Answer 1

That called attribute , to set attribute you could use the methods below.

Pure JS setAttribute() method :

element.setAttribute('name','value');

jQuery attr() method :

$(element).attr('name','value');

Example :

document.querySelector('.content').setAttribute('something',''); //Pure JS
//Or
$('.content').attr('something',''); //jQuery

Hope this helps.

Answer 2

使用jQuery：

$('.content').attr('something','');

Answer 3

If you want to add the attribute if window width is greater then 960

if ( window.innerWidth > 960 ) {

    document.querySelector('.content').setAttribute('something','')

}
