I have this jsfiddle demo.
I have an thumbnail of a vimeo movie (here it is a placeholder) in the center I would like a play btn.
The whole of the image will be clickable so the play button is just for illustration.
I would like the play button dead center.
I can do it with negative margins but I won't really know the size of the play button.
How can I dead center the play button with knowing it dimensions.
.video_thumbnail {
border: 1px solid red;
position: relative;
}
.video_thumbnail:hover {
cursor: pointer;
}
.video_thumbnail .play-btn {
background: white;
background: blue;
display: inline-block;
padding: 25px;
position: absolute;
top: 50%;
left: 50%;
/*
margin-left: -35px;
margin-top: -35px;
*/
}
.video_thumbnail .play-btn:after {
content: "";
display: block;
position: relative;
left: 2px;
width: 0;
height: 0;
border-style: solid;
border-width: 10px 0 10px 20px;
border-color: transparent transparent transparent white;
}
