I'm having an issue with the bootstrap based Standard Theme where my gallery lightbox fails to load properly.
The lightbox loads but doesn't have the CSS necessary to float it above my page content. Adding the following CSS to the standard theme global CSS solved the issue for me.
/* JQUERY LIGHTBOX */ #jquery-overlay { position: absolute; top: 0; left: 0; z-index: 90; width: 100%; height: 500px; } #jquery-lightbox { position: absolute; top: 0; left: 0; width: 100%; z-index: 100; text-align: center; line-height: 0; } #jquery-lightbox a img { border: none; } #lightbox-container-image-box { position: relative; background-color: #fff; width: 250px; height: 250px; margin: 0 auto; } #lightbox-container-image { padding: 10px; } #lightbox-loading { position: absolute; top: 40%; left: 0%; height: 25%; width: 100%; text-align: center; line-height: 0; } #lightbox-nav { position: absolute; top: 0; left: 0; height: 100%; width: 100%; z-index: 10; } #lightbox-container-image-box > #lightbox-nav { left: 0; } #lightbox-nav a { outline: none;} #lightbox-nav-btnPrev, #lightbox-nav-btnNext { width: 49%; height: 100%; zoom: 1; display: block; } #lightbox-nav-btnPrev { left: 0; float: left; } #lightbox-nav-btnNext { right: 0; float: right; } #lightbox-container-image-data-box { font: 10px Verdana, Helvetica, sans-serif; background-color: #fff; margin: 0 auto; line-height: 1.4em; overflow: auto; width: 100%; padding: 0 10px 0; } #lightbox-container-image-data { padding: 0 10px; color: #666; } #lightbox-container-image-data #lightbox-image-details { width: 70%; float: left; text-align: left; } #lightbox-image-details-caption { font-weight: bold; } #lightbox-image-details-currentNumber { display: block; clear: left; padding-bottom: 1.0em; } #lightbox-secNav-btnClose { width: 66px; float: right; padding-bottom: 0.7em; }
