Can you explain how to modify the property of the :before element?
For instance:
Using CSS:
.myclass:before {
content: '';
position: absolute;
left: 40px;
top: -10px;
}
With jQuery:
myElement.addClass('myclass');
I need to update:
from
left: 40px
to
left: 100px
Any suggestions on how I can achieve this?
Pseudo-elements are not included in the DOM structure, making them inaccessible for manipulation using jQuery or JavaScript.
One workaround is to directly inject CSS styles using jQuery:
$('head').append('<style>.myclass:before{left:100px;}</style>');
Alternatively, you can add another class with the desired CSS properties:
CSS
.myclass.active:before {
left: 100px;
}
jQuery
$("#myElement.myclass").addClass("active");
As far as my understanding goes, there isn't a straightforward method to achieve this. If you are determined to modify CSS rules directly, then delving into the browser's CSSOM interfaces is necessary. However, in most scenarios, it would be simpler to create a distinct CSS rule that handles the required adjustments for your :before pseudo-element when applying an additional CSS class to the element itself.
