We can use commas to separate different kinds of elements we want to select.
For instance, if we have the following HTML:
<form> </form> <p> </p> <legend> </legend>
Then we can select all the elements by writing:
const list = document.querySelectorAll("form, p, legend"); console.log(list)
list would have all the elements in the HTML in the list.
Each item separated by a comma is its own CSS selector.
