Hi Stefan,
In JA Brisk, we don’t set height for JA Slideshow lite, only min-height.
In order to edit style for this module through less, please go to:
templatesja_brisklessmod_jaslideshowlite.less
Find these line:
.ja-ss-item {
background: @BodyBackground;
display: block;
float: left;
margin: 0;
overflow: hidden;
position: absolute;
right: 0;
left: 0;
width: 100%;
min-height: 260px; <<<change to your desired value
z-index: 10;
backface-visibility: hidden;
-moz-backface-visibility: hidden;
-webkit-backface-visibility: hidden;
}
Once done, go back to template back-end, press Compile LESS to CSS.
