If you don’t want to have white borders around the thumbnails of your subfolders, follow the instructions below to hide it:

1) Log into your App Manager and select your app.

2) Click Colors from the left-hand-side of the screen (or the middle of the screen).

3) Scroll down to the Advanced SCSS box. If there is already code in the advanced SCSS box, do not remove it. Start a new line “after” the last character in the box, then paste the above code.

/**Begin remove white border from subfolders thumbnails*/

.folder-layout.folder-l4 .folder-l4-row div.folder-l4-col {

background-size: cover;

border-style: none !important;

}

/**End remove white border from subfolders thumbnails*/

4) Click Save.
