Well, I think I’m about done. Here are some screenshots of what I think my final game will look like. I really wanted to add in text for time or score but I just can’t get fonts to work. Now I just have to figure out how to export a .jar properly. Everything I’ve tried hasn’t worked yet, but I’ll keep at it.
#gallery-1 {
margin: auto;
}
#gallery-1 .gallery-item {
float: left;
margin-top: 10px;
text-align: center;
width: 33%;
}
#gallery-1 img {
border: 2px solid #cfcfcf;
}
#gallery-1 .gallery-caption {
margin-left: 0;
}
/* see gallery_shortcode() in wp-includes/media.php */
