Custom page loader
mAuthor offers the possibility of adding a custom page loader to its presentations/lessons. A page loader can be any kind of animation that visually communicates to a user that the page is loading and to just wait for a few seconds. You may include an animated GIF of your choice together with a relevant page load progress indicator.
A page loader can be customized using an applicable CSS class in your presentation, e.g:
.ic_waitImage {
background-image: url(http://www.learnetic.com/wp-content/uploads/2016/07/LERNETIC_EN_LOGO_small.png) !important;
width: 271px !important;
height: 118px !important;
margin-left: -120px;
margin-top: -43px;
}
