Lightbox title caption not working - html

Question

I'm a real novice and trying to use a web template to design my own website.
I have a basic lightbox gallery and it all works ok, but whatever I have tried, I cannot get a caption to show on the gallery image (not the thumbnail image).
This is a snippet of the html code with a single gallery item:
<div class="gallery-item">
<div class="image">
<div class="overlay">
</div>
<img src="img/gallery/gallery-item1.jpg" alt="image 4">
</div>
I've tried using title="caption" instead of data-title ="caption", but no joy. Here is the css for the lightbox:
#lightbox {
cursor: pointer;
position: fixed;
width: 100%;
height: 100%;
top: 0;
left: 0;
background: black;
/* IE Fallback (Solid Colour) */
background: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAIElEQVQ4T2NkYGDYDMRkA8ZRAxhGw4BhNAyA+WAYpAMAIFgLQfO9BoEAAAAASUVORK5CYII=);
background: rgba(0, 0, 0, 0.7);
-webkit-filter: none !important;
}
#lightbox img {
display: block;
position: absolute;
border: 5px solid #fff;
box-shadow: 0 0 20px #000;
border-radius: 1px;
}
body.blurred > * {
-webkit-filter: blur(2px);
-webkit-transform: translate3d(0, 0, 0);
}
.lightbox-loading {
background: url(../img/loading.gif) center center no-repeat;
width: 31px;
height: 31px;
margin: -16px 0 0 -16px;
position: absolute;
top: 48%;
left: 50%;
}
.lightbox-caption {
display: none;
position: absolute;
left: 0;
bottom: 0;
width: 100%;
text-align: center;
z-index: 1000;
background: #000;
background: rgba(0, 0, 0, 0.7);
}
.lightbox-caption p {
margin: 0 auto;
max-width: 70%;
display: inline-block;
*display: inline;
*zoom: 1;
padding: 10px;
color: #fff;
font-size: 12px;
line-height: 18px;
}
.lightbox-button {
position: absolute;
z-index: 9999;
background: no-repeat center center;
width: 32px;
height: 32px;
opacity: 0.4;
-webkit-transition: all 0.3s;
-moz-transition: all 0.3s;
-ms-transition: all 0.3s;
transition: all 0.3s;
}
.lightbox-button:hover,
.lightbox-button:focus {
opacity: 1;
-webkit-transform: scale(1.4);
-moz-transform: scale(1.4);
-ms-transform: scale(1.4);
transform: scale(1.4);
}
.lightbox-close {
right: 30px;
top: 30px;
background-image: url("../img/close.png");
}
.lightbox-next {
right: 30px;
top: 48%;
background-image: url("../img/next.png");
}
.lightbox-previous {
left: 30px;
top: 48%;
background-image: url("../img/previous.png");
}
any tips / help is welcomed. thanks

Answer 1

The caption is being loaded by the 'data-caption' attribute in your anchor tag.
Your anchor tags currently look like this:
You need to insert the caption like this:
For your own interest, if you look at the javascript in the source files you'll see these lines:
setCaption: function () {
var caption = $(plugin.current).data('caption');
if(!!caption && caption.length > 0) {
plugin.caption.fadeIn();
$('p', plugin.caption).text(caption);
}else{
plugin.caption.hide();
}
},
The second line says:
var caption = $(plugin.current).data('caption');
This is setting the caption to whatever text you have in the data-caption field. If it said .data('title'), then you would use data-title = "my caption"
Hope that helps.

Need more code to check I would say but you do have
.lightbox-caption {
display: none;
}
This would usually hide this class. Maybe try and remove display:none or change to block or inline etc?
