The Play/Pause button will be the universally recognized pause and play symbols displayed using the link color of you theme.
There is no provision for adding text labels. The Pause/Play icons are in fact icons provided by the underlying FlexSlider script.
It should be possible to modify the following CSS to provide custom Icons/labels for the defaults:
/*
Pause/Play
*/
.atwk-pauseplay span {
text-transform: capitalize;
}
.atwk-pauseplay a { /* position the pause play button */
display: block;
width: 25px;
height: 25px;
position: absolute;
bottom: 20px;
left: 20px;
opacity: 0.8;
z-index: 10;
overflow: hidden;
cursor: pointer;
color: #ccc;
text-shadow: 5px 2px 4px black;
}
.atwk-pauseplay a:before {
font-family: “flexslider-icon”;
font-size: 20px;
display: inline-block;
content: ‘f004’;
}
.atwk-pauseplay a:hover {
color:#888;
opacity: 1;
}
.atwk-pauseplay a.atwk-play:before {
content: ‘f003’;
}
