On my Drupal 9 website, I activated the Olivero default theme. Here is a demonstration :
https://tugboat-aqrmztryfqsezpvnghut1cszck2wwasr.tugboatqa.com/
I added to my subtheme, the following code :
script.js :
(function ($, Drupal, window, document) {
$(document).ready(function () {
window.addEventListener("scroll", function() {
if (document.body.scrollTop > 1 || document.documentElement.scrollTop > 1) {
document.getElementById("site-header__inner").style.boxShadow = "-36px 1px 36px rgb(0 0 0 / 8%)";
} else {
document.getElementById("site-header__inner").style.boxShadow = "none";
}
});
});
})(jQuery, Drupal, this, this.document);
The problem is that the style is applied to the mobile menu and the desktop menu. How does this code only apply to the mobile menu ?
When I inspect the page, I find this in css, but I don't know how to use it for the solution of my question :
@media (min-width: 75rem)
body:not(.is-always-mobile-nav).toolbar-horizontal.toolbar-fixed.toolbar-tray-open .site-header__fixable.is-fixed {
top: 0.4375rem;
}
CodePudding user response:
Adding a class can be done via classList.add()
, removing a class is done via classList.remove()
In your case this would be:
document.getElementById("site-header__inner").classList.add('shadow-active')
and classList.remove('shadow-active')
in the place where you currently have the boxShadow = none
function
If you want to apply styles only to a certain viewport, use mediaqueries for that:
@media (min-width: 75rem) {
.shadow-active {
box-whadow: -36px 1px 36px rgb(0 0 0 / 8%);
}
}
