I have been trying this for the last 2 hours and nothing seems to work. I've edited both the user.css and default.css files to try and resize the black slideshow overlay and it never resizes the height of it. I can quite easily alter it in any other way, width, color etc, but the height always remains constant.

I've been using this to try alter the height, but to no avail (ignoring the values, because the height doesn't change regardless of the value I use:

.featured-entry { height: 24px; top: -24px; }
.featured-entry .entry-summary { display: none; }

Please let me know of anything else I can try to fix this, all I want to do is resize the overlay so it takes up less of the slideshow.

Thanks.

Doesn't help sorry, that just resizes the slideshow box itself, not the excerpt overlay.

same with me, can resize the overlay 84 to 50

this overlay css, but i'dont know, change this css
.featured-entry {
  height:84px;
  top:-84px;
}
