Display captions in timeline?

Please let me know the position that you want to show the caption.

Hi Dominic
I’m sorry i didn’t see your reply before! I don’t know precisely where to display the legend but I only want my visitors can see them. Roll over would be a nice way. Or, just below in very small font. Thank you 

You can add the following code to the Dashboard > Customize > Additional CSS.

.timeline .hentry .entry-thumbnail {
position: relative;
}
.timeline .hentry .entry-thumbnail .image-caption {
position: absolute;
bottom: 2px;
margin: 0;
font-style: italic;
text-align: center;
left: 0;
font-size: 12px;
right: 0;
}

Then open the content.php file and replace the following code: 

<div class="entry-thumbnail">
      <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
</div>

With the following code:

<div class="entry-thumbnail">
      <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
      <p class="image-caption"><?php the_post_thumbnail_caption();?></p>
</div>

Thank you very much Dominic, that’s absolutely perfect!
However, it would be even better if the caption could appears only when we slide the cursor on the image… Possible ? Thanks

Great! Thank you
