Title: [Plugin: Lightbox Plus] rel="lightbox" not valid in HTML5 Last modified: August 20, 2016 --- # [Plugin: Lightbox Plus] rel="lightbox" not valid in HTML5 * Resolved [constantine.johny](https://wordpress.org/support/users/constantinejohny-1/) * (@constantinejohny-1) * [14 years ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/) * Hi, when I use rel=”lightbox”, my page doesn’t validate, saying that it is not allowed to use this value for rel attribute. Is there a way to make it valid in HTML5? For example something like data-lightbox=”” ? * [http://wordpress.org/extend/plugins/lightbox-plus/](http://wordpress.org/extend/plugins/lightbox-plus/) Viewing 9 replies - 1 through 9 (of 9 total) * [lady_r0gue](https://wordpress.org/support/users/lady_r0gue/) * (@lady_r0gue) * [13 years, 9 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740072) * I have the same problem… saw some documentation elsewhere that suggested changing all the rel= entries to class= which would seem like a neat solution – tried editing various files but no joy 🙁 * [Shigerua](https://wordpress.org/support/users/shigerua/) * (@shigerua) * [13 years, 6 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740103) * Got the same Problem. * Please fix this one, so that we can validate our pages again. * Thanks * Plugin Author [Dan Zappone](https://wordpress.org/support/users/dzappone/) * (@dzappone) * [13 years, 3 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740126) * Will be in the next update. Probably a check box named _Generate Valid HTML5 Code_. I myself have a need for this too but buggier problems got the bulk of the time. Should have another update in a day or so. * [hexagongirl](https://wordpress.org/support/users/hexagongirl/) * (@hexagongirl) * [13 years, 3 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740127) * Hi Dan, * Do you know yet when this ‘Valid HTML5 Code’ option might be available? * I’m hitting the same problem. I also get the following – is anyone aware whether this a Lightbox Plus thing, or the WP Gallery? * Element dl is missing a required instance of child element dd. * Thanks, Sarah * [Roger Sievers](https://wordpress.org/support/users/mindblossomcreations/) * (@mindblossomcreations) * [13 years, 3 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740128) * On this note, when adding a gallery into a page/post the images “a href” dont have the class or rel= attached to them? I tried the beta 2.5.6 but that didnt help either? * Is this related to the new media manager? * [http://www.larsenindustries.com/newsite/gazebos-pergolas/](http://www.larsenindustries.com/newsite/gazebos-pergolas/) * wp 3.5.1 lbs 2.5.5 * Plugin Author [Dan Zappone](https://wordpress.org/support/users/dzappone/) * (@dzappone) * [13 years, 3 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740129) * Should be updated in latest release (2.6). Also gallery issues should also be resolved for various version of WordPress. * [hexagongirl](https://wordpress.org/support/users/hexagongirl/) * (@hexagongirl) * [13 years, 3 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740131) * Great, thank you! Just updated a client site, checked the ‘Valid HTML5’ option and the validation errors have now disappeared. * Now off to find out how to get rid of my ‘Element dl is missing a required instance of child element dd.’ errors… I think the default WP gallery is the culprit this time… * Plugin Author [Dan Zappone](https://wordpress.org/support/users/dzappone/) * (@dzappone) * [13 years, 3 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740132) * No problem sorry it took me so long. Let me know because my gallery code is uses their gallery code and probably passes the same problem through. * [hexagongirl](https://wordpress.org/support/users/hexagongirl/) * (@hexagongirl) * [13 years, 3 months ago](https://wordpress.org/support/topic/plugin-lightbox-plus-rellightbox-not-valid-in-html5/#post-2740133) * I got as far as working out that the ‘missing dd’ error is due to not having captions set for my gallery images. * It’s a WP gallery thing, not specific to LBP. * It seems a bit of a flaw to me, as there are often ocassions when clients want to add a gallery with no caption. You can change the containing elements that the gallery uses on the fly via the gallery shortcode (e.g. changing dl to div etc) – but this is not ideal for clients. * The only other way I’ve found thus far invovles re-writing the gallery completely. * There is an old related trac ticket here: [http://core.trac.wordpress.org/ticket/14819](http://core.trac.wordpress.org/ticket/14819), although not sure what the solution is given [Nacin’s comment](http://core.trac.wordpress.org/ticket/14819#comment:7).
