In CSS, to exclude a particular class, we can use the pseudo-class :not selector also known as negation pseudo-class or not selector. This selector is used to set the style to every element that is not the specified by given selector. Since it is used to prevent a specific items from list of selected items.
The querySelectorAll() method in HTML is used to return a collection of an element's child elements that match a specified CSS selector(s), as a static NodeList object. The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers.
Differences: As seen above, querySelector() methodcan only be used to access a single element while querySelectorAll() method can be used to access all elements which match with a specified CSS selector. To return all matches, querySelectorAll has to be used, while to return a single match, querySelector is used.
Use :not CSS pseudo-class:
document.querySelectorAll('span.test:not(.asd)'); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
