*/

.viewport {
    margin: 0 0 (@line-height-computed / 2); //inherit from p (bootstrap/style.less)

    .box-shadow(0 3px 10px rgba(0, 0, 0, 0.175));

    min-height:200px;
    min-width: 200px;
    max-width: 100%; //shrink images to 100% width of the parent element, if needed

}

//During loading, iframes are temporarily added to the body -- but not displayed
//After loading, the iframes are put into the viewport by js.
body > iframe { .hidden; }

//avoid that the default background of an iframe is transparent, and contents becomes unreadible
//(eg needed for View Page Source
