Is it feasible to modify Less documents using JavaScript? I am attempting to adjust a property of a Less file with JavaScript. Here is my code:
document.getElementsByClassName('content-main--inner').style.border = '1px solid yellow!important';
I have experimented with both including and excluding !important, but the alteration does not take effect. It seems like the issue may lie here:
('content-main--inner')
Can you provide guidance on manipulating Less files through JavaScript?
getElementsByClassName does not return a single element, but rather a nodeList which requires iteration.
var elems = document.getElementsByClassName('content-main--inner');
for (var i=elems.length; i--;) {
elems[i].style.border = '1px solid yellow';
}
It is important to note that !important cannot be set using JavaScript or inline styles.
Altering your less file using JavaScript won't be effective because by the time you make changes, it will have already been converted to CSS
As mentioned by another user, getElementsByClassName returns a nodeList, so to modify the first element you should use this code:
document.getElementsByClassName('content-main--inner')[0].style.border = '1px solid yellow !important';
If you want to modify all elements with the class content-main--inner, you can do so with this code:
var elements = document.getElementsByClassName('content-main--inner')
for( var i = 0; i < elements.length; i++) {
elements[i].style.border = '1px solid yellow !important';
}
