How to remove image title and description from gallery images (lightbox view)?

Hi, I'm re-doing my website using the York template.

For my portfolio page, I'm using a gallery displayed as a grid where each image can be viewed in a lightbox.

In my gallery, I added a title and sometimes a description for SEO purposes but I realise that this data appears in the front end when the images are opened in a lightbox, which is really unattractive (see attachment).

Is there a code I can use to avoid the title and description to appear on my website but still be accessible by Google? And what do I need to do exactly?

Thanks!

Hey,

As long as you don't have any images where you do want this to display, this should work in Design > Custom CSS:

.sqs-lightbox-meta{
 display: none!important;
}

Hope this helps!

Thank you!
