't figure out how to target the "arrow". "All" does not look right either.
Ideally, I'd love to have a delay on the arrow and a simple fade or wipe.
Here's the CSS:
.item-selector-button {
position: relative;
text-align: center;
cursor: pointer;
border: 1px solid #cecece;
padding: 15px;
border-radius: 0;
color: #000;
width: 160px;
height: 120px;
transition: all ease-in-out 0.1s, box-shadow ease-in-out 0.1s;
}
.item-selector-button .title {
color: #3e53a4;
font-size: 12px;
margin: 0;
padding-top: -3px;
font-family: "PrecisionSans_W_Md", "Helvetica Neue", Arial, sans-serif;
}
.item-selector-button .divider {
height: 1px;
width: 20px;
background-color: #cecece;
margin: 4px auto 10px;
}
.item-selector-button .image {
background: #fff url("../images/box.png") center center no-repeat;
width: 64px;
height: 57px;
margin: 4px auto;
}
.item-selector-button:hover, .item-selector-button.hover {
padding: 14px;

.item-selector-button:hover:after, .item-selector-button.hover:after {

border-width: 12px 12px 0;
border-style: solid;
border-color: #fff transparent;
transition-delay: 0.3s;
}
.item-selector-button:hover:before, .item-selector-button.hover:before {

border-width: 12px 12px 0;
border-style: solid;
border-color: #3e53a4 transparent;
transition-delay: 0.3s;
}
.item-selector-button.disabled {
pointer-events: none;
cursor: not-allowed;
}
.item-selector-button.disabled .title {
color: #c3c3c3;
}
.item-selector-button.disabled .image {
background-image: url("../images/box-disabled.png");
}
.item-selector-button.disabled:hover {
padding: 15px;
border: 1px solid #cecece;
box-shadow: none;
}

You only have pseudoelements on the hovered element, so there is nothing to transition from/to. You need to add the pseudo elements on the non-hover state element.
Example transitioning visibility:
.item-selector-button:before {
.arrow-inside(...);
transition:all 5s ease;
transition-delay: 0.3s;
visibility:hidden;
}
.item-selector-button:after {
.arrow-outside(...);
transition:all 5s ease;
transition-delay: 0.3s;
visibility:hidden;
}
.item-selector-button:hover:before {
visibility:visible;
}
.item-selector-button:hover:after {
visibility:visible;
}
