If we use an attribute selector to select an element by its ID then it will have a lower level of specificity than if it was selected with an ID selector.
For e.g. We can target the same element with [id="ID_name"] and #ID_name but with lower specificity.
HTML
<div id="ID_name">...</div>
CSS
#ID_name { ... } /* High specificity */
[id="ID_name"] { ... } /* Low specificity */
attributes css selectors elements html tags pseudo-elements Specificity
