Currently incorporating Featherlight for a lightbox feature. Encountering an issue where the background remains scrollable when the lightbox is open. Typically, lightboxes require adding a class to the body with overflow:hidden; to resolve this problem.
Seeking guidance on applying this class when the lightbox opens and removing it when closed. How can this be achieved?
To utilize the settings in your plugin call, you can make use of the beforeOpen and afterClose options in the following manner:
$.featherlight({
beforeOpen: function() {
document.body.style.overflow = 'hidden';
},
afterEnd: function() {
document.body.style.overflow = '';
}
});
To implement the solution, follow these steps:
1) Create a new CSS class named:
.preventBodyOverflow{
overflow:hidden;
}
2) Update the configuration for the Featherlight widget and adjust the beforeOpen and beforeClose callback functions as shown below:
beforeOpen: function(event){
$("body").addClass("preventBodyOverflow");
//any existing code
},
beforeClose: function(event){
$("body").removeClass("preventBodyOverflow");
//any existing code
},
