Displaying / Styling Ad Slots

A successfully rendered ad will append additional DOM elements to the passed ad container. These will be stretched to the exact size of the ad, so please take care that your ad container is expandable by its children (avoid overflow: hidden, height:0, display:none etc). If you need a height:0 i. e. to initialize a slideDown animation, you can start with height:auto, attach a callback to the insertAd call and listen to the insertable call. At that time you can apply any rules like height:0 without interfering with the integrated viewability check.

Please avoid any CSS rules for children of the ad container. Somtag will take care of this.

If no ad could be delivered, Somtag will collapse any content of the ad container and will apply the class class="somtag--collapsed" to the ad container.
